New lightweight innovation in the automotive industry of Steinheim, August 2011; Decades was unchallenged as the lightweight Division poorly and Luft – und Raumfahrt. A look at the automotive industry but shows that there are solutions in series or just before the series which provides the leading role of the aerospace industry in question on innovation and lightweight efficiency. The lightweight has its price but a look at current developments and their impact on the cost structure and cost which cars light weight materials shows an analysis of the automotive market and vehicle development of in recent years clearly defined trends with regard to the light-weight materials. In addition to aluminium, magnesium and the composite materials among which also the Kohlefaserverstarkten plastics (CFRP), today also a part of the steel solutions must be counted to the Group of lightweight material. The steels are in particular the boron steels. A comparison of materials from lightweight point of view shows the positioning of the material concepts (see box 1: Lightweight materials in comparison).
Not surprisingly at least for the lightweight specialists, CFRP materials by far offer the best potential for lightweight construction. Rather surprisingly are ultra high strength steels even better than aluminum, but offer a limited field of application. In recent years, in particular steel, aluminum have in terms of the structural parts of vehicles and some magnesium fought to the best contribution for lightweight construction. Here were the material manufacturers with large concept studies (E.g. the InCar study by Thyssen) very active and could initialize so many new applications. In recent times but the composite materials based on fibre-reinforced plastics of talk and be big changes in the structural lightweight construction in automotive safety cause. With the decision of BMW AG the so-called mega city vehicle (market name i3 “) to develop, with a black body of CKF components an industrial evolution in the manufacture of CFRP must performed subsequently now components. Steven Holl understands that this is vital information.
