    Abstract: The present invention provides a method for manufacturing a high pressure tank having a reinforcing layer on an outer surface of a liner provided with dome portions at both end portions of a round tubular shaped body portion, the method including: a winding process of winding a fiber bundle containing a curable resin and having a predetermined tension on the outer surface of the liner; and a reinforcing layer forming process of forming the reinforcing layer by curing the curable resin contained in the fiber bundle wound around the outer surface, in which the winding process is performed so that the tensions of the fiber bundles at the both end portions are lower than a tension of the fiber bundle at a general portion of the body portion defined between the both end portions.

    Abstract: A method for manufacturing a liner includes a shaft preparation step. In the shaft preparation step, a shaft assembly is prepared in which an annular shaped first attachment and an annular shaped second attachment are attached to the outer circumferential portion of a tubular shaped shaft including an air supply hole. The method for manufacturing the liner further includes a parison supply step of arranging the shaft assembly on an inner side of a parison, and a blow molding step of closing a mold device, supplying air into the parison from the air supply hole to thereby cause the parison to expand, and obtaining a liner molded body. The method for manufacturing the liner further includes a detachment step of removing the shaft from the first attachment and the second attachment, and taking out the shaft to the exterior of the liner molded body.

    Abstract: Provided is a high-pressure tank in which rupture strength of a reinforcement layer can be improved more surely than in a conventional technique. The high-pressure tank includes a liner having a hollow interior and a reinforcement layer formed on an outer surface of the liner. The reinforcement layer includes unit layers stacked on the outer surface of the liner. A unit layer includes a band-shaped fiber bundle (band B) which includes a curable resin and is wound around the liner such that the band-shaped fiber bundle (band B) is disposed in line along a width of the unit layer. The band-shaped fiber bundle (band B) widens as the unit layers are stacked from an inner peripheral portion of the reinforcement layer to an outer peripheral portion of the reinforcement layer.

    Abstract: A filament winding apparatus winds, around a workpiece, a fiber bundle formed by bundling a plurality of fibers. The filament winding apparatus includes a widening roller that rotates while making contact with the fiber bundle that is being conveyed. The widening roller has, provided on the peripheral surface, a plurality of projecting ridges extending in the axial direction, the projecting ridges being arranged side by side in the circumferential direction. The projecting ridges make contact with the fiber bundle to thereby widen the fiber bundle.

    Abstract: In a filament winding device and a filament winding method, when a band-shaped bundle is wound around a workpiece by way of hoop winding, a straight roller is selected, and the selected straight roller comes into contact with the band-shaped bundle. When the band-shaped bundle is wound around the workpiece by way of helical winding, a crown roller is selected, and the selected crown roller comes into contact with the band-shaped bundle.
