Abstract: The invention relates to temperature-stable rigid foams which can be cold formed and have a density of 0 to 100 kg/m (according to DIN 53420), an elongation at break (according to DIN 53430) of 12 to 35%, a percentage of open cells (according to DIN ISO 4590-86) of 51% to 98% and a storage module of the foam (according to DIN EN ISO 6721 B:1996-12) in the temperature range of 60 DEG to 190 DEG C of, on average, greater or equal 0.1 MPa, and to composite materials produced with said foams.

Abstract: The present disclosure relates to a method for producing composite materials containing as a first layer a foamed thermoplastic support and as a second layer polyurethane (PU), the resulting composite materials being characterized by improved foam adhesion, wherein (i) a foamed polycarbonate molding composition is produced by injection molding using chemical or physical foaming techniques, and (ii) the polyurethane reaction system is applied on top and allowed to cure. The disclosure also provides the composite systems produced by this method and their use as a component, in particular in the automotive sector.
