Polymer Matrix Composites (PMC) are gaining more importance compared to the monolithical materials as being more reliable and cheap. Polymer matrix composites finding applications from household to engineering approach. With the advancement of PMC‟s their properties can be increased by the addition of one more fiber made as hybrid composite which boosts the property of PMCs where a single fiber composite lags. In our project we have chosen rice husk as the major reinforcement and aramid as an additional fiber to improve the mechanical property of polymer composite with vinyl ester as the base material prepared by hand lay-up process according to ASTM standards. Test specimens are prepared with different weight fractions of rice-husk at the optimization point of tensile test a small percentage(3%,5%,7%) of aramid are added and tests were conducted and the improvement in mechanical properties (tensile strength and flexural strength) of the hybrid composite material is observed.
