 This paper reports on the influence of rice husk amounts and particle sizes on polypropylene (PP) mechanical and morphological properties. The ground and sieved rice husk was compounded with PP using a twin-screw extruder and the extrudate injected into test specimens. The results from mechanical tests showed that Young's modulus and flexural modulus were considerably increased with higher content and smaller particle size of rice husk without the use of any coupling agent; however, tensile strength, elongation at yield and flexural strength were found to be slightly decreased. In addition, the Young's modulus and flexural modulus depended on both filler particle sizes and contents, whereas the tensile strength, elongatin at break and flexural strength were influenced by the filler volum. The rice husk filler dispersion and interfacial boundary between the filler and the matrix could be observed from scanning electron microscopy (SEM).
