Optimization of joining techniques for multi-material constructions in body making

The European Automobile Industry has committed themselves to save resources and to minimize the carbon-dioxide emissions. Therefore they decided to reduce the consumption of all their sold armadas since 1995 until 2008 by about 25 %. At this they use aspects of lightweight construction, besides methods to engine optimization and fuel economy. This article from University Paderborn, Daimler-Chrysler, Porsche and Volkswagen deals with targets and results of a project financed by the Federal Ministry of Education and Research (BMBF) to optimize joining techniques of multi-material constructions with steel, aluminum and plastics.
