During braiding, carbon fibres are deposited onto a mandrel while adapting its shape. State-of-the-art braiding technology is limited to convex mandrels but an adapted concept is being investigated for complex parts with concave cross-sections. In cooperation with Roding Automobile GmbH, the SGL Institute for Carbon Composites (LCC) of the Technical University of Munich demonstrated the braidability of a windscreen frame with concave sections. By Dipl.-Ing. Andreas Kollmannsberger, research associate, Dipl.-Ing. Michael Brand, research associate Prof. Dr.-Ing. Klaus Drechsler, head of the SGL Institute for Carbon Composites, Technical University of Munich T he Roding roadster is a two-seat mid-engine sports car with a carbon fibre chassis and a powerful engine. Maximum performance and driving dynamics are achieved through consistent lightweight construction. The roadster will be produced in small series with fifty units planned per year. The main chassis cell is made of carbon fibre reinforced plastic, as are exterior parts (Fig. 1).
