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
