Method for manufacturing high pressure tank

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.
