Self-supporting molded component for automotive vehicles

Forming tool comprising a shaped structure that is porous and air-permeable and that is made from a reactive resin and at least one inert filler.

Process for the production of a forming tool from reactive resins with

A process for joining abutting thermoplastic synthetic resin foam structures by a strip which covers a junction zone formed between the foam structures including the steps of pressing a metal strip heated to above the softening point and or the melting temperature of the synthetic resin foam under slight pressure onto the junction zone and then allowing the metal strip to cool. In this manner, a bond is formed between the foam structures and the metal strip.
