The use of a solid, foamable plastic, for example poly(meth)acrylimide (PMI), polyvinyl chloride (PVC), polyurethane (PU) or poly(meth)acrylate (PMMA), permits the production of a plastics foam composite moulding which is in essence homogeneous and which, in the course of the foaming process at about 200 degrees Celsius, forms a stable mechanical bond with an outer layer or a plurality of outer layers or with a plurality of identical or different outer layers. |
