Problems solved by technology

However, it is very complicated to apply the spray at a uniform application rate
In addition, when the exterior surface is subjected to shocks, the applied refractory material may be lost, thereby losing fire resistance
[0010] That is, the time and cost required for the process of manufacturing high-pressure containers according to the respective sequential processes are undesirably high, and, although the manufacturing process and time are long, it is difficult to obtain uniform quality

Abstract

Proposed are a high-pressure vessel and a manufacturing method thereof, the high-pressure vessel comprising: a liner including a cylinder portion and dome portions disposed at both ends of the cylinder portion, and storing a high-pressure fluid therein, each of the dome portions having a dome shape; a composite material layer surrounding an outer surface of the liner; and a protective layer surrounding an outer surface of the composite material layer and including a shock-absorbing layer, a heat-resistant layer, and a surface protective layer, which are sequentially laminated, wherein the shock-absorbing layer of the protective layer is made of a resin material and formed by an injection method on an inner surface of the heat-resistant layer.

Description

technical field [0001] The invention relates to a high-pressure container and a manufacturing method thereof. More particularly, the present invention relates to a high-pressure container capable of safely storing high-pressure gas, such as a fuel tank of a natural gas vehicle or a hydrogen tank of a fuel cell vehicle, and a method of manufacturing the same. Background technique [0002] A natural gas (CNG) vehicle or a hydrogen fuel cell vehicle is equipped with a high pressure vessel to compress the gaseous fuel under high pressure to store the gaseous fuel. [0003] Generally, high-pressure vessels are manufactured through the following manufacturing process: the inner liner is made of synthetic resin to reduce weight; a composite material such as carbon fiber is wound on the inner liner; protective pads are attached to the composite material again to absorb shock on the outer surface, This prevents damage to the inner liner; and the fiberglass is rewound on the pad to p...
