High-pressure container and method of manufacturing high-pressure container
Abstract:
A high-pressure container includes a liner and a fiber layer formed of reinforcing fibers wound around an outer periphery of the liner. The fiber layer has a plurality of hoop layers in which reinforcing fibers are wound in the circumferential direction of the liner to reinforce the body portion. The reinforcing fibers used for a first hoop layer from an inner peripheral side of the fiber layer or the first hoop layer and one or more hoop layers subsequent to the first hoop layer, among the plurality of hoop layers, have a structure in which a plurality of filaments are twisted so as to be inclined with respect to a fiber bundle direction, and have a property of more easily elongating than the reinforcing fibers used for the hoop layer that is located on an outer peripheral side of the fiber layer.
