Abstract: A high-pressure tank which is capable of improving the strength of a connecting part between a cylindrical part and a dome part is provided. A high-pressure tank 10 according to the present invention comprises: a liner 20 having a cylindrically-shaped cylindrical part 20a and hemispherically-shaped dome parts 20b which are continuous with both ends of the cylindrical part 20a; and a reinforcing layer 30 including a fiber bundle which is hoop-wound around the cylindrical part 20a of the liner 20 and a fiber bundle which is helically wound around the dome parts 20b thereof. An outer diameter of the end of the cylindrical part 20a is smaller than an outer diameter of a portion of the cylindrical part 20a which excludes the end.

Abstract: A filament winding apparatus includes a controller that controls the action of the filament winding apparatus. The controller includes a tension controller that controls a tension adjuster in such a way that an adjusted tension waveform that relates the rotation phase of a liner to the tension of a fiber adjusted by the tension adjuster has a phase opposite to the phase of a temporary tension waveform.

Abstract: A high pressure tank has a liner and a reinforcing layer. The reinforcing layer is formed on an outer surface of the liner. An adhesion inhibiting process that inhibits the liner from adhering to the reinforcing layer is applied to at least a portion of the liner in a region contacting the reinforcing layer.

Abstract: An object is to improve the strength of a high pressure tank that is manufactured by the filament winding method. There is provided a high pressure tank comprising a liner that forms an inner shell of the high pressure tank and includes a cylindrical portion in a cylindrical shape and dome portions in a curved shape that are extended from respective ends of the cylindrical portion; and a reinforcing layer that is formed by winding a fiber on an outer surface of the liner. Each of the dome portions is configured to have a predetermined curved shape that is different from an isotonic curve and that forms an isotonic curve in a process of winding the fiber on the dome portion by helical winding.
