Abstract

The invention relates to an extrusion-blow-molded fuel tank () of thermoplastic material comprising a tank wall of a composite of various layers obtained in various production operations, at least one first layer comprising at least one shell-shaped supporting shell () and a second layer of a thermoplastic material forming an adhesive bond with the supporting shell (), and the supporting shell () having a greater strength than the second layer. The supporting shell () forms an inner layer of the tank and the second layer forms an outer skin of the tank, two supporting shells within the tank forming a supporting cage or a supporting housing.
