Abstract: The present work describes the effect of filler on mechanical properties of glass/epoxy composite. E-glass fibre is used as reinforcement, embedded in Huntsman Ly 556 epoxy matrix using Ht 972 as hardener and Nano clay as filler in preparation of the composite using the hand lay-up technique. The effects of fillers on mechanical properties were studied by conducting the tests. With addition of filler, Tensile, Flexural, Impact and Fracture toughness increases. The highest values of tensile, flexural, impact and fracture toughness were observed at a filler percentage of 2.5 wt%. The mechanical property of E-glass/epoxy composites decreases at 5 wt%. To obtain the maximum strength in composite, the filler percentage in the composite to be kept within 5 wt%.
Keywords: E-glass fibre, fillers, mechanical properties, fracture toughness, epoxy resin
