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.

In the present study, traditional and hybrid composites were prepared by Hand lay-up
molding and investigated. The composites constituents were unsaturated polyester resin
as the matrix, 3% and 6% volume fractions of carbon fibers as reinforcement and 3% of
Al2O3, Al, Cement and local Gypsum (calcium sulfate anhydrate CaSO4) as filler
particles. The investigated physical properties were density, porosity while the
mechanical properties were tensile properties, bending modulus of elasticity. The
experimental results showed that increased volume fraction of carbon fibers to (6%) led
to increase in physical properties (density, porosity. As for the mechanical properties,
carbon fiber composites and (3% carbon fibers/Al2O3)-contained hybrid composites gave
the higher tensile and fracture strength, carbon fiber then gypsum composites gave the
higher bending modulus.
