摘要： A high-pressure tank includes: a liner including a body portion having a tubular shape and side end portions each having a dome shape, the side end portions being provided on opposite sides of the body portion; and a reinforcement layer made of fiber reinforced resin covering an outer surface of the liner. The reinforcement layer includes a tubular member covering the body portion and dome members joined to opposite sides of the tubular member so as to cover the side end portions. The liner includes a first resin layer defining a storage space for storing gas and a second resin layer provided between the first resin layer and at least the tubular member. An elastic modulus of a second resin constituting the second resin layer is lower than an elastic modulus of a first resin constituting the first resin layer.

摘要： A method for manufacturing a high-pressure tank including a liner that stores gas and a reinforcing layer made of a fiber-reinforced resin and covering an outer surface of the liner includes: a first step of forming a cylinder member made of the fiber-reinforced resin; a second step of forming two dome members made of the fiber-reinforced resin; and a third step of forming a reinforcing body that is the reinforcing layer by joining both end portions of the cylinder member and end portions of the two dome members, respectively. The first step includes forming the cylinder member by winding a release material around a mandrel and winding the fiber-reinforced resin on the release material.

摘要： A high-pressure tank includes: a liner having a hollow liner body, a metal cap, a sealing member, and a reinforcing portion. The hollow liner body has an opening in an end portion in an axial direction, and a tubular insert ring harder than the liner body and integrated with the liner body to surround the opening. The metal cap is inserted into the opening. The sealing member seals between the insert ring and the metal cap. The reinforcing portion covers an outer side of the liner, and the insert ring extends to a front side in the axial direction with respect to the liner body and is mounted on the metal cap.
