APPENDIX
1. A method of producing a composite component with a foamed
surface, which comprises the steps of:
placing a substrate part having a surface to be coated into a mold;
applying a layer of an unfoamed or merely pre-foamed, foamable
material to the surface of the substrate part at a first
temperature; and
expanding the foamable material at a second temperature higher
than the first temperature, with at least one expanding aid
selected from the group consisting of a chemical blowing agent, a
blowing agent mixture, and microspheres, such that the
foamed material in an 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.
