Abstract The composite material laying parameters are important factors affecting the carrying capacity and quality of the type Ⅳ hydrogen storage vessel. In this article, the composite laying scheme is designed and analyzed by the finite element method. Through 100 groups of laying schemes, the influence laws of circumferential winding layers, spiral winding layers, spiral winding angle, and laying sequence are summarized. The results show that, when the number of spiral winding layers and the number of circumferential winding layers exceed 35 and 25 respectively, the bearing capacity of the hydrogen storage vessel cannot be significantly improved with the increase of the layer number. With the increase in the spiral winding angles, the maximum S11 decreases first and then increases, while the maximum S22 stabilizes first and then increases. But, for different numbers of spiral layers, the turning point of stress rise is different, and the best winding angle is between 55° and 65°. It is found that performing circumferential winding first and then spiral winding is the best winding sequence.
