摘要：
A composite element made from a preform of fiber-reinforced plastic material arranged around a core with a multi-layer thermoplastic foil between the preform and the core and a method for fabrication of such a composite element. At least one of the layers of said multi-layer thermoplastic foil has a different melting temperature from the melting temperature of at least one of the other layers.
