    This study compares the mechanical properties of recycled high-density polyethylene (r-HDPE)/rice husk (RH) composites from a twin-screw extruder and a heated two-roll mill, and the effect of different filler loadings using different melt blending processes on the mechanical properties of r-HDPE/RH composites. Polyethylene-graft-maleic anhydride (MAPE) acts as the coupling agent to enhance interfacial bonding between the fibre and the polymer matrix. The filler loading used was in the range of 10-40 wt. %. In this work, r-HDPE/RH blends were prepared using a twin-screw extruder and a heated two-roll mill. The ratio of 70/30 twin-screw extruder compounded composites significantly showed higher tensile based on improved to about 45.5% at 11 MPa compared to those compounded in the heated two-roll mill. The same ratio showed an increment almost up to 9% of elongation at break. It has also been verified that the higher filler loading used reduced the tensile strength and elongation at break, while the Young's modulus increased. The result was evidenced by the increase in water absorption and longer burning time as the filler loading increased.

    In this project, extruded rice husk (RH) / low density polyethylene (LDPE) with and without maleic anhydride (MAPE) were thermally treated at temperatures of 105C and 125C. The duration of annealing was carried out to one and three hours before going through to the injection moulding to get the dumbbell shape for tensile testing. From the testing, the trend of results obtained where tensile and modulus of elasticity of RH/LDPE increase with temperature of 125 C which are 5 MPa and 261 MPa respectively. However, the elongation at break shows a reduction value where 105 C temperature is 12% while 125C is 8%. Results obtained for RH/LDPE with and without MAPE show the composites with added MAPE have better tensile strength and modulus of elasticity. Meanwhile, the elongation at break of composites with MAPE is lower than composites without MAPE.

    The goal of this study was to investigate the effect of surface treatment on rice husk reinforced recycled high density polyethylene (rHDPE) composites. Three types of surface treatments on rice husk were carried out which were maleated treatment, alkali treatment and acrylic acid treatment. Water absorption test was examined in distilled water. It showed that the lower the loading of rice husk, the lower the water absorption percentage. Maleated treatment on rice husk reinforced rHDPE has the highest resistance of water absorption tendency. Scanning electron microscope analysis of the composites showed that the lower the rice husk loading, the better the interfacial bonding of the composites. Maleated treatment of rice husk also showed that there is no gaps formed in the structure.

    The aim of this work was to investigate the effect of surface treatment on rice husk reinforced recycled high density polyethylene (rHDPE) composites. Three types of surface treatment on rice husk were carried out which were maleated treatment, alkaline treatment and acrylic acid treatment. The characteristics and mechanical properties of the composites were analysed. The results for all treatments showed that tensile strength and break elongation of composites decreased significantly when the rice husk filler loading increased. Further findings showed that maleated treatment on rice husk can further enhance the mechanical properties due to the present of ester bond formed in FTIR analysis.
