ABSTRACT:
A process for fabricating high density aluminum modified boron carbide compositions comprising the steps of blending specific quantities of powdered boron carbide and powdered aluminum together with a small quantity of temporary organic binder, preforming this mixture to the desired shape with high pressure at room temperature, followed by final densification of the finished product at a temperature below the sintering temperature of boron carbide and at a pressure as low as 500 psi. The resulting compositions are near theoretical density and possess a degree and type of strength which make them well suited as protective armor against penetration by ballistic projectiles.
