Optimisation of 700 bar type IV hydrogen pressure vessel considering composite damage and dome multi-sequencing

•Optimization of the composite stacking sequence of hydrogen tank is performed.•Optimization methods includes multi-sequence dome lay-up characteristics.•Composite damage is taken into account.

This study investigated with the optimisation of the composite stacking sequence of hydrogen pressure vessels manufactured by filament winding. It is a response to the need to develop cost-effective hydrogen energy carriers to permit greater use of hydrogen technology for transport and thus satisfy current environmental requirements. Within the framework of the OSIRHYS IV project, a comparison of the optimal solutions is presented. This comparison focuses on different optimisation strategies and methods including multi-sequence dome lay-up characteristics and composite damage. Optimisation results are compared and discussed with the aim of identifying optimal design rules to meet industrial needs. Finally, prospective work is presented.
