Carbon Tub

The latest vehicles’ monocoques developed by our team were produced by assembling multiple carbon fibre bulkheads to the bottom of the vehicle’s bodywork with structural adhesive. However, for our newest prototype, we decided to venture out into the creation of a carbon tub (or a carbon monocoque).

This structural component is separated from the aerodynamic bodywork, the last being assembled (and not glued) to the bottom and top of this structure. Therefore, in the future, each of these components can be optimized and updated without compromising each other.

Another advantage of the carbon tub is the greater rigidity, which combined with an optimization of the thickness of the core between the carbon layers, will allow us to minimize the weight of the vehicle to record values, without compromising its rigidity or safety. Regarding the rollbar, we were able to optimize the dimension and position of the steel tubes, in order to have the best of the three worlds: high safety and rigidity, regulation-compliant system and minimum possible weight.
