Abstract
Abstract Armor materials are disclosed which include compositions comprising the components: (1) a high strength chemically bonded ceramic, and (2) an additional constituent comprising (a) fibers that increase the fracture toughness and multi-hit capability of the armor materials, and/or (b) hard aggregates which blunt, deflect and/or erode penetrators that strike the armor. The disclosed armor materials also include compositions which utilize component (1) or a mixture of components of (1) and (2) as a matrix in multi-component systems. The multi-component systems comprise elements or segments of various shapes, sizes and materials.
