To Study the Effect of Fillers on the Glass Fiber Reinforced Composites
Rafah A.Nasif
Abstract

This study was carried out to investigated the effect of ceramic fillers (aluminum oxide Al2O3 and titania TiO2 ) and industrial wastes (red mud and copper slag) with weight fraction (10% wt)on the mechanical properties of composite material consist of epoxy reinforced with glass fiber with weight fraction (40/50)%wt .Some tests are carried out like: impact strength, tensile strength and harness and results have been compared with composite material reinforced only with glass fiber (50/50)%wt . The results show that the composite reinforced with TiO2 had higher value of impact strength and lowest value of tensile strength compared with other composites, while composite material reinforced only with glass fiber had higher value of tensile strength. Also, it can be seen that all hybrid composites have hardness values higher than that of composite material reinforced only with glass fiber and the highest hardness value was for the composites material reinforced with Al2O3.
