Lightweight composite armor

Abstract

A lightweight composite armor including an integrally formed matrix block is disclosed. The matrix block includes a generally planar back, a plurality of intersecting ridges extending from the front of the planar back, and fillets provided at the junctures between the planar back and the ridges and at the juncture between the ridges. The matrix block thus forms a pattern of open topped cells. An energy absorbing ceramic body is located in each cell. Individual front plates sized to fit in the open top of each associated cell in mating contact with the ceramic body and provided with upstanding flanges around the periphery thereof are also provided. A weld around the periphery of the front plates between the flanges and associated tops of the ridges is provided. In this manner, impact by a projectile on one of these front plates substantially limits any damage to that one front plate and the underlying ceramic body leaving the remaining armor substantially undamaged. In accordance with the preferred embodiment, each ceramic body includes a concave surface adjacent the mating front plate. In addition, small gaps which exist between the cells and the ceramic bodies are filled with a ceramic-based grout. A polymer impregnated fabric is also provided at the rear of the planar back as desired. Ridges at the planar back can also be provided for stiffening the planar back.
