Abstract
A roof module for a motor vehicle comprises an RTM frame and a Class-A covering layer, which at least partially covers the frame and is made of polyurethane. A method for manufacturing a roof module comprises the following steps: Initially, a fiber mat is put into a first mold. Then, a reactive resin system is introduced into the closed mold and the resin cures, so that a blank is formed. The blank is put into a second mold, into which subsequently polyurethane is introduced in the open condition. The polyurethane expands, wherein it at least partially forms a Class-A surface.
