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.
Claims16
A method for forming an impact resistant clad composite armor having a ceramic core, said method comprising the steps of:
- surrounding said ceramic core with powder metal;
- cold isostatically pressing the powder metal surrounding said ceramic core to a high initial density to form an armor compact;
- and
- vacuum sintering said armor compact to further densify the powder metal and form said composite armor.
An impact resistant clad composite armor comprising:
- a ceramic core;
- and
- a layer of metal surrounding said ceramic core and bonded to said ceramic core, said layer of metal being formed by cold isostatically pressing powder metal surrounding said ceramic core to a high initial density followed by vacuum sintering.
An impact resistant clad composite armor comprising:
- a ceramic core;
- and
- a layer of metal of surrounding said ceramic core and bonded to said ceramic core, said layer of metal being comprised of dense, cold-compacted, sintered powdered metal, said metal being selected from the group consisting of aluminum alloys, commercially pure titanium, and titanium alloys.
