Abstract: Rice husk ash (RHA) reinforced polyester composites containing 5% to 20% rice husk ash with respect to the weight of unsaturated polyester resin have been prepared by compression molding. Different physical and mechanical properties such as water absorption, compressive strength, elastic modulus, flexural strength, hardness of rice husk ash composites were investigated by standard methods. Universal testing machine (UTM), Leebrebound hardness tester, Vickers hardness tester were used to characterize the Rice husk ash polyester composites. The effects of amount of rice husk ash in rice husk ash polyester composite on different mechanical and thermal properties of rice husk ash composites were studied in detail. The results indicated that amount of reinforcing agent plays a vital role in the properties of rice husk ash composites.
