COMPONENTS MADE FROM CONTINUOUS-FIBRE-REINFORCED POLYAMIDE MOULDING COMPOSITIONS AND RUBBER, AND A PROCESS FOR THEIR PREPARATION

摘要

23443-434 A composite article made from at least two moulded materials A and B firmly bonded together. The material A is composed of a matrix of polyamide or of a polyamide-containing moulding composition and of a continuous, fibrous reinforcement. The material B is the rubber obtained by peroxidic vulcanization of a rubber composition comprising 100 parts by weight of a rubber having carboxyl or anhydride functional groups, 10 to 300 parts by weight of fillers, 1 to 10 parts by weight of peroxidic vulcanizing agents, 0 to 4 parts by weight of vulcanization activators and 0 to 150 parts by weight of plasticizers. The materials are bonded by applying the rubber composition to material A and vulcanizing it without the use of coupling agents. The articles have good vibration-damping characteristics and are suitable for any application in which a combination of high rigidity and high elasticity is required, such as in peripheral protective elements in vehicle construction or in armour-plating.
