In the present work, the effect of rice husk filler loading (10%, 20%, 25%, 30%, and 35%) on the mechanical properties of recycled low density polyethylene (RPE) and mixed with 20 percent weight fraction of virgin polyethylene (MPE) composites was aimed to be investigated. The waste polyethylene was blended with virgin polyethylene and the composites of RPE and MPE were moulded with the addition of rice husk filler using injection moulding machine at a pressure 150MPa and temperature 160oC. The composites were cut into specified dimensions and mechanical properties were conducted on them. Tensile strength increased up to 10 percent weight fraction of rice husk filler in the composites and later decreased above 10 percent filler loading. Tensile modulus, flexural strength and modulus, and Brinell hardness increases with increased filler loading, but impact strength decreases with increased in filler loading. The rice husk filler loading had significant effect (p < 0.05) on the mechanical properties of MPE composite compared with RPE composite which indicated that rice husk filler may be used for reinforcement of Polyethylene.
