Abstract
A pressure vessel includes a vessel body and a fiber reinforced plastic layer formed on the surface of the vessel body, wherein the fiber reinforced plastic layer include fiber reinforced plastic in which reinforcing fibers are impregnated with plastic, a strand elastic modulus of the reinforcing fiber is 305 GPa or higher, and a tensile elongation of the reinforcing fiber is 1.45 to 1.70%. A carbon fiber for a pressure vessel has a strand elastic modulus of 305 GPa or higher and a tensile elongation of 1.45 to 1.70%.
Claims12
