PROBLEM TO BE SOLVED: To provide a desirable adhesion to a layer of fluorinated polymer, by using a polyamide-polyamine copolymer as an adhesive layer. SOLUTION: A thermoplastic multilayer composite (4) comprises at least a first layer (1) of a fluorinated polymer and at least one different second layer (2) of which at least some area directly comes into contact to the first layer. The multilayer composite achieves a surprisingly good adhesion between two layers (1) and (2), since the second layer (2) consists of a polyamide-polyamine copolymer. The second layer (2) can be used in particular favorably, for example, as an adhesion enhancing layer to an additional third layer (3) of polyamide. The structure with at least three layers can be used, in a form of a hollow body or a hollow member, preferably as a fuel pipe in automotive sectors. COPYRIGHT: (C)2005,JPO&NCIPI
