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