| 摘要 |
A ceramic armor is disclosed that utilizes a titanium frame assembly surrounding monolithic ceramic tiles combined with aluminum pressure infiltration. The aluminum pressure infiltration serves to “wet” the ceramic, bonding the ceramic to the titanium frame on the top, bottom, sides and interior of the frame assembly. After aluminum pressure infiltration at high temperature followed by cooling, this combination creates compressive stress in all directions surrounding the ceramic thereby enhancing localization of a blast/projectile hit to enhance the armors effectiveness. Even after damage due to a projectile hit, adjacent tiles retain their structural integrity, residual stress, and bond to the frame assembly. |

1. A ceramic armor comprising:
a plurality of dense ceramic core tiles having a plurality of side surfaces, each of said plurality of dense ceramic core tiles having a top and bottom surface; an interconnected frame assembly, said frame assembly including an interior having a plurality of cells, said cells including a plurality of walls, said tiles disposed within said plurality of cells, said plurality of walls and said plurality of tile side surfaces having a gap therebetween of at least 0.0005 inches, said frame assembly further including side rails surrounding said plurality of cells, said side rails and said periphery of said plurality of cells having a gap therebetween of at least 0.0005 inches; at least one top plate and at least one backing plate having a top and bottom surface, said top plate bottom surface and said top surface of said plurality of dense ceramic core tiles having a gap therebetween of at least 0.0005 inches, said backing plate top surface and said bottom surface of said plurality of dense ceramic core tiles having a gap therebetween of at least 0.0005 inches; a metallic material encapsulating said plurality of cells, said top plate said backing plate, and said side rails, said metallic material infiltrating said gap between said plurality of said tile side surfaces and said plurality of cell walls forming a bond therebetween, infiltrating said gap between said side rails and said periphery of said plurality of cells forming a bond therebetween, infiltrating said gap between said top plate bottom surface and said top surface of said plurality of dense ceramic core tiles forming a bond therebetween, and infiltrating said gap between said backing plate top surface and said bottom surface of said plurality of dense ceramic core tiles forming a bond therebetween, wherein the CTE of said frame assembly, said top plate and said backing plate, is greater than the CTE of said plurality of said ceramic core tiles, said plurality of dense ceramic core tiles being under compressive stress. |
