Abstract: A method of manufacturing a reinforcement layer comprises a preparatory step of preparing to-be-wound fiber, and a formation step of forming an uncured sheet layer including multiple layers of the to-be-wound fiber stacked on an outer circumferential surface. In the formation step, the to-be-wound fiber is wound on the outer circumferential surface in such a manner that, regarding an outer layer of the uncured sheet layer and an inner layer of the uncured sheet layer closer to the outer circumferential surface than the outer layer and adjacent to the outer layer in a stacking direction of the to-be-wound fiber, two end portions of the outer layer are located between two end portions of the inner layer in an axis direction extending along a center axis of a winding target member.

Abstract: A pressure vessel includes a vessel main body, a first protective member, and a second protective member. The vessel main body is configured to contain gas inside. The second protective member is configured to exhibit performance that is different from that of the first protective member. One of the first protective member and the second protective member has recesses that the other one of the first protective member and the second protective member does not have at an end on a peak of a domical panel side provided with the one of the first protective member and the second protective member.

Abstract: A high-pressure tank which is capable of improving the strength of a connecting part between a cylindrical part and a dome part is provided. A high-pressure tank 10 according to the present invention comprises: a liner 20 having a cylindrically-shaped cylindrical part 20a and hemispherically-shaped dome parts 20b which are continuous with both ends of the cylindrical part 20a; and a reinforcing layer 30 including a fiber bundle which is hoop-wound around the cylindrical part 20a of the liner 20 and a fiber bundle which is helically wound around the dome parts 20b thereof. An outer diameter of the end of the cylindrical part 20a is smaller than an outer diameter of a portion of the cylindrical part 20a which excludes the end.
