Abstract
Abstract Composite ceramic armor (10) and a method for making the armor are disclosed as incorporating a plurality of plate-shaped ceramic tiles (12) and cloth (18) wrapped around each tile over each surface (14) and side (16) thereof with a synthetic resin matrix (20) permeating the cloth to encapsulate the tiles such that the resin matrix defines oppositely facing surfaces (22) and a plurality of sides (24) from which the ceramic tiles are spaced by the cloth. The tiles (12) are preferably rectangular and the cloth (18) preferably includes a pair of strips (26,28) wrapped around each tile in perpendicular directions to each other. Woven cloth is preferably utilized and is most preferably made from glass fibers or polyamide plastic fibers such as Kevlar.
