This chapter explores the optimization of type 4 pressure vessels used for hydrogen storage, focusing on carbon fiber-reinforced composites produced through filament winding. Many studies delve into the intricacies of the winding process to enhance the structural integrity of the vessels. Progressive failure analysis is employed to identify potential weak points and failure modes, guiding the development of optimal designs for improved safety and performance. Additionally, the chapter highlights the importance of considering recycling strategies in the design phase to address environmental concerns associated with composite materials. The findings contribute to advancing sustainable practices in the production and life cycle management of hydrogen pressure vessels.
