摘要：
A skeletal layer of a first polymeric material, consisting of two parallel plates interconnected by spaced-apart webs, is overlain on at least one plate surface by a reinforcing layer of a more wear-resistant or otherwise protective second polymeric material, possibly with interposition of an equalizing layer of a third polymeric material. The reinforcing layer may carry a lower-melting coating of a fourth polymeric material serving to hold a covering such as a textile fabric in position thereon. The voids of the skeletal layer may be filled with foam plastic. The composite panel can be formed by joint extrusion of all polymeric layers and can be subjected to subsequent deformation under heat and pressure into a shaped body.
