Abstract

Locally reinforced sheet metal parts can be used as a contribution to lightweight construction. They can also help to enable a load-adapted way of constructing parts or machines. One possibility to produce locally reinforced parts is the Bonded Blanks technology, where base sheets are locally joined with reinforcement-sheets by adhesive bonding in two stages and formed together in just one forming operation. The joining-step of the base sheet with its reinforcing sheet is followed by forming of this bonded double layer by deep drawing. The final curing process is initiated by heat-treatment during drying-step in cataphoretic coating. This paper deals with the investigation on the effects of hydromechanically deep-drawn parts with local reinforcements produced with the Bonded Blanks technology. Different sheet metal materials along with different adhesives are tested.
