CA 2082763

A novel thermoplastic multilayer composite is disclosed comprising a layer of a moulding composition based on a polyamide and intimately bonded to a layer of a moulding composition based on a mixture of from 98 to 60% by weight of a partially crystalline polyester and 2 to 40% by weight of a compound containing epoxy groups. The multilayer composite according to the invention have a good mechanical resistance and a good barrier action against diffusion of chemical agents, solvents and fuels. Since the two layers are intimately bonded one to another, no shearing or delamination of the layers occur during thermal expansion or bending. The multilayer composites according to the invention may be used for manufacturing of construction components, in electrical, mechanical and car industries or as foodstuffs packaging films.
