Abstract:
A motor vehicle outer tank for a cryogenic fuel which is situated in an inner tank which is positioned within the outer tank is, for space and weight-saving purposes, characterized in that it is of flat design, and is designed in particular as a parallelepiped, and in that planar side walls of the outer tank are at least partially of sandwich design or are reinforced with sandwich plates.
Abstract:
A cellular reservoir flexible pressure vessel is formed as a series of closely packed tubes fitted into a pair of opposing end caps. The end caps have individual receptacles sized and shaped to receive the tube ends that are secured with adhesive or radio frequency welding. At least one end cap has a passageway for connection of the vessel. The flexible pressure vessel has a pressure relief device comprising a reduction in thickness of one end cap at a predetermined location. When subjected to overpressure it fails at the predetermined location. Other pressure relief devices include: a projecting member on the vessel surface, a weakened section of the passageway, a weakening or an absence of braiding material or hoop winding at a predetermined location on the vessel surface or along the passageway, a weakening or spreading of fibers in either the reinforcing panels or the flexible blankets covering the vessel.
Abstract:
A reinforced composite structure (29) is disclosed. The structure is formed by opposed layers of material extending over a core and continuous bundles stitched in a repeating pattern through the opposed layers (30, 32) and the intermediate core (28) to form the reinforced composite structural member (29).
Abstract:
A device for the storage of compressed hydrogen gas comprises a plurality of glass capillary tubes each having a sealed extremity and an open extremity, wherein said plurality of glass capillary tubes is sheathed in an external tubular cover, and wherein the open end of a bundle of said tubular covers is housed in an adaptor, and wherein said adaptor is suitable to allow compressed hydrogen gas to be added to, and to prevent said hydrogen gas from escaping from, said glass capillary tubes.
Abstract:
A structural component with at least two side members has a support structure that includes a partition with multiple curved portions forming cells. The partition connects to the side members and extends between the side members at least partially along straight lines. The partition may extend along one or more straight lines from one side member to the other. One structural component is a container with a wall about the internal support structure. The container cells may be formed with a core structure. The core can include a permeable storage material and may be retained after formation, or may be removed. In some cases the container wall has generally planar surfaces, which may include surface undulations. Core structures are also provided for forming structural components. Formation can include casting a material about a core structure within a mold to form a partition extending between two or more sides.
Abstract:
The present invention is directed to a new manufacturing process for a FRP honeycomb structure where the honeycomb core assembly is arranged parallel to the surface. The honeycomb core is made from FRP prepreg with double structural walls and is manufactured by stiffening using heat and pressure. In a honeycomb core assembly set tank, a plurality of internal tanks are gathered in honeycomb core assembly. An internal tank FRP wall maintains the pressure of the internal tank, while an external FRP wall, heat foamed plastic resin and rigid FRP hull of set tank endure the external shock loading. A honeycomb core structure of six-corner cell can be infinitely arranged, and its structural position is unique. A set tank in which a plurality of internal tanks are gathered into a honeycomb core assembly can be arranged in infinite combinations, such that the total capacity can be extremely large.
Abstract:
A cellular reservoir flexible pressure vessel is formed as a series of closely packed tubes fitted into a pair of opposing end caps. The end caps have individual receptacles sized and shaped to receive the tube ends that are secured with adhesive or radio frequency welding. At least one end cap has a passageway for connection of the vessel. The vessel may be formed in a variety of useful shapes and the tubes may have various internal and external cross-sections. The end caps may be filled with sintactic foam with canals leading to the passageway. Microtubes through the syntactic foam may connect the tubes to the passageway. The vessel is further strengthened by overwrapping with high-strength braiding material, hoop winding or by overlayment with high-strength fabric. The vessel is further strengthened by coating with plastic resin. Apparatus and methods for forming the cellular reservoir flexible vessels are described.
Abstract:
