AB  - In this research, different compositions of composite materials based on epoxy resin and four different fillers were prepared and all mechanical characteristics were investigated to reach a composite material having high resistance to impact by high kinetics energy projectiles which is required in the production of bulletproof jackets and also in cassette shields of explosive reactive armors to protect tanks. This composite material is usually applied as layers with other polymeric fibers such as carbon fibers and Kevlar (polyamide) sheets. The used epoxy consists of Epon as linear epoxy and tertiary amine as hardener. The used fillers are carbon black, magnesium carbonate, wood flour and sand. The pure thermoset epoxy (without filler) which gives the highest different mechanical properties is based on 10:5 by weight (linear Epon/Hardener). The composition which gave the highest resistance to impact by high kinetics energy projectiles was epoxy resin containing 15% by weight wood flour where the resistance to impact was increased by 32% when compared with the pure epoxy.
