The invention relates to a heat-curable binding-agent composition based on rubbers and vulcanizing agents containing natural and synthetic and/or olefinic double bonds. Said compositions can be formed into multi-layer, flat shaped bodies by extrusion onto reinforcing elements, which are in the form of films or flat structures containing fibres. Multi-layer, flat shaped bodies of this type are suitable for use as reinforcing and stiffening elements that are devoid of the conventional low-molecular epoxy resins and/or volatile diisocyanates of polyurethane binding agents. Said shaped bodies are suitable for stiffening or reinforcing thin-walled, flat metal or plastic components, in particular in the automotive industry.
L'invention concerne une composition d'agents liants thermodurcissable à base de caoutchoucs et d'agents de vulcanisation naturels ou synthétiques, contenant des liaisons doubles oléfiniques. La composition selon l'invention peut être façonnée en corps moulés plans à plusieurs couches par extrusion sur des agents de renforcement sous forme de film ou de structures planes contenant des fibres. De tels corps moulés plans à plusieurs couches conviennent comme agents de renforcement et de raidissement exempts des résines époxy de faible poids moléculaire traditionnelles ou des diisocyanates volatils d'agents liants polyuréthanne. Ces corps moulés conviennent au raidissement ou au renforcement de composants plans à parois minces en métal ou en plastique, notamment dans l'industrie automobile.
