A method for forming a beading fold in a multi-layer composite material, which has at least one core layer made of a plastics material and at least two cover layers made of a metallic material, provides high process reliability and optimal integrity of the formed multi-layer composite material. In particular, the method provides that, in the region of the beading fold to be formed, the core layer of the composite material is heated at least in portions to a temperature of 180° C. to 300° C. Also described herein is a multi-layer composite material having at least one beading fold, said material comprising at least one core layer made of a plastics material and at least two cover layers made of a metallic material.
Method for forming a beading fold in a multi-layer composite material, which has at least one core layer made of a plastics material and at least two cover layers made of a metallic material, wherein the complete material of the at least one core layer of the composite material is heated to a temperature of 180.degree. C. to 300.degree. C. in a region of the beading fold to be formed to reduce the strength of the plastics material so that the plastics material from the region of the beading fold is partially displaced and the core layer in the region of the bend of the formed beading fold tapers compared to regions outside of the bend of the beading fold.
