PROBLEM TO BE SOLVED: To provide a method of manufacturing a fiber-reinforced plastic pressure vessel, the method achieving manufacture of a fiber-reinforced plastic pressure vessel having superior burst pressure, with high productivity.SOLUTION: The method of manufacturing a fiber-reinforced plastic pressure vessel is provided in which a filament winding is performed while epoxy resin composition is into reinforced fiber bundle 1 the monofilament of which has a denier of 1.0 dtex or more and 2.4 dtex or less and has a sectional shape perpendicular to a fiber axis having a roundness of 0.7 or more and 0.9 or less. It is preferable to use reinforced bundle composed of 14000 to 100000 monofilaments as reinforced fiber bundle or reinforced fiber bundle having a total denier of 14000 to 90000 dtex. As the reinforce fiber bundle, it is preferable to use reinforced fiber bundle in which a diameter Di of section perpendicular to a fiber axis of the reinforced fiber constituting the reinforced fiber bundle is 8 to 20 μm.SELECTED DRAWING: Figure 1 |
