Abstract
A ballistic resistant panel which is formed from a ceramic layer and a plurality of fibrous backing layers. A first fibrous backing layer is adjacent to the ceramic layer, and a second fibrous backing layer is adjacent to the first fibrous backing layer. Each of the fibrous backing layers are formed from a network of high tenacity fibers, but the fibers of each of the backing layers have a different composition. Preferably, the first fibrous layer is stiffer than the second fibrous layer. The panel has a ballistic resistance which is substantially equivalent to or higher than the ballistic resistance of a comparable ceramic panel construction that has only a single fibrous layer of the same type of high tenacity fibers as are in the first and second fibrous backing layers, for substantially the same areal density.
