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.
