Abstract: In this study, polymeric composite material were prepared a by hand- layup technique from epoxy resin as a matrix and Aluminum powder with particle size 7.1228m as fillers with different weight percentage (0, 0.15, 0.25, 0.35, and 0.45) to resin. Mechanical properties such as three point bending and Hardness testing were investigated. The results show the flexural modulus (E) increase with increasing Aluminum percentage and it have maximum values of (8.1638MPa) for 45 % Aluminum. Flexural strength, Fracture stress and Deflection decreases with increasing of the Aluminum percentages compared with pure Epoxy, except the ratio 15 %, the Yield Points for all Aluminum percentage increasing with increasing ratio fillers. The results of hardness test show increase hardness with Aluminum concentration increase.
