Abstract
Impact resistant clad composite armor and method for forming such armor. The impact resistant clad composite armor includes a ceramic core, and a layer of metal surrounding the ceramic material and bonded to the ceramic core. The metal layer is formed by cold isostatically pressing powder metal surrounding the ceramic core to a high initial density followed by vacuum sintering. The composite armor may be hot isostatically pressed to densify the powder metal to approximately 99% full density.
