Abstract
A multilayer composite body includes thermoplastic layers and layers of natural fibers bound with thermoplastic synthetic material. The composite body has at least one reinforcing layer made of an open-cell fabric of melting fibers. The reinforcing layer is penetrated on one or both sides by the melting thermoplastic synthetic material of adjoining natural-fiber layers and is integrated there for reinforcement. The reinforcing layer can also be disposed in addition or only between natural-fiber and pure thermoplastic layers or between thermoplastic layers. Such a composite body has excellent mechanical properties, in particular with regard to bending stress and impact resistance.
