Abstract

The invention relates to a molding tool for the production of components composed of fiber composite materials, in which the molding tool has a fiber composite structure and an electrical resistance heating element, whereby carbon fibers or carbon filaments are embedded into the fiber composite structure of the molding tool in a plastic matrix, close to the shaping surface of the molding tool. Such a molding tool is further developed in that the carbon fibers or carbon filaments in the plastic matrix, close to the shaping surface, essentially determine the mechanical strength of the molding tool, and that the electrical resistance heating element is interconnected in such a manner that at least individual sections of the electrical resistance heating element form an electrical parallel circuit with one another.
