摘要：
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.
