Abstract: A pressure vessel (2) for the storage of fluid has a core (10) made of metal or polymer and is wrapped either completely or partially from outside with a high strength fibers (21, 22) for reinforcement wherein one of the reinforcing fibers is a metal wire (21) of a single filament or cables of multi filaments having strength from 2000 MPa to 6000 MPa. The wire has a plastic ductility of over 20% in reduction in area (RA) at tensile fracture. The metal wire (21) is made of steel or nickel or titanium or their respective alloys. The core (10) of the vessel (2) is first wrapped with a resin covered ceramic fibers such as carbon, fiberglass and subsequently wrapped with the metal wire (21) with or without other fibers (22). The metal wires (21) can be of different diameters in parallel or cabled forms.
Abstract: A light weight pressure vessel (10) has been proposed. The vessel (10) is made of a steel, aluminum or non-metal liner (11) which is reinforced with high strength steel wires (21) of 2000-7000 MPa strength. The matrix is filled with a polymer epoxy resin (45). A top layer of fabric tape (33) soaked in resin (45) has been used to embed the finish end (24) of the wire (21) and to provide a protective layer over the wire reinforced area. The mesh or net fabric wrap tape (33) has periodic openings to allow penetration of polymer epoxy resin (45). A top coat of a UV resistant polyurethane paint (47) has been applied.
