Problems solved by technology

[0007] However, if the amount of carbon fiber composite material used to form the carbon fiber layer of the pressure vessel is reduced (for example, if the thickness of the carbon fiber layer is reduced), there is difficulty in securing sufficient structural rigidity (in particular, resistance to The structural rigidity of the hoop stress applied to the cylindrical part of the pressure vessel in the direction) and the deterioration of stability and reliability
[0008] Therefore, recently, various studies have been conducted to ensure structural rigidity and minimize the use of carbon fiber composite materials, but the results of the studies are still insufficient

Embodiment approach

[0162] In the exemplary embodiments of the present disclosure described and illustrated above, an example has been described in which the pressure vessel includes a single carbon fiber layer including a first annular layer, a second annular layer, and a helical layer. However, according to another exemplary embodiment of the present disclosure, the pressure vessel may include a plurality of carbon fiber layers.

[0163] For example, refer to Figure 13 , the pressure vessel 10 includes an inner liner 100 and a carbon fiber layer 200, the inner liner includes a cylindrical portion 110 and a dome-shaped side portion 120, the side portions are provided at both ends of the cylindrical portion 110, and the carbon fiber layer includes: a first annular The layer 300 is arranged to surround a part of the outer peripheral surface of the cylindrical portion 110; the second annular layer 400 is arranged to surround the other portion of the outer peripheral surface of the cylindrical port...
