Abstract:
1. A method of making ceramic armor, comprising: (a) providing a base plate, a frame having an open center, and a cover plate, together defining an internal chamber; (b) inserting a piece of ceramic material into said chamber, said ceramic material being closely received within said chamber, said base plate, frame, cover plate, and ceramic material together defining an assembly; (c) said metallic material having a coefficient of thermal expansion greater than a coefficient of thermal expansion of said ceramic material; (d) placing said assembly into a graphite die, said die having inner walls coated with Titanium foil, said assembly having outer surfaces engaging said foil, said foil separating said outer surfaces from said walls of said die; (e) placing said die with said assembly therein into a hot press consisting of a furnace located within a sealed chamber; (f) conducting a hot pressing procedure on said assembly under controlled parameters of temperature, pressure and atmosphere until said metallic material is plastically deformed around said ceramic material.
