Abstract

Components made from at least two molded materials A and B which are firmly bonded together, and in which PA0 a) the molded material A is composed of a matrix of polyamide or of a polyamide-containing molding composition and of a continuous, fibrous reinforcement embedded therein, and PA0 b) the molded material B is the rubber obtained after peroxidic vulcanization of a rubber composition which is applied to A, the rubber composition containing the following components: PA1 i) about 100 parts by weight of a rubber having carboxyl or anhydride functional groups; PA1 ii) about 10 to 300 parts by weight of fillers; and PA1 iii) about 1 to 10 parts by weight of peroxidic vulcanizing agents.
