Problems solved by technology

[0003] In a high-pressure vessel with a metal liner, there is a problem of fatigue of the metal liner caused by expansion / contraction of the vessel with gas filling and discharge
On the other hand, if the amount of fiber in the composite housing is reduced for weight reduction and cost reduction, the amount of expansion / contraction will increase, thereby limiting the number of allowable filling / draining

Abstract

A high pressure tank 10 comprises a metal liner 20 having a desired tank shape; and a composite material shell 30 formed on the periphery of the metal liner 20 . The metal liner 20 comprises a cylindrical barrel portion 21 , a mouthpiece 22 located at each of two end portions, and a cap portion 23 connecting barrel portion 21 with mouthpiece 22 . Extensible portions 211 of bellows configuration are formed along the entire length of the metal liner 20 in the axial (lengthwise) direction. The extensible portions 211 impart elastic action through opening and closing (deformation) of their basal portions 211 b, thereby preventing slippage from occurring between the metal barrel portion 21 and the composite material shell 30 when the high pressure tank 10 expands and contracts.

Description

technical field [0001] The invention relates to a high-pressure container made of composite material and a manufacturing method of the high-pressure container. Background technique [0002] As a high-pressure vessel that mainly stores gas, a high-pressure vessel that replaces the existing steel with a composite outer shell covered with a metal inner liner is practically used. [0003] In a high-pressure vessel using a metal liner, there is a problem of fatigue of the metal liner caused by expansion / contraction of the vessel with gas filling and discharge. On the other hand, reducing the amount of fiber in a composite casing for weight reduction and cost reduction will increase the amount of expansion / contraction, thereby limiting the number of allowable filling / draining times. [0004] Therefore, there has been proposed a pressure vessel in which a part of the metal liner has a curved portion that moderates axial fluctuations caused by internal pressure fluctuations (see Pa...
