An improved molded, reinforced pressure vessel having a winding foot on the liner tank which includes a head, disposed away from the tank and a narrowed neck extending between the head and the tank wherein outer radial dimensions of the head are greater than outer radial dimension of the neck. The improved foot design allows windings to cover more of the liner tank that maximizes the reinforcement provided by the winding and in blow molded liner tanks, the narrow neck restricts the migration of material out of and away from the foot, thus producing a stronger liner tank.

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.

There is avoided a phenomenon where owing to an influence of a stepped portion of the surface of a helical layer positioned in an inner layer of an FRP layer, a fatigue strength of a layer (especially, a hoop layer) adjacent to the outside of the helical layer lowers. To realize this, there is disclosed a tank comprising a liner, and an FRP layer constituted of hoop layers and helical layers alternately formed by winding fiber bundles around the outer periphery of the liner, and in at least one of a plurality of helical layers positioned in an inner layer of the FRP layer, a sectional area of the fiber bundle constituting the helical layer is set to be smaller than that of the fiber bundle constituting another layer formed outside the helical layer. When the helical layer is formed by using this fiber bundle having the small sectional area, unevenness in the helical layer becomes small, and the unevenness can be prevented from being transferred to the other layer (e.g.,the hoop layer) formed outside the helical layer.

Composite pressurizable structures overwound with fibers or braided bundles of fibers are described. The pressurizable structures comprise one or more axial sections which themselves comprise both concave and convex surfaces. The shape characteristics are related to geodesic as well as to non-geodesic trajectories of the fibers. Axial sections of the pressurizable structures can be rotated, expanded, or bended with respect to their longitudinal axis. Such pressurizable structures may be used in pressure vessels, flexible pipelines, spring elements, robotic actuators, adaptive buildings among other uses. Manufacturing techniques facilitated by the present structures allow for the construction of very large structures.

A pressure vessel includes a vessel body and a fiber reinforced plastic layer formed on the surface of the vessel body, wherein the fiber reinforced plastic layer include fiber reinforced plastic in which reinforcing fibers are impregnated with plastic, a strand elastic modulus of the reinforcing fiber is 305 GPa or higher, and a tensile elongation of the reinforcing fiber is 1.45 to 1.70%. A carbon fiber for a pressure vessel has a strand elastic modulus of 305 GPa or higher and a tensile elongation of 1.45 to 1.70%.
摘要:
A pressure vessel arranging and integrating a plurality of vessel structures each including a cylindrical liner opened at both ends and a fiber reinforced resin layer covering the outer periphery of the peripheral wall of the liner. Dome-shaped communicating members bulging outward are fixed across both respective ends of the liners of the vessel structures, thereby making the interiors of these liners communicate with each other and closing the open ends of these liners. This pressure vessel can be installed with no wasted space, and also allows an increase in capacity.

A pressurized container includes two plastic casings (12, 14) and produces a leakproof container or storage arrangement which is economical to produce. A gap opening (24) between the casings (12, 14) extends up to a point at which the casings (12, 14) are positioned together in a coaxial manner. An external support ring (22) with a wedge-shaped tapering (26) extends to that point and is embodied as an individual piece or has at least two metal, ring-shaped individual segments (28, 30).

A pressure vessel for propellants, an explosion preventing method of the same, and a manufacturing method of the same are disclosed. The pressure vessel for propellants comprises a body provided with a cylindrical portion between a forward dome and an aft dome, and has an inner space where propellants are arranged. The pressure vessel also includes an insulation layer disposed on an inner wall of the body and configured to insulate the body from the inner space when the propellants are ignited; and a nozzle mounted at the aft dome and through which combustion material from the propellants is exhausted out. The body comprises a first hybrid fiber layer which forms the cylindrical portion, the forward dome, and the aft dome, and has a mechanical property lowered at a temperature more than a specific temperature such that the forward dome and the aft dome collapse by an inner pressure when the propellants are abnormally combusted. The body further comprises a second hybrid fiber layer which forms at least a part of the cylindrical portion, and maintains its mechanical property when the propellants are abnormally combusted.

摘要:
A flexible pressure vessel is constructed from at least one pair of upper and mating lower dome shaped cell portions. The dome portions are molded from sheets of resilient material and joined together by radio frequency welding or high-strength adhesives. Upper and lower passageway portions extend outwardly from each cell portion to the surrounding sheet material. When the cell portions are joined the passageway portions are joined to form a passageway for connection to a valve or another cell. Upper and lower rings surround the upper and lower cell portions to provide reinforcement for the cells. First and second blankets of heavy-duty fiber reinforced material are attached over the upper and lower cell portions and stitched in place with heavy-duty stitching extending through the resilient material surrounding the cell portions. Cell shaped sponges impregnated with absorbent materials are encased in liquid and gas impermeable plastic tubing and inserted into the cells prior to joining of the cell portions. Heat-reflecting plastic film or metal foil is inserted between blankets and the cell portions. The heavy duty stitching is high-pressure loop and lock braiding. The passageway has a cross-section of between 0.050 and 0.100 inches. An apparatus and method are described for constructing the flexible pressure vessel.
