Mechanical Properties for Polymer Hybrid Composites Reinforced by Fibers and Particles


The Mechanical properties of hybrid composites based on epoxy resin (ER) filled with metal powders (Al) and Glass fibers (GF) are studied. The specimens are prepared using hand lay-up techniques according to ASTM standard for different volume fractions of fiber, particles& matrix material. Glass fibers (GF) are one of the most useful filler materials in composites, its major use being the manufacture of components in the aerospace, automotive, and leisure industries. The epoxy was reinforced with GF:( metal powders)in the ratio 10%:40%, 20%:30%, 30%:20%, and 40%:10%. It was observed that in the ratio 40%:10% has the maximum(UTS), fracture strength, flexural strength, fracture toughness and hardness increase with the increase of volume fraction of fibers when compared to unfilled epoxy.
