2023 JEC Composites Innovation Awards Winner- Dr Ing. h.c.F Porsche AG and partner Action Composites

World’s first carbon roll cage for production cars made by Dr. Ing. h.c. F. Porsche AG (Germany) and partners: Action Composites GmbH– Kube GmbH Ingenieurbüro– Lab for Lightweight Design, IKTD, University of Stuttgart

Extreme lightweight carbon roll cage, to be road legally fitted into a production car, enabled by engineering a unique geometry.
The initial metal design withstands extreme elongations. Thus, the use of carbon fibers, presented a major challenge for this application due to the low elongations at break. The Engineering innovation of the project is a new 3 step structural optimization process providing a specific design suitable for CFRP under full consideration of an extremely limited design space as well as multiple crash and FIA load cases (…).

Key benefits
High weight reduction compared to steel and even titanium
Topology optimized, unique bionic design
Innovative calculation approach – automated link between CAD an FE
Innovative manufacturing process – structural hollow part in serial production
Fulfills FIA load collective
