This paper study the tensile and flexural properties of composites materials made from rice husk as filler particles and epoxy resin as matrix . The tensile and flexural tests of composites based on rice husk filler particles at three different filler contents 5 wt.%, 10 wt.%, and 15 wt.% , were carried out using universal testing machine according to ASTM D638 and ASTM D790 respectively. Experimental results showed that tensile and flexural properties of the composites constraint increased with the increase of the filler particle content. The composite materials nearly linear behavior and sharp fracture for tensile and slight non-linear behavior and sharp fracture for flexural testing. The relation between stress and content of filler for tensile and flexural tests were found to be linear . Concerning the relation between the modulus and percentage of filler for tensile and flexural tests, it was found to be a quadratic relation. The same behavior was observed for the strain versus percentage of filler for tensile and flexural tests.
Key words: epoxy resin ; polymer matrix ; rice husk; composite materials ; tensile properties ; flexural properties.
