A method for manufacturing a high-pressure tank including a liner and a fiber-reinforced resin layer, the fiber-reinforced resin layer having a first reinforcing layer covering an outer surface of the liner and a second reinforcing layer covering an outer surface of the first reinforcing layer includes: forming a cylinder member made of a fiber-reinforced resin and having fibers oriented in a circumferential direction of the cylinder member; forming two dome members made of the fiber-reinforced resin; forming a reinforcing body that is the first reinforcing layer by joining the cylinder member and the dome members; and forming on an outer surface of the reinforcing body the second reinforcing layer made of the fiber-reinforced resin and having fibers oriented across the dome members.

A high-pressure tank includes: a cylindrical hollow container; an outer shell that is formed of a fiber-reinforced plastic band which is wound on an outer circumference of the hollow container to cover the outer circumference; and a cap that is attached to an inner side of at least one of one axial end and the other axial end of the outer shell. The hollow container is formed of a material which has airtightness and which is able to expand and contract in an axial direction and a radial direction inside the outer shell, and a frictional portion that is used to set a frictional resistance to an inner circumferential surface of the outer shell to be greater than that in the other area is provided in an axial intermediate portion on an outer circumferential surface of the hollow container.

The disclosure provides a module including a first member that is a battery or a gas tank in which pressure fluctuation happens along one axis direction, a pair of second members, the second members being arranged on end portions of the first member in the one axis direction, respectively, and a binding member binding the first member and the second members while pressurizing them. The binding member is formed as fiber-reinforced plastic (FRP) containing fiber and resin is revolved. The FRP includes a base fiber layer with a fiber direction along a revolution direction, and a reinforcing fiber layer with a fiber direction different from that of the base fiber layer. The reinforcing fiber layer has a non-overlapping portion between both end portions in a revolved state. The non-overlapping portion is positioned in a region facing the first member.

Cladding of the interior of a component part of a pressure vessel is shown. A lining which conforms to at least a portion of the interior geometry of the component is positioned in the interior of the component. The lining is then pressed into the component past its yield strength. The lining is then fused to the component.

A pressure vessel is disclosed comprising an inner vessel with a rotationally symmetrical middle part with an axis of symmetry along the middle part and two dome-shaped polar caps which close off the middle part, and an outer layer, wound on the inner vessel to reinforce it, made of fiber composite material made of a plurality of plies of fibers embedded in a matrix material which are arranged one above another, which run as a fiber band made of a number of fibers with a location-dependent and position-dependent fiber orientation across the inner vessel, wherein the fiber band at least in some of the plies enters from the middle part at a respective entry fiber angle relative to the axis of symmetry into the region of the dome-shaped polar caps.

A container assembly, in particular of an air pressure system of a utility vehicle, includes a first region and a second region, wherein the first and the second region together enclose at least part of a container interior, wherein the first and the second region are connected to each other via a joining region, and wherein the joining region is subjected to a shearing load in the event of loading from the container interior side.

An accumulator vessel (10) includes a screwable portion (3) and a lid portion (2) that is positioned at an axially inner side of the screwable portion and an axially inner surface configures a pressure bearing plane. The lid portion includes a protruding portion (22) extending axially outward on an inner circumferential side, and the protruding portion configured to abut against an axially inner end side of the screwable portion to separate an axially inner surface of the screwable portion on an outer circumferential side thereof apart from an axially outer surface of the lid portion on an outer circumferential side thereof.

Disclosed is a gas storage, preferably of hydrogen, and is in the form of a multi-capillary structure. The multi-capillary structure has a constant section over a certain length, which section then reduces sharply, down to a value at which the multi-capillaries become sufficiently flexible. The area of flexibility of the multi-capillaries has a length sufficient for the transportation of hydrogen to a fuel element. In this way, a flexible multi-capillary gas pipeline is created, which pipeline is integrated with a volume of stored hydrogen, the function of which pipeline is to supply hydrogen to the fuel element. The technical result consists of the provision of rapid priming of a micro-capillary vessel with high pressure gas and the regulated release of the gas from the vessel into a collector, where a moderate pressure (<1 MPa), required for operation of the fuel element, is maintained.
