Abstract
Current processes for the formation of hybrid composite sandwich structures are expensive, often result in weak unsound products, require time and labor intensive secondary operations and are not readily adaptable for custom design work. These and other problems are solved by a relatively simple and inexpensive process producing hybrid composite sandwiched structures which includes placing core materials 24 sandwiched by multiples 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.
