Over the last decade the reduction of fuel consumption and CO2-emission became progressively important in the automotive industry. Beside new drive concepts, lightweight construction is one promising approach to achieve this target. Innovative steel technologies like tailored blanks can be used for lightweight automotive structures. This method offers the benefit of using existing manufacturing processes to achieve required cycle times. However this method offers only limited lightweight potential. In contrast fiber reinforced plastics (FRP) provide a maximum weight reduction because of their excellent specific mechanical properties. Due to a high material price and a low level of automation in manufacturing processes it is currently not possible to supply required quantities for medium- or large-scale production. To solve these problems there are efforts to combine the advantages of both technologies. The basic concept is a reduction of the wall thickness of sheet metal based components and the reinforcement of these structures in heavily stressed areas with FRP. By using these hybrid materials it is possible to combine the stiffness and strength of FRP with ductile behavior of metal. For the automotive industry the resulting hybrid materials can be used for body structures to reduce weight and improve the crash performance. The objective of investigations at ITA is the joining process of metal and FRP. Different treatments of surface are evaluated as well as the use of adhesives to improve the connection of the materials. By enhancing the quality of the joining process the specific properties of both materials can be optimally used and a high lightweight grade can be achieved. Besides the joining properties themselve there are investigations to integrate the hybride materials into automotive production processes. One focus is production within short cycletimes, while the treatment by cathodic dipcoating process (KTL) forms another. Further prospects of investigation are simulation of hybrid structures for damage prediction and specific use of material.
