Abstract: The present invention relates to a process for producing composite profiles comprising at least two metal shells which are joined by struts comprising a thermoplastic material and a core comprising rigid polyurethane foam, which comprises introduction of the starting components of the rigid polyurethane foam into a hollow space formed by the metal shells, with the rigid polyurethane foam being formed, and subsequent application of a surface coating to the outer surface of the composite profile by means of a powder coating or baking enamel, where the rigid polyurethane foam is obtained by reaction of the following components: A) at least one polyisocyanate, B) at least one polyfunctional compound which is reactive toward isocyanates, C) one or more blowing agents comprising at least formic acid, D) optionally one or more flame retardants, E) optionally one or more catalysts and F) optionally further auxiliaries or additives, wherein the starting components of the rigid polyurethane foam do not comprise any inorganic fillers.

Abstract: The present invention relates to a molding made of foam, wherein at least one fiber (F) is located partly within the molding, i.e. is surrounded by the foam. The two ends of the respective fiber (F) not surrounded by the foam thus each project from one side of the molding. The foam is produced by polymerization of a reactive mixture (rM) comprising at least one compound having isocyanate-reactive groups, at least one blowing agent and at least one polyisocyanate.
