Patent ID: 8176830

Claim:
A method for the fabrication of a multi-layer ballistic device including at least a supporting structure and a plate hard layer comprising: 1) wrapping at least one suitable plate in a thin plastic sheet; 2) fabricating a pair of molds from a blend of hydro-stone powder, water and fiber strands and pouring it over the plate using the plate as the shape of the cavity; 3) curing the mold thus formed at a temperature in excess of 21° C. for at least one hour; 4) placing multiple layers of ballistic resistant fabrics into the mold with the plate; 5) heating the mold containing said fabrics and said plates to a temperature of between 120 and 150° C. and holding such temperature for 15 to 60 minutes; and 6) cooling said mold to a temperature less than 27° C.
