| abstract |
The present invention is a method for producing a pressure vessel comprising impregnating a fiber material with a photocurable resin composition comprising a vinyl ester resin (A), a urethane (meth)acrylate resin (B), and a photoinitiator (C), winding the fiber material around the outer surface of a hollow vessel, and then irradiating light having a wavelength in the visible region and/or the ultraviolet region at an irradiance of 9 mW/cm 2 or more. With the method for producing a pressure vessel a pressure vessel having excellent balance among impact resistance, strength, and heat resistance can be rapidly produced. |
