Abstract: Described herein is a process for producing polyurethane sandwich moldings including at least one core layer and at least one reinforcing fiber layer, where (i) at least one reinforcing fiber layer is applied onto a core layer and a moisture-curing polyurethane adhesive is applied to a reinforcing fiber layer, (ii) the part from (i) is placed into a mold and pressed in the mold and the moisture-curing polyurethane adhesive is cured, and (iii) the molding from (ii) is removed from the mold and optionally subjected to further operations, where the moisture-curing polyurethane adhesive is applied before or after application of the reinforcing fiber layer onto the at least one core layer and for the curing the moisture-curing polyurethane adhesive is brought into contact with water or with a solution comprising water. Also described herein are a polyurethane sandwich molding obtainable by such a process and a method of using a polyurethane sandwich molding in vehicles.
