In this study the effects of fibre loading and coupling agent on
the performance of Empty Fruit Bunch (EFB) fibre composites of oil
palm biomass were investigated. The dried EFB were ground in random
sizes for composite production. Ground fibre was compounded with
polypropylene (PP) by means of a twin-screw compounder for
preparing of EFB/PP composites. Maleic anhydride grafted
polypropylene (MAPP) was used as a coupling agent. The incorporated
fibre contents for EFB composites were 10 to 40% (by weight). The
test specimens were prepared by injection moulding. The composites
were characterized by melt flow index, mechanical tests such as
tensile strength (TS), tensile modulus (TM), flexural strength
(FS), flexural modulus (FM) and impact strength (IS). Surface
morphology was also studied by SEM. Bonding/interaction mechanism
was studied by FTIR and thermal stability was studied by TGA
analysis form where the activation energy was calculated for
different composites. It was found that both coupling agent and
fibre content play in important role on composites properties.
