The current work involves the development and mechanical characterization of polymer composites prepared by the use of glass fibers and micronized rubber powder fillers reinforced in epoxy matrices. The composites were prepared by keeping weight fraction of matrix as 50% and varied the wt% of the reinforcements using hand layup technique. The results revealed that, 40 wt% of E-Glass and 10 wt% of micronized rubber powder filler reinforced composites yields better mechanical properties.
