<P>PROBLEM TO BE SOLVED: To provide a method for vacuum impregnation molding of FRP products and a device for manufacturing them for stably molding high quality FRP products by preventing generation of voids during resin impregnation, by preventing resin from flowing out of a vacuum bag after resin impregnation is completed, and by maintaining vacuum inside the vacuum bag until the resin is gelated and immobilized. <P>SOLUTION: In the method for vacuum impregnation molding of the FRP product, a laminate 2 including reinforced fiber fabric 2a is placed on a mold 1; the laminate 2 is air-tightly covered with a vacuum film 14; and the laminate 2 is impregnated with resin under vacuum. The laminate 2 is covered with a breather 4 used as a resin diffusion medium. A resin diffusion supply pipe 5 used as a resin gate is arranged on one side of the breather 4. A first degassing tube 8 used as a vacuum port and a degassing bag 9 formed of waterproof moisture permeable fabric are arranged on the other side of the breather 4. When the resin is impregnated, only gas is exhausted through the first degassing tube 8 and the degassing bag 9. <P>COPYRIGHT: (C)2012,JPO&INPIT |
