This invention impregnates a fiber material the photocurable resin composition containing a vinyl ester resin (A), a urethane (meth) acrylic resin (B), and a photoinitiator (C), and winds the fiber material to the surface of a hollow container. After that, light of a wavelength in the visible light region and / or the ultraviolet light region is irradiated with a radiation intensity of 9 mW / cm 2 or more. According to this pressure vessel manufacturing method, a pressure vessel excellent in the balance of impact resistance, strength and heat resistance can be produced quickly. |
