Abstract

In a car fuel tank with a body (12), whose outer wall (19) is made up of a layer of resin. Synthetic, consisting of a multilayer structure, a synthetic resin layer, as well as an inner body layer and an outer hierarchy with a transverse layer (26) interpolated between them, the outer wall (19) is built. From, in order from outside to inside, top surface (20), outer base layer (22), outer adhesion layer (24), transverse barrier (26), inner adhesion layer ( 28), inner baseboard (30) and structural parts (32), structural parts (32) are enhanced to the inner basement (30) by internal welding. Formation of the inner body layer And outer hierarchy
