The invention concerns a composite comprising an elastomer portion and a plastic portion rigidly connected to this elastomer portion, an anti-vibration part incorporating this composite and a method of producing the latter. This composite comprises an elastomer portion consisting of a vulcanised rubber composition made from at least one diene elastomer and a plastic portion that is made from at least one polyamide and that is rigidly connected to the elastomer portion by co-vulcanisation, forming an adherent plastic-elastomer interface free of adhesive. According to the invention, said interface comprises covalent bonds that are produced by a Michael reaction between a polyether amine-type nucleophile Michael donor that is included in the plastic portion and an α,&bgr;-unsaturated carbonyl compound-type electrophile Michael acceptor that is included in the elastomer portion. |
