Abstract

A laminate consists of a layer A of a polyolefin, reinforced with from 10 to 50% of glass fiber mats, and a metal layer D, which are bonded to one another by means of a mechanically adhesion-promoting layer B and an adhesive layer C. The adhesive is a thermoplastic polyurethane elastomer, preferably having a melting range of from 110.degree. to 250.degree. C. The laminates are used as automobile components, and as housings and containers.
