Abstract
A steel-polymer composite structure having an aluminum polymer anchoring layer, wherein the composite structure consists of—a first sub-structure which consists solely of steel,—a second sub-structure which consists solely of aluminum or an aluminum alloy and which adjoins at least sub-regions of the first sub-structure and is applied thereon, and—a third sub-structure which consists solely of a polymer, fiber-polymer composite, or polymer particle composite and which adjoins at least sub-regions of the second sub-structure and is applied thereon, wherein—a layer structure which runs from the center of the first sub-structure at least in one direction is made of the first, second, and third sub-structure such that the first sub-structure made of steel is at least partly covered by and/or is connected to the second sub-structure made of aluminum or an aluminum alloy, and the second sub-structure is at least partly covered by and/or is connected to the third sub-structure. The invention additionally relates to a method for etching anchoring structures.
