A composite for protection against armor-piercing projectiles is disclosed. The composite can be a ceramic composite which may be utilized alone or with other materials, e.g., a metallic or plastic base or substrate layer. Composites of AlN with TiB.sub.2, SiC, B.sub.4 C or their mixtures are utilized. These ceramic composites can be prepared by hot pressing, reaction hot pressing, hot isostatic pressing or pressureless sintering. The composite may have well dispersed grains for at least one component, which grains can be interconnected with grains of the second component, and the grains may be of a size less than about five microns. The composite in layer form can have a metallic cover layer.
An armor plate layered composite for protection against projectiles and having enhanced resistance to penetration from high kinetic energy projectiles, which armor plate comprises a metal substrate and a surface layer composite ceramic on said substrate of very finely-divided and interconnected grains of TiB.sub.2 and AlN.
An armor plate layered composite for protection against projectiles and having enhanced resistance to penetration from high kinetic energy projectiles, which armor plate comprises a metal substrate and a surface layer composite ceramic on said substrate of AlN in mixture with one or more of TiB.sub.2, SiC or B.sub.4 C, with said surface layer having very finely-divided and interconnected ceramic grains.
