Abstract: A manufacturing method and a jig for a high-pressure tank includes a filament winding step in which a reinforcing shaft is inserted from a cap toward the other end of a liner, the axial length of the liner is fixed by the reinforcing shaft, and a fiber-reinforced resin is wound; and a thermal curing step in which the fixing of the reinforcing shaft to the other end of the liner is released so that the liner can change in the axial direction, and the fiber-reinforced resin is heated.

Abstract: An apparatus for manufacturing a surface-layered part comprises: a main support that supports a surface layer member to be placed under a base member; a pulling device arranged at a periphery of the main support, wherein the pulling device includes a pulling member that pulls an edge of the surface layer member, which is in a position away from the edge of the base member, outward with respect to the base member; a base member clamping device that fixedly clamps the surface layer member, having been pulled outward by the pulling member of the pulling device, against the main support via the base member placed over the surface layer member; and a relieving device that separates the pulling member from the edge of the surface layer member, which has been moved outward with respect to the base member by the pulling device, to allow the edge of the surface layer member to wrap around the edge of the base member by an elastic restoring force of the surface layer member, thereby integrating them; and a control device that drives and controls the base member clamping device, the pulling device, and the relieving device.

Abstract: In a method for manufacturing a high-pressure tank, a fiber bundle impregnated with a thermosetting resin base material is wound around an outer surface of a liner in a state where tension is applied to the fiber bundle in a filament winding step. The filament winding step includes a pressure-bonding step and a cutting step. In the pressure-bonding step, a terminal end portion which is a winding end of the fiber bundle is thermocompression-bonded to an outer peripheral portion of the fiber bundle wound around the liner. In the cutting step, a surplus portion of the fiber bundle is cut by a cutting tool.

Abstract: A molding jig for molding a laminate, which includes reinforced fiber sheets laminated on each other, extends in the length direction, and has a cross-sectional shape having a curved portion in a cross section obtained by cutting the laminate on a plane orthogonal to the length direction, into a three-dimensional shape having a bent portion in the length direction. The molding jig includes a female die for forming the bent portion, a male die for engaging with the female die with the laminate therebetween for forming the bent portion, and a stretchable supporting member between the female die and the laminate. The laminate comes in contact with the male die on both length-direction sides of the molded bent portion, and the supporting member is over a region including the female-side molding surface.

Abstract: A polar end ring mechanism for use with composite pressure vessels. The end ring is designed to support a pressure vessel during its formation via filament winding. The end ring helps define an opening at one of the polar ends of a tank. Spikes positioned along a portion of the end ring help prevent rotation or translation of the tank during formation and provide an improved mechanical lock with the tank body. A cap may then be secured to the polar end ring after formation in order to close the pressure vessel.

Abstract: In a filament winding apparatus, a supplying device supplies fiber bundles to a surface of a core material. A moving part is movable relative to the core material, and rotatable around a rotational axis extending in a vertical direction. A small diameter aligning guide part is placed at the moving part and has an opening portion through which the core material can pass. The small diameter aligning guide part guides fiber bundles to an outer peripheral surface of the core material such that the fiber bundles are arranged side by side in a circumferential direction of the core material. The tightening fiber bobbin supporting part is placed at the moving part and rotates around a center of the opening portion. A winding guide rotates with the tightening fiber bobbin supporting part and guides a tightening fiber bundle drawn from a tightening fiber bobbin toward the surface of the core material.

Abstract: A method of sealing a wiring-harness includes the steps of: a) dispensing a length of a sealing-tape onto a platform, the sealing-tape having a first-surface and a second-surface opposite the first-surface. b) separating a plurality of wire-cables from a portion of the wiring-harness. c) applying the plurality of wire-cables to a first-half of the first-surface of the sealing-tape. d) folding a second-half of the sealing-tape over the separated plurality of wire-cables such that the second-half overlays the first-half. e) pressing the second-half of the sealing-tape such that the second-half contacts the first-half between the separated plurality of wire-cables, thereby forming a cable-band. f) coiling the cable-band into a generally cylindrical-shaped seal. g) compressing the cylindrical-shaped seal isostatically such that interstitial-voids within the cylindrical-shaped seal are reduced in size.
An apparatus for sealing a wiring-harness is also provided.

Abstract: A filament winding device includes: a helical winder which winds a fiber bundle around a liner; a bobbin supporting shaft which rotatably supports a bobbin for providing the fiber bundle to the helical winder and a bobbin different from the bobbin in a state in which winding-initiation ends of the fiber bundle wound around the bobbin and winding-termination ends of the fiber bundle wound around the bobbin connect to each other; and a fiber bundle storage unit. The fiber bundle storage unit has a stopper which can switch the fiber bundle storage unit between a storage state in which the fiber bundle is stored in the fiber bundle storage unit and a storage-released state in which the fiber bundle has been released from storage in the fiber bundle storage unit and the fiber bundle is supplied from the fiber bundle storage unit to the helical winding unit.
