Abstract
An impact resistant clad composite armor which includes a ceramic core, and a layer of bulk amorphous alloy surrounding the ceramic core and preferably bonded chemically to the ceramic core and a method of manufacturing such armor is provided.
Claims15
A method of manufacturing a ceramic armor comprising:
- providing a ceramic core;
- providing a quantity of a molten amorphous alloy, said amorphous alloy having a yield strength of at least 1.6 GPa and an elastic strain limit of at last 1.2%;
- and
- forming a metallic layer encapsulating said ceramic core from the amorphous alloy such that the metallic layer places the ceramic core under a compressive stress of at least 400 MPa, wherein at least a portion of the metallic layer formed from the amorphous alloy has a thickness of about 0.5 mm or more.
