Abstract
The invention relates to a method for joining a composite sheet to a metallic substrate, wherein the composite sheet has at least one metallic top layer and at least one non-metallic layer which consists of a plastic material, wherein an opening is introduced into the composite sheet, and wherein at least one joining element is provided which is inserted into the opening of the composite sheet. A method for joining a composite sheet to a metallic substrate with process reliability and of specifying a corresponding structure is achieved by forming the joining element as a metallic sleeve, wherein the metallic sleeve is deformed, so that it joins together with the composite sheet in a form-fit and force-fit manner, and wherein the metallic sleeve is firmly bonded to the substrate with the end pointing towards the substrate using a filler material, wherein the filler material is arranged inside the sleeve.
