Fiber processing is an important factor that affects the physical and mechanical properties of long kenaf fiber. Three natural fibers: kenaf, jute, and sunn hemp as potential candidates were compared in terms of physical, thermal and mechanical properties. ; [email protected] 2 Faculty of Engineering, Universiti Pertahanan Nasional Malaysia (UPNM), Kem Sg Besi ⦠Anyanwu et al-This content was downloaded from IP address 40.77.167.75 on 24/04/2020 at 01:47. properties. Polym. The plain woven kenaf fibre was prepared and cut to fabricate composite samples according to the ASTM standards. As usual, natural fibres have some issues and disadvantages when used as reinforcements for polymeric composites. Here, we reported a chemical modification of kenaf fiber using propionic anhydride to enhance the compatibility with the epoxy matrix. Therefore, some modification performed on fibers such as chemical treatment was carried out. Three types of thermoset resins were used to fabricate the composite samples, namely, epoxy, unsaturated polyester, and vinyl ester resin. These show that there is a possibility to use kenaf as an alternative raw material for MDF industries. It can be concluded that Kenaf powder composite has more opportunity for further growth with new methods and technologies which keeps on evolving. A3 Preparation and Properties of Kenaf Bast Fiber Filled Plasticized Poly(lactic acid) Composites It is also noticed that increasing volume fraction of kenaf fiber in hybrid composites reduces tensile and flexural properties. The fiberboards achieved sound mechanical and physical properties with fibers 0.81 mm long and with an aspect ratio of 23.4. The kenaf fibres were processed through water retting, chemical retting and mechanical extractions. The surface morphology of the fractured specimens such as fiber pullout and matrix crack was examined using scanning electron microscopy.

Introduction Since ancient civilisation, natural composites had been used to build up structures or products. The physical-mechanical properties, such as color, tensile strength, and moisture regain (MR), are the main characteristics that influence the processing and performance on the final products from kenaf fiber. The incorporation of the modified woven and nonwoven kenaf fibers into the epoxy matrix resulted in the improvement of the thermal and mechanical properties of the composite. Sci.

The investigation was carried out to study the effect of chemical treatment on chemical and thermal properties of kenaf fiber and its composites. The aims of the study are to characterize and evaluate the physical and mechanical properties of continuous unidirectional kenaf fiber epoxy composites with various fiber volume fractions. Kenaf (Hibiscus Cannabinus L.) fibres are thermally and alkali treated to enhance the interfacial bond between the fibre-matrix, the mechanical properties of the fibre itself, the fibre-reinforced thermally activated alum sludge ash (AASA) and the nanosilica (NS) blended cementitious composites.

It is also noticed that increasing volume fraction of kenaf fiber in hybrid composites reduces tensile and flexural properties. Combining kenaf fiber with other resources provides a strategy for producing advanced composite materials that take advantage of the properties of both types of resources. Gum, as the important noncellulosic tissue present in kenaf fiber, has a close relation with downstream processing and product properties, so the predominant task in pretreatment of kenaf fiber for textile application, retting, is to remove gum including pectin, hemicellulose, lignin, and other impurities without damage to cellulose fiber. Kenaf chips were defiberated under 3 to 7 bar for 3 and 5 min. Crossref .
