Process for the production of composite sheet bodies which are suitable as self-supporting components in automobiles |
摘要 |
The present invention relates to a process for the production of composite sheet bodies by back-foaming a flexible facing with a polyurethane foam forming reaction mixture. This polyurethane foam is characterized by a density of less than 300 g/l, preferably from 20 to 150 g/l, and optionally contains isocyanurate groups. Suitable flexible facings include those having a thickness of less than 10 mm, preferably less than 2 mm. This composite bodies produced by this process are suitable for use in the automobile sector as self-supporting components. Conventional stiffening elements are not necessary to produce these self-supporting composite bodies.
