Increase safety and comfort demands bring more weight into the vehicle. Strong motors lead to rising fuel consumptions. Lightweight construction is a key technology to counteract this development to ensure furthermore the production of safe, comfortable and high performance cars while protecting resources and environment at the same time. Higher process stability, improved material usage and general shortening of process chains are the most important tasks of Fraunhofer IWU. The requirements towards the future car ask for lightweight construction concepts, in which materials, design and manufacturing process harmonize optimally. The usage of lightweight materials is only reasonable when their mechanical characteristics such as stability, stiffness and temperature resistance are better than classic steel. The same is true for the material and production costs. Therefore, Fraunhofer IWU researches on forming and joining technologies for the optimum usage of high-strength steels, aluminium, magnesium and fiber composite materials. New forming technologies as press hardening or electromagnetic forming bring the positive effects by resource efficiency and energy save.
