Lightweight body design using fibre-reinforced plastics (FRP) is appropriate in care 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 passive safety or the possible integration 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. Based on the continuus progress 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 could 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 many advantages: the better NVH-behaviour, the high energy absorption rate, the low specific weight, the possibility of functional integration and low production costs in low volume production, 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 conc epts for self supporting monocoque FRP doors. On the basis of one concept a static and dynamic analysis has been made. According to this concept the development the development of the material model used is explained coupled with other results concerning modelling FRP for crashworthyness analysis. 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.
