PURPOSE: A manufacturing method of fiber reinforced plastics for a vessel is provided to manufacture an FRP(Fiber Reinforced Plastics) molding product by creating a vacuum and processing in a thermosetting property between an outer surface of a mold and a vacuum bag of a vacuum generating unit when inputting the mold in which the vacuum generating unit is installed. CONSTITUTION: A manufacturing method of an FRP molding product for a vessel comprises a process A(101), a process B(102), a process C(103), a process D(104), a process D(104), a process E(105), a process F(104), a process G(107), and a process H(108). A form is manufactured as a form of the FRP molding product in the process A. A releasing agent is coated on an outer surface of a mold in the process B. A dry preg is formed by bonding a reinforced fiber to an epoxy resin film in the process C. A venting sheet is bonded on an upper surface of a separating film and an edge of the dry preg laminated in plurality of layers in the process D. A vacuum pump discharging air inside a vacuum bag to the outside is connected to an air discharging pipe installed in the other end in the process E. The dry preg is cured with heat by heating a thermal curing furnace in the process F. The FRP molding product is taken off from the mold in the process G. The separating film in an upper part of the FRP molding product, the venting sheet, and a burr generated in the edge of the FRP molding product are removed in the process H.
