Abstract: Current processes for the formation of hybrid composite sandwich structures are expensive, often result in weak unsound products, require time and labor intensive operations and are not readily adaptable for custom design work. These and other problems are solved by relatively simple and inexpensive process producing hybrid composite sandwiched structures which includes placing core materials (24) sandwiched by multiple layers including at least one ceramic layer (46) or metallic layer (38) and having polymeric films (32, 34, 40, 42) positioned between substantially all the layers in a mold cavity (18). When the contents of the mold cavity (18) are heated to consolidate this structure, the polymeric films (32, 34, 40, 42) melt and act as an adhesive between the layers of the structure formed.
