In this study, we have proposed a new method to manufacture high pressure composite vessels for hydrogen storage. With the new method, a new filament winding machine which has multiple delivery eyes is used. By laminating composite layers with a lot of delivery eyes at once, the manufacturing time decreases significantly. To eliminate the trouble of tying ends of a lot of fiber bundles which has been a problem in this method, we have added layers for continuous changing the lamination angle in a winding pattern. To evaluate the effect of above layers on the strength of the vessel, we manufactured prototype composite vessels using the above mentioned method with different conditions, and compared with conventional vessels. By adding layers for changing the lamination angle, it became possible to laminate all layers of a vessel continuously. Furthermore, by changing the lamination angle to decrease the gaps between fiber bundles in the layers, the experimental-by-ideal strength ratio improved 21%, and the material usage efficiency improved 29%.
