【 摘 要 】

This article deals with the design of CFRP composite monocoque chassis for Formula Student race car. The design objective is to maximize a specific torsional stiffness of the monocoque and also satisfy the safety requirement assigned by Formula SAE. The sandwich structure has been used regarding to its high flexural rigidity per weight. The thickness and stacking sequences of composite plies have been optimized for each particular zone of the monocoque chassis using the FEM simulation.
