PURPOSE:To make it possible to mold a large panel of wide area quickly by such an arrangement wherein fibers for reinforcement are arranged in a molding space in advance and the space is evacuated, and then a main material and a hardening agent are mixed and the mixture is properly adjusted so that its viscosity and hardening time become less than specified values and the mixture is injected into the molding space. CONSTITUTION:A molding space 1 is formed by top force 2 and a bottom force 3 and one of the forces is equipped with a resin injection hole 7 at the rate of one per the area of the product of 1,500-4,000cm<2>, and in the molding space 1, fibers for reinforcement are arranged in advance, and a main material and a hardening agent are properly mixed so that its viscosity immediately after mixing becomes less than 200 cPs and its hardening time becomes within 10min at the temperature of injection liquid, and the mixture is injected through the injection hole 7 into the molding space which has been decompressed by evacuation and it is hardened. |
