However, the durability of the conductive fiber after the wash process is an important issue for conductive fiber applications in e-textiles. Therefore, it is necessary for conductive fiber with good performance on electrically conductive behavior during the product life cycle. In this research, the PET-based conductive fiber was prepared by silver conductive ink continuous coating. The conductive fiber showed low fiber resistance (10-¹~10Ω/cm), and the conductive behavior still had good performance (fiber resistance:10-¹~10Ω/cm， percentage of fiber resistance change:<60%) after the water wash durability test (AATCC-135， 30 times). This research provides a better solution to resolve the issues of resistance increase after the water wash process due to the damage to the conductive fiber structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PET" title="PET">PET</a>, <a href="https://publications.waset.org/abstracts/search?q=conductive%20fiber" title=" conductive fiber"> conductive fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=e-textiles" title=" e-textiles"> e-textiles</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20devices" title=" wearable devices"> wearable devices</a> </p> <a href="https://publications.waset.org/abstracts/166142/characteristics-of-pet-based-conductive-fiber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166142.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1270</span> A Study on the Improvement of the Bond Performance of Polypropylene Macro Fiber according to Longitudinal Shape Change</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sung-yong%20Choi">Sung-yong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Woo-tai%20Jung"> Woo-tai Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-hwan%20Park"> Young-hwan Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study intends to improve the bond performance of the polypropylene fiber used as reinforcing fiber for concrete by changing its shape into double crimped type through the enhancement its fabrication process.

To fabricate molded fiber products, besides using conventional meshing tools, 3D printing is employed to manufacture the molded fiber screen. 3D printing technique allows printing molded fiber screens with complex geometry, flexible in pore size and shape. The 3D printed molded fiber screens are in the progress of investigation to improve the de-watering efficiency, fiber collection, mechanical strength, etc. In addition, the fiber distribution on the screen is also necessary to access the quality of the screen. Besides using experimental methods to capture the fiber distribution on screen, simulation also offers using tools to access the uniformity of fiber. In this study, the fiber was simulated using the multi-sphere model to simulate the fibers. The interaction of the fibers was able to mimic by employing the discrete element method. The fiber distribution was captured and compared to the experiment. The simulation results were able to reveal the fiber deposition layer upon layer and explain the formation of uneven thickness on the tilted area of molded fiber screen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20printing" title="3D printing">3D printing</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-jet%20fusion" title=" multi-jet fusion"> multi-jet fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=molded%20fiber%20screen" title=" molded fiber screen"> molded fiber screen</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20element%20method" title=" discrete element method"> discrete element method</a> </p> <a href="https://publications.waset.org/abstracts/157099/simulation-of-fiber-deposition-on-molded-fiber-screen-using-multi-sphere-discrete-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157099.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1268</span> Effect of Fiber Content and Chemical Treatment on Hardness of Bagasse Fiber Reinforced Epoxy Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Varun%20Mittal">Varun Mittal</a>, <a href="https://publications.waset.org/abstracts/search?q=Shishir%20Sinha"> Shishir Sinha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present experimental study focused on the hardness behavior of bagasse fiber-epoxy composites.

Samples of fiber were analyzed using standard measurements for wool fiber length (WFL), mean fiber diameter (MFD), coefficient of variation of wool fiber diameter (FDCV), breaking strength, elongation, crimp, cleanness and moisture content. Based on the result all parameters shows that there is a great potential of getting of wool fiber from the skin of sheep and according to the standards of its property and grading system based on wool fiber fineness is medium to course. These types of fibers can be making carpets, blankets, rugs, coverings and other products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fiber" title="Fiber">Fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=Fineness" title=" Fineness"> Fineness</a>, <a href="https://publications.waset.org/abstracts/search?q=Carpet" title=" Carpet"> Carpet</a>, <a href="https://publications.waset.org/abstracts/search?q=Fleece" title=" Fleece"> Fleece</a>, <a href="https://publications.waset.org/abstracts/search?q=Raw%20Wool" title=" Raw Wool"> Raw Wool</a> </p> <a href="https://publications.waset.org/abstracts/119161/characterization-of-the-physical-properties-of-sheep-wool-fiber-in-amhara-national-regional-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119161.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1263</span> Impact Modified Oil Palm Empty Fruit Bunch Fiber/Poly(Lactic) Acid Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20D.%20H.%20Beg">Mohammad D.

Effect of fiber treatment on composite was characterized by tensile strength (TS), tensile modulus (TM) and impact strength (IS).

The thermo-mechanical properties of PBI fiber reinforced HDPE composite samples (1%, 4% and 8% fiber content) of fiber lengths 3 mm and 6 mm were investigated using differential scanning calorimeter (DSC), universal testing machine (UTM), rheometer and scanning electron microscopy (SEM). The effect of fiber content and fiber lengths on the thermo-mechanical properties of the HDPE-PBI composites was studied. The DSC analysis showed decrease in crystallinity of HDPE-PBI composites with the increase of fiber loading. Maximum decrease observed was 12% at 8% fiber length. The thermal stability was found to increase with the addition of fiber. T50% was notably increased to 40oC for both grades of HDPE using 8% of fiber content. The mechanical properties were not much affected by the increase in fiber content. The optimum value of tensile strength was achieved using 4% fiber content and slight increase of 9% in tensile strength was observed. No noticeable change was observed in flexural strength. In rheology study, the complex viscosities of HDPE-PBI composites were higher than the HDPE matrix and substantially increased with even minimum increase of PBI fiber loading i.e. 1%. We found that the addition of the PBI fiber resulted in a modest improvement in the thermal stability and mechanical properties of the prepared composites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PBI%20fiber" title="PBI fiber">PBI fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20density%20polyethylene" title=" high density polyethylene"> high density polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a>, <a href="https://publications.waset.org/abstracts/search?q=melt%20blending" title=" melt blending"> melt blending</a> </p> <a href="https://publications.waset.org/abstracts/26194/thermo-mechanical-properties-of-pbi-fiber-reinforced-hdpe-composites-effect-of-fiber-length-and-composition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26194.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">365</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1260</span> A Comparative Study on Indian and Greek Cotton Fiber Properties Correlations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Nakib%20Ul%20Hasan">Md.

Spinners work tirelessly to ensure consistent yarn quality by using the different origins of fibers to maximizes the profit margin. Spinners often fail to select desired raw materials of various origins to achieve an appropriate mixing plan due to the lack of knowledge on the interrelationship among fiber properties. The purpose of this research is to investigate the correlations among dominating fiber properties such as micronaire, strength, breaking elongation, upper half mean length, length uniformity index, short fiber index, maturity, reflectance, and yellowness. For this purpose, fiber samples from 500 Indian cotton bales and 350 Greek cotton bales were collected and tested using the high volume instrument (HVI). The fiber properties dataset was then compiled and analyzed using python 3.7 to determine the correlations matrix. Results show that Indian cotton fiber have highest correlation between strength-mat = 0.84, followed by SFI-Unf =-0.83, and Neps-Unf = -0.72. Greek cotton fiber, in contrast, have highest correlation between SFI-Unf =-0.98, followed by SFI-Mat = 0.89, +b-Len = 0.84, and Str-Mat = 0.74. Overall, the Greek cotton fiber showed a higher correlational matrix than compared to that of Indian cotton fiber. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cotton%20fiber" title="cotton fiber">cotton fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20properties%20correlation" title=" fiber properties correlation"> fiber properties correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=Greek%20cotton" title=" Greek cotton"> Greek cotton</a>, <a href="https://publications.waset.org/abstracts/search?q=HVI" title=" HVI"> HVI</a>, <a href="https://publications.waset.org/abstracts/search?q=Indian%20cotton" title=" Indian cotton"> Indian cotton</a>, <a href="https://publications.waset.org/abstracts/search?q=spinning" title=" spinning"> spinning</a> </p> <a href="https://publications.waset.org/abstracts/130187/a-comparative-study-on-indian-and-greek-cotton-fiber-properties-correlations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130187.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">162</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1259</span> Mechanical Properties of Kenaf Reinforced Composite with Different Fiber Orientation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20C.%20Ching">Y.

Pickering</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Composite waste from manufacturing can consist of different fiber materials, including blends of different fiber. Commercially, the recycling of composite waste is currently limited to carbon fiber waste and recycling glass fiber waste is currently not economically viable due to the low cost of virgin glass fiber and the reduced mechanical properties of the recovered fibers. For this reason, the recycling of hybrid fiber materials, where carbon fiber is combined with a proportion of glass fiber, cannot be processed economically. Therefore, a separation method is required to remove the glass fiber materials during the recycling process. An electrostatic separation method is chosen for this work because of the significant difference between carbon and glass fiber electrical properties. In this study, an experimental rig has been developed to measure the electrostatic charge achievable as the materials are passed through a tube. A range of particle lengths (80-100 µm, 6 mm and 12 mm), surface state conditions (0%SA, 2%SA and 6%SA), and several tube wall materials have been studied. A polytetrafluoroethylene (PTFE) tube and recycled without sizing agent was identified as the most suitable parameters for the electrical separation method. It was also found that shorter fiber lengths helped to encourage particle flow and attain higher charge values. These findings can be used to develop a separation process to enable the cost-effective recycling of hybrid fiber composite waste. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrostatic%20charging" title="electrostatic charging">electrostatic charging</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20fiber%20composites" title=" hybrid fiber composites"> hybrid fiber composites</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20fiber%20composites" title=" short fiber composites"> short fiber composites</a> </p> <a href="https://publications.waset.org/abstracts/138679/separation-of-composites-for-recycling-measurement-of-electrostatic-charge-of-carbon-and-glass-fiber-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138679.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1257</span> Preparation of Water Hyacinth and Oil Palm Fiber for Plastic Waste Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pattamaphorn%20Phuangngamphan">Pattamaphorn Phuangngamphan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rewadee%20Anuwattana"> Rewadee Anuwattana</a>, <a href="https://publications.waset.org/abstracts/search?q=Narumon%20Soparatana"> Narumon Soparatana</a>, <a href="https://publications.waset.org/abstracts/search?q=Nestchanok%20Yongpraderm"> Nestchanok Yongpraderm</a>, <a href="https://publications.waset.org/abstracts/search?q=Atiporn%20Jinpayoon"> Atiporn Jinpayoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Supinya%20Sutthima"> Supinya Sutthima</a>, <a href="https://publications.waset.org/abstracts/search?q=Saroj%20Klangkongsub"> Saroj Klangkongsub</a>, <a href="https://publications.waset.org/abstracts/search?q=Worapong%20Pattayawan"> Worapong Pattayawan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims to utilize the agricultural waste and plastic waste in Thailand in a study of the optimum conditions for preparing composite materials from water hyacinth and oil palm fiber and plastic waste in landfills. The water hyacinth and oil palm fiber were prepared by alkaline treatment with NaOH (5, 15 wt%) at 25-60 °C for 1 h. The treated fiber (5 and 10 phr) was applied to plastic waste composite. The composite was prepared by using a screw extrusion process from 185 °C to 200 °C with a screw speed of 60 rpm. The result confirmed that alkaline treatment can remove lignin, hemicellulose and other impurities on the fiber surface and also increase the cellulose content. The optimum condition of composite material is 10 phr of fiber coupling with 3 wt% PE-g-MA as compatibilizer. The composite of plastic waste and oil palm fiber has good adhesion between fiber and plastic matrix. The PE-g-MA has improved fiber-plastic interaction.

The whole world is concerned about conserving the environment. Henceforth, the demand for natural and decomposable materials is increasing. The application of natural fibers is widely used in aerospace for manufacturing aircraft bodies, and ship construction in navy fields. Based on the literature review, researchers and scientists are replacing synthetic fibers with natural fibers. The selection of these fibers mainly depends on lightweight, easily available, and economical and has its own physical and chemical properties and many other properties that make them a fine quality fiber. The pineapple fiber has desirable properties of good mechanical strength, high cellulose content, and fiber length. Hybrid composite was prepared using different proportions of pineapple fiber and banana fiber, and their ratios were varied in 90% polypropylene mixed with 5% banana fiber and 5% pineapple fiber, 85% polypropylene mixed with 7.5% banana fiber and 7.5% pineapple fiber and 80% polypropylene mixed with 10% banana fiber and 10% pineapple fiber. By impact experimental analysis, we concluded that the combination of 90% polypropylene and 5% banana fiber and 5% pineapple fiber exhibits a higher toughness value with mechanical strength. We also conducted scanning electron microscopy (SEM) analysis which showed better fiber orientation bonding between the banana and pineapple fibers with polypropylene composites.

However, the heavy utilization of these composite materials also increases the importance of the recycling of these composite materials. A team of Purdue University School of Aviation and Transportation Technology (SATT) faculty and students have partnered to investigate the characteristics of 3D printed recycled carbon fiber. A prototype of a 3D printed recycled carbon fiber part was provided by an industry partner and different sections of the prototype were used to create specimens. A furnace was utilized in order to remove the polymer from the specimens and the specimen’s fiber content and fiber length was calculated from the remaining fibers. A differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) test was also conducted on the 3D printed recycled carbon fiber prototype in order to determine the prototype’s degree of cure at different locations. The data collected from this study provided valuable information in the process improvement and understanding of 3D printed recycled carbon fiber. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20printed" title="3D printed">3D printed</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20fiber" title=" carbon fiber"> carbon fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20content" title=" fiber content"> fiber content</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a> </p> <a href="https://publications.waset.org/abstracts/100895/investigating-the-fiber-content-fiber-length-and-curing-characteristics-of-3d-printed-recycled-carbon-fiber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100895.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1253</span> Effect of the Ratio, Weight, Treatment of Loofah Fiber on the Mechanical Properties of the Composite: Loofah Fiber Resin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Siahmed">F.

The result of alkaline hydrolysis of PAN fiber could be formed the products with conjugated sequences of –C=N–, acrylamide, sodium acrylate, and amidine. In this study, PAN fiber was hydrolyzed in a solution of sodium hydroxide, and this hydrolyzed PAN (HPAN) fiber was used to prepare conductive composite fiber by silver particles. The electrically conductive PAN fiber has the usage potential to produce variety of materials such as antistatic materials, life jackets and static charge reducing products. We monitored the change in the weight loss values of the PAN fiber with hydrolysis time. It was observed that a 60 % of weight loss was obtained in the fiber weight after 7h hydrolysis under the investigated conditions, but the fiber lost its fibrous structure. The hydrolysis time of 5h was found to be suitable in terms of preserving its fibrous structure. The change in the conductivity values of the composite with the preparation conditions such as hydrolysis time, silver ion concentration was studied. PAN fibers with different degrees of hydrolysis were treated with aqueous solutions containing different concentrations of silver ions by continuous stirring at 20 oC for 30 min, and the composite having the maximum conductivity of 2 S/cm could be prepared. The antibacterial property of the conductive HPAN fibers participated silver was also investigated. While the hydrolysis of the PAN fiber was characterized with FTIR and SEM techniques, the silver reduction process of the HPAN fiber was investigated with SEM and TGA-DTA techniques. The SEM micrographs showed that the surface of HPAN fiber was rougher and much more corroded than that of the PAN fiber.

In this study, behaviours of activated carbon nano fiber (ACNF), carbon nano-fiber (CNF), Polyacrylonitrile/carbon nanotube (PAN/CNT), Polyvinyl alcohol/nano silver (PVA/Ag) in PEM fuel cells are investigated experimentally. This material was used as gas diffusion layer (GDL) in PEM fuel cells. When the performances of these cells are compared to each other at 5x5 cm2 cell, it is found that the PVA/Ag exhibits the best performance among all. In this work, nano fiber and nano fiber/nano particles electrical conductivities have been studied to understand their effects on PEM fuel cell performance. According to the experimental results, the maximum electrical conductivity performance of the fuel cell with nanofiber was found to be at PVA/Ag. The electrical conductivities of CNF, ACNF, PAN/CNT are lower for PEM. The resistance of cell with PVA/Ag is lower than the resistance of cell with PAN/CNT, ACNF, CNF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=proton%20exchange%20membrane%20fuel%20cells" title="proton exchange membrane fuel cells">proton exchange membrane fuel cells</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nano%20fiber" title=" carbon nano fiber"> carbon nano fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=activate%20carbon%20nano-fiber" title=" activate carbon nano-fiber"> activate carbon nano-fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=PVA%20fiber" title=" PVA fiber"> PVA fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=PAN%20fiber" title=" PAN fiber"> PAN fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotube" title=" carbon nanotube"> carbon nanotube</a>, <a href="https://publications.waset.org/abstracts/search?q=nano%20particle%20nanocomposites" title=" nano particle nanocomposites"> nano particle nanocomposites</a> </p> <a href="https://publications.waset.org/abstracts/38111/experimental-investigation-of-proton-exchange-membrane-fuel-cells-operated-with-nano-fiber-and-nano-fibernano-particle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38111.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">391</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1248</span> Localization Problem in Optical Fiber Sensors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Zyczkowski">M.

The theoretical parameters of a given reinforcement are usually known and widely used to predict the behavior of the material. In this work, we propose an image processing approach to estimate true principal directions and fiber orientation during injection molding processes of short fiber reinforced thermoplastics. Generally, a group of fibers are described in terms of probability distribution function or orientation tensor. Numerical techniques for the prediction of fiber orientation are also considered for concentrated situations. The flow was considered to be incompressible, and behave as Newtonian fluid containing suspensions of short-fibers. The governing equations, of this problem are: the continuity, the momentum and the energy. The obtained results were compared to available experimental findings.

Among all advantages there are few issues which need to be addressed, those issues are the poor adhesion and compatibility between two opposite nature materials that is fiber and matrix and their relatively high water absorption. Therefore, natural fiber modifications are necessary to improve their adhesion with different matrices. Excellent properties could be achieved with the surface treatment of these natural fibers ultimately leads to property up-gradation of their reinforced composites with different polymer matrices. Lot of work is going on to improve the adhesion between reinforced fiber phase and polymer matrix phase to improve the properties of composites. Researchers have suggested various methods for natural fiber treatment like silane treatment, treatment with alkali, acetylation, acrylation, maleate coupling, etc. In this study a review is done on the different methods used for the surface treatment of natural fibers and what are the advance treatment methodologies for natural fiber surface treatment for property improvement of natural fiber reinforced polymer composites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composites" title="composites">composites</a>, <a
