Method of producing a composite component with a foamed surface

Abstract

A composite component is produced with a foamed surface. A substrate part having a surface to be coated is placed into a mold, a layer of an unfoamed or merely pre-foamed, foamable material is applied to the surface of the substrate part at a first temperature, and the foamable material is expanded at a second temperature or a sequence of temperatures that are higher than the first temperature. The expansion is effected with a chemical blowing agent or a blowing agent mixture, so that the foamable material in the expanded state fills an intermediate space between the surface of the substrate part and a molding surface of the mold and, on the one hand, bonds with the surface of the substrate part and, on the other hand, comes to bear against the molding surface.
