Abstract: A reinforced silicone rubber mold composite is formed by bonding a silicone mold member to a rigid laminated member. The silicone rubber mold member is cast to conform to a desired pattern and its back surface is bonded to a flexible open-celled foam by means of a layer of the silicone rubber being impregnated into a layer of open cells of the foam which are adjacent to the back surface of the silicone rubber mold member. The laminated member consists of the flexible open-celled foam having the layer of open cells impregnated by the silicone rubber and the remaining open cells impregnated by a cured epoxy resin.
