Lightweight body design using fibre-reinforced plastics (FRP) is appropriate in car manufacturing if the drop in weight results in a reduction of the fuel consumption, coupled with a fall-off in manufacturing costs and other functional criteria, such as enhanced driving and pasive safety of the possible incorporation of additional functions into the components without much effort. But in the past the application of FRP-parts was mostly decorative, e.g. in the case of planked steel metal bodies. Because of the continuous advancement of the fibre-reinforced plastic technology, the development of applications for design work, structural analysis and testing methods the use of FRP in automobiles will increase. Even structural parts like self supporting car side doors will have to contribute to the weight reduction without compromise to the existing requirements. In comparison to the usual passenger car side door made of steel, the self supporting FRP side door offers a lot of advantages: the NVH-behaviour (Noise, Vibration, Harshness), the energy absorption rate, the low specific weight, the possibility of functional integration and the low production costs because of limited series, to mention only a few of them. In this lecture the general requirements for a passenger-car side door made of FRP are presented as well as a description of different conceptions for self supporting FRP doors. On the basis of one conception a static and dynamic simulation has been made. According to this conception the development of a model and the used material model are explained. The results of the structural analysis, which have been investigated by the software ABAQUS and LS-DYNA3D, are presented. The research data resulting from completed testing of components are compared with the calculation results. On the basis of this research a prospect for the application of FRP in the field of side impact protection is given.
