摘要
The present invention provides a pressure shell formed by winding reinforcement fibers with resin material for hardening on an outer surface of a hollow tank base body, a high-pressure tank having the pressure shell, a manufacturing method of the high-pressure tank, and an apparatus for manufacturing the high-pressure tank. The pressure shell adopts the laminated structure in which a large number of fiber layers each formed by winding the reinforcement fibers around the tank base body are laminated. In a state the inside of the high-pressure tank is emptied, a compressive stress is applied to a lower fiber layer and a tensile stress is applied to an upper fiber layer. Particularly, in winding the reinforcement fibers around the tank base body, the reinforcement fibers are wound while filling fluid for pressure regulation in the tank base body, regulating a pressure applied to the fluid for pressure regulation, and adjusting a tension applied to the reinforcement fibers.
