The matrix was polypropylene (PP), and the reinforcements were jute fiber, kenaf powder or rice husk powder. The addition amount of reinforcements were 20 to 40 wt%. In addition, the jute fiber was modified by silane coupling agent (3-Aminopropyltriethoxysilane), and maleic anhydride grafted polypropylene (MAPP) was added as compatibilizer to improve the compatibility between reinforcements and PP, then enhanced the mechanical and thermal properties of the composites. The results reveal that the composites containing 30wt% of jute fiber/kenaf powder possessed the best properties. Moreover, the composites containing 30wt% of jute fiber/rice husk powder were prepared and compared with the jute fiber/kenaf powder ones. The results reveal that the higher heat distortion temperature (about 150.90 ~ 153.05 ℃) were obtained when the ratio of jute fiber and kenaf powder is 1: 3. However, the heat distortion temperatures of jute fiber/rice husk powder composites were increased with increasing content of jute fiber. The tensile and impact strengths of the composites could be increased about 46.63% and 61.86% as compared with those of pure PP. The results of thermal analysis reveal that the heat resistance of the PP was improved by the addition of the reinforcements. Microscopic analysis indicate that the dispersion of jute fiber in the matrix was well when the composites containing 30wt% of reinforcements. As well as enhancing the mechanical properties and thermal stability, the reinforced composites are more environmentally friendly than the artificial additive-reinforced ones. The waste from the kenaf and rice husk is effectively reduced and re-used, and the cost of materials can be reduced.
