Torsional behaviour of filament wound kenaf yarn fibre reinforced unsaturated polyester composite hollow shafts

Effect of water absorption on the mechanical properties of hemp fibre reinforced unsaturated polyester composites

Hemp fibre reinforced unsaturated polyester composites (HFRUPE) were subjected to water immersion tests in order to study the effects of water absorption on the mechanical properties. HFRUPE composites specimens containing 0, 0.10, 0.15, 0.21 and 0.26 fibre volume fraction were prepared. Water absorption tests were conducted by immersing specimens in a de-ionised water bath at 25 C and 100 C fo...

Thermogravimetric analysis of aluminised E-glass fibre reinforced unsaturated polyester composites

Novel aluminised E-glass fibre reinforced unsaturated polyester composites, originally formulated for enhanced thermal and electrical shielding properties were evaluated in terms of their thermal performance. The thermal degradation of these specimens was analysed using a thermogravimetric analyser (TGA). The samples were heated from ambient temperature to 500 1C at a heating rate of 20 1C/min....

Flexural Properties of Kenaf Fibre Mat Reinforced PLA Composites

The potential use of natural biopolymer composites in a variety of applications that requires biodegradability and better mechanical properties has renewed many researchers interest on the composites. This research involves the analysis of flexural properties for natural fibers specifically kenaffiber mat in a polylactic acid (PLA) matrix (KMPLA). The polylactic acid has been chosen as a matrix...

Characterization of Laccase-Treated Kenaf Fibre Reinforced Recycled Polypropylene Composites

Raw and laccase-treated kenaf fibre (KF) were used individually to reinforce recycled polypropylene (RPP) using extrusion and injection moulding. Laccase was used to modify the surface of the fibre to improve the compatibility between fibre and matrix. Enzyme concentration and soaking time were considered as the treatment parameters. Maleic anhydride grafted polypropylene (MAPP) was used with a...
