A high-pressure tank configured to store a fluid includes: a liner; and a fiber-reinforced resin layer configured to include a fiber and to cover surface of the liner. The liner includes: a cylindrical liner portion in a cylindrical shape; and dome liner portions in a dome shape connected with respective sides of the cylindrical liner portion, each dome liner portion being connected with the cylindrical liner portion, such that an outer surface of the dome liner portion is inclined at a predetermined angle to an outer surface of the cylindrical liner portion. The fiber-reinforced, resin layer includes a hoop layer formed on the outer surface of the cylindrical liner portion to cover the outer surface of the cylindrical liner portion and provided by hoop winding that winds the fiber substantially perpendicularly to a central axis of the cylindrical liner portion. The hoop layer is formed, such that an outer surface of the hoop layer has a smaller angle than the predetermined angle to the outer surface of the dome liner portion at a boundary between the hoop layer and the dome liner portion.

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.

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.

An impact and fire resistant coating laminate is provided which serves as an outer protective coating for a pressure vessel such as a composite overwrapped vessel with a metal lining. The laminate comprises a plurality of fibers (e.g., jute twine or other, stronger fibers) which are wound around the pressure vessel and an epoxy matrix resin for the fibers. The epoxy matrix resin including a plurality of microspheres containing a temperature responsive phase change material which changes phase in response to exposure thereof to a predetermined temperature increase so as to afford increased insulation and heat absorption.

The invention relates to a fibre-reinforced pressure vessel (1, 6) comprising a rigid gas- or fluid-tight body (2, 7, 13, 19) overwound with fibre filaments (3, 10, 11, 18), whereby the fibre filaments are wound such that at least a number of fibre filaments can freely move in respect of one another and when the pressure vessel is under internal pressure the fibre filaments are strained exactly in their longitudinal direction. The invention also relates to a method of manufacturing a fibre-reinforced pressure vessel whereby no matrix material (for example, resin) is used so that at least a number of fibre filaments would be incorporated in a matrix for that section of the pressure vessel in which the fibre filaments can freely move in respect of one another.
摘要:
An innovative technology for composite overwrapped pressure vessels (COPVs) has been developed which significantly increases cost effectiveness, increases reliability, and reduces weight over state-of-the-art COPVs. This technology combines an innovative thin liner made of a metal having a high modulus of elasticity and a high ductility, a high-performance composite overwrap and a high-performance film adhesive at the overwrap/liner interface. The metal liner can be fabricated from readily available titanium alloy sheet and plate using a combination of spin forming and machining to fabricate components and electron-beam welding for tank assembly. The composite overwrap is filament-wound onto an adhesive-covered titanium liner and the overwrap and adhesive are co-cured in an oven to yield an integrated tank structure.

Glass fiber reinforced plastic container for liquefied petroleum gas or compressed air. The container is made of two halves, the open ends of which are conically chamfered and joined to each other by an adhesive. In each half the reinforcement is made with inner, intermediate and outer layers, which comprise longitudinally as well as transversely and diagonally oriented bundles of reinforcing strands.

A pressure vessel includes a liner having an end wall assembly formed by connecting two rigid end wall members at a fixed distance from each other by a connecting member, and an elastic peripheral wall sheet fixed to the two end wall members so as to enclose a space between them. The two end wall members are made of aluminum alloy by an extrusion process. The connecting member is a pipe made of aluminum alloy by an extrusion process and having a large number of communicating holes in the pipe wall. The peripheral wall sheet is made of aluminum foil and is formed in a cylindrical shape so as to enclose the space between the two end wall members. Around the liner are provided a helical reinforcing layer and a hooped reinforcing layer which are both made of FRP. This pressure vessel is lightweight and can be easily produced at a low cost.
