Abstract

In a method of making a body part or chassis part of a motor vehicle, several pre-impregnated fiber materials (prepregs) are stacked on top o one another, with an outermost prepreg intended for attachment to a metallic base body being provided with an adhesive. The stacked prepregs are then shaped into a three-dimensional preform which is then compressed with the base body in a press tool for bonding the preform with the base body and allowing the adhesive to cure, thereby producing a joined structure which is allowed to cure.
