Abstract: A storage module including a tank includes: a filling port configured to fill the tank with gas, a supply port configured to supply gas from the tank to a supply destination a release port configured to release gas from the tank, a first channel that is a channel connecting the tank and the filling port, a second channel that is a channel connecting the tank and the supply port, and a release channel that is a channel connecting at least one of the first channel, the second channel, and the tank, to the release port.

Abstract: A tank includes a liner that includes a barrel portion in a cylindrical shape and a pair of dome portions provided at both ends of the barrel portion in the axial direction, and a reinforcing layer that covers the liner and that is formed from a fiber reinforced resin formed by impregnating a fiber bundle with a resin. A portion of the reinforcing layer that covers the dome portions includes a radial arrangement layer in which fibers of the fiber bundle are arranged radially along the radial direction of the dome portions when seen in the direction of an axis of the tank.

Abstract: A high-pressure tank includes a liner that includes a body that is cylindrical in shape and a pair of dome portions each of which is provided at a respective end of the body in an axial direction, and a reinforcing layer provided on an outer circumferential face of the liner. The reinforcing layer includes a pair of resin rings each of which is provided encircling a respective end portion of an outer circumferential face of the body, a hoop layer that covers part of the outer circumferential face of the body, between the resin rings, and a helical layer that covers the resin rings, the hoop layer, and the dome portions. The resin rings are configured to cover part of the body from boundary portions between the body and the dome portions, and increase in thickness from the boundary portions toward a middle of the body.

Abstract: A high-pressure tank includes an assembly of a pipe split body having a pipe liner and a pipe reinforcement layer covering an outer circumferential surface of the pipe liner, first dome split body having a first dome liner and a first dome reinforcement layer covering an outer circumferential surface of the first dome liner, and second dome split body having a second dome liner and a second dome reinforcement layer covering an outer circumferential surface of the second dome liner. The pipe split body and the first dome split body are assembled such that the first dome liner is located in the outer portion of the high-pressure tank relative to the pipe liner. The pipe split body and the second dome split body are assembled such that the second dome liner is located in the outer portion of the high-pressure tank relative to the pipe liner.

Abstract: Provided is a pressure vessel strain analysis device capable of grasping a correlation between manufacturing conditions and strains. The pressure vessel strain analysis device includes an analysis unit. Based on a plurality of manufacturing conditions of a plurality of pressure vessels and a plurality of strains acquired by an image correlation method in a state where a predetermined internal pressure is applied to the plurality of pressure vessels manufactured under the plurality of manufacturing conditions, the analysis unit calculates a correlation between the plurality of manufacturing conditions and the plurality of strains.
