Reducing the weight of pressure vessels is a key objective in different sectors like automotive or aerospace. This can be achieved by replacing Type III and IV pressure vessels through Type V design. Nonetheless, Type V pressure vessels still use metallic bosses as an interface to surrounding structures. These metallic bosses lower the performance of the Type V design due to its mass and mechanical and thermal properties. This study investigates the feasibility of CFRP bosses using different stiffness distributions by means of finite element analysis. Different materials are investigated to demonstrate the potential of these structures. The weight benefit as well as the mechanical performance is compared to metallic bosses.     «
