PURPOSE: To effectively arrange a matlike reinforced fiber without preforming the same, perform easily fiber-reinforcing of a large-sized tank and mold not only the large-sized tank under favorable circumstances but also a product having high rigidity in a manufacture of the large-sized tank made of fiber reinforced resin by reaction injection molding (RIM molding) or press molding. CONSTITUTION: In a manufacture of a large-sized tank made of fiber-reinforced resin by reaction injection molding (RIM molding) or press molding, prior to casting thermosetting resin raw materials into a mold, matlike reinforced fibers 32, 33 are arranged at least one by one so that they are positioned in a longitudinal direction, a right angle direction meeting with the direction and respectively from one end up to the other end of the developed unmolded tank structural body 31, and the resin raw materials are cast into the mold after that. |
