Epoxy has versatile industrial applications due to its brilliant characteristics, but on the other hand due to the delamination, brittleness, low toughness of epoxy limited its usage. These constraints of epoxy can get over by inclusion with the help of reinforcement before their industrial and aerospace application. In recent days, glass fiber reinforced composites are in demand as structural materials as well as aerospace parts due to low density. Authors have presented the last ten years review articles on different glass fiber composites. The interest of the present study is the focus on the mechanical properties of epoxy hybrid composite, made up of glass fibers, and reinforced with fly ash. Experimental data has been shown by picking various ratios of glass fiber (E-300, MAT form) with epoxy resins and with different composition of fly ash reinforced that fly ash significantly increases hardness as well as compressive strength in epoxy composite.
