The fiber-reinforced resin layer includes an inside layer formed on the tank liner side, and an outside layer formed on an outer periphery of the inside layer. The inside layer is formed as a dense layer, while the outside layer is formed as a layer that is less dense than the inside layer by forming a larger number of airspaces in the outside layer than there are in the inside layer.

  • Patent number: 8464893
    Abstract: A pressure container has an inner shell with a pair of fittings and a reinforcement layer formed around the inner shell, and is configured so that a reinforcement member is attachable to the pair of fittings in a process of forming the reinforcement layer and a functional component which performs a predetermined function is also attachable to the fittings. This can allow the reinforcement member to prevent expanding deformation of the pressure container in production of the pressure container, and can ensure effective use of openings after removal of the reinforcement member.
