Abstract: A thermoplastic multilayer composite comprising at least one first layer comprising a fluoropolymer, and also of at least one other second layer, at least some regions of which have direct contact with the first layer. This multilayer composite achieves surprisingly excellent adhesion between the two layers, because the second layer is comprising polyamide-polyamine copolymers. This second layer may particularly advantageously be used as an adhesion-promoter layer in relation to a further, third layer, which, by way of example, is comprising polyamide. In the form of a hollow body or hollow profile, this structure comprising at least 3 layers can preferably be used as fuel piping in the motor vehicle sector.

Furthermore, the present invention relates to a process for making such a thermoplastic multilayer composite as well as to the use of such a thermoplastic multilayer composite as a tubing in particular for fuels. In particular in the context of the use as a tubing for fuels the proposed multiplayer structure shows to be surprisingly resistant against petrol comprising peroxide while at the same time having a simple structure, if the inner layer (1) is based on a mixture of different polyamide homopolymers.
