  • Patent number: 10507999
    Abstract: There is provided a manufacturing method of a tank. The manufacturing method comprises a cooling process of cooling down a resin-adhering fiber bundle that has a resin adhering to a fiber bundle; and a winding process of winding the resin-adhering fiber bundle that is cooled down by the cooling process, on a rotating liner. The cooling process cools down the resin-adhering fiber bundle to make a temperature of the resin-adhering fiber bundle that is being wound on the liner in the winding process, equal to or lower than a set temperature which is set in advance as a temperature to provide a viscosity of the resin that prevents the resin from being splashed from the resin-adhering fiber bundle by rotation of the liner in a course of winding the resin-adhering fiber bundle on the liner.
