ABSTRACT
Modern society is experiencing increasing numbers plastic waste materials because of the lack of ability and management efficiency. The waste of plastics is increasing rapidly every day. In order to produce high loading biocomposites, two types of recycled plastic high density polyethylene (rHDPE) and poly (ethylene terephthalate) (rPET) were mixed with various amount of rice husk content. The ratio of plastics used in the study is 75:25 (rHDPE/rPET). Percentages of rice RH in this study are 40, 50, 60, 70 and 80 wt%. Maleic anhydride-modified polyethylene (MAPE) was added as a coupling agent. Tensile and flexural tests demonstrated that rHDPE/rPET/RH biocomposites present improved mechanical performances comparatively to the unfilled polymer blend. Highest tensile strength was recorded by composite filled with 60 wt% of RH. Whilst, composite filled 70 wt% of RH gives the optimum Young's modulus value. Flexural testing results show the biocomposite with 80 wt% of RH give the maximum values on modulus of elasticity (MOE) and modulus of rupture (MOR), which are 46 MPa and 5195 MPa, respectively. The addition of RH in the polymer blend drastically reduced the impact strength. Microstructure analysis of the composite fracture surface using a scanning electron microscope (SEM) to investigate interfacial bonding between the polymer blends and rice husk.
