Abstract: A pressurized-gas storage vessel includes a liner defining a chamber therein, the chamber being configured to receive a gas; a first wrapping surrounding the liner; and a second wrapping surrounding the liner. Methods of manufacturing and using the storage vessel are also disclosed.

Abstract: The present disclosure provides mounting plates having a mounting portion adjacent to a plurality of fastening regions and a flexing portion adjacent to a mounting feature. The fastening regions can be connected to a frame system. The mounting feature can be connected to an end of a pressurized tank. The end of the pressurized tank can move relative to the frame system and the mounting plate can flex such that the flexing portion moves out of the plane of the fastening region to accommodate the motion of the end of the pressurized tank. Connection to the end of the pressurized tank can be provided at a tank collar than can be bonded or threadably connected to the mounting plate via a connection mechanism. The connection mechanism can be an expandable plug or a sleeve that connects to the tank collar.

Abstract: A device, system and method to support the ends of composite pressurized storage vessel, including supporting two ends of a cylindrical composite pressurized storage vessel with an axial rod/tube fixed axially inside the storage vessel fixed at each end; and providing a fluid pathway into the vessel from at least one of the two ends which is not obstructed by the axial rod/tubing.

Abstract: A cooperating rack structure comprising at least two modules affixed to legs and a method of reduced weight vertical storage of fuel tanks for use in motor vehicles wherein the fuel tanks form a cooperating portion of the rack superstructure.

Abstract: A localized fire protection system for composite overwrapped pressure vessels which uses net or mesh which stretches in at least one direction. They can be elastomeric or polymeric or any material and/or weave that provides said function. Wrapping sections held together via a flammable fuse connected to a relief valve under pressure from the net wrappings to block a relief valve pathway to replace stored gas in case of a localized fire.

Abstract: A device, a system, and methods for tracking conductive composite pressurized gaseous storage tanks. The system including anchoring an RFID device in a non-conductive blind boss, wherein the anchor material has a low dielectric and has minimal reflection of RF energy.

Abstract: Devices and methods for addressing permeation of a gas through a liner of a pressure vessel involve a porous layer between the liner and a composite shell of the pressure vessel around the liner. The porous layer provides fluid communication with atmosphere for gases that permeate through the liner. Such porous layers may be provided in a continuous wound set of fibers about the liner. Further, an inner composite structure may be provided between the liner and the porous layer to reduce the rate of permeation to the porous layer.

Abstract: A composite fuel tank, formed by winding filaments or strips around a plastic liner and binding the material with a curable binder. Embedded within the wrapped material at predetermined depths from the surface which provides a color indication of the level of damage due to tears, gashes, cuts and the like. The color indicator is part of a visual inspection method to determine tank damage and the extent of repair necessary.

Abstract: A fuel holding device is secured to a vehicle by means of straps and brackets, which sits on a system of gaskets to prevent longitudinal sliding and rotation. A gasket system for preventing longitudinal sliding is disposed circumferentially around the tank body, and between the tank body and a circumferential bracket system that includes a U-shaped strap and an L-shaped bracket. The gasket system comprises a wedge-shaped base and a slider portion, with the U-shaped strap secured around the slider portion. A system for preventing rotation of a fuel-holding device has a circumferential wedge gasket segment, or a corrugated segment, positioned at a gap between the U-shaped strap and the L-shaped bracket.
