PROBLEM TO BE SOLVED: To provide a resin transfer molding method capable of efficiently diffusing a resin without using a medium having to be disposed after molding, and a method for manufacturing a sandwiched laminated sheet. SOLUTION: The resin transfer molding method is constituted so that a fiber reinforcing material 1 having resin diffusing grooves 8 on its surface is laid on the inside of a mold, a bagging film 7 is superposed on the laid fiber reinforcing material to airtightly seal the peripheral edge of the bagging film to the mold and the space between the bagging film and the mold is evacuated to inject a resin in the mold. The fiber reinforcing material having the resin diffusing grooves on its surface and a core material are successively superposed on one surface of the mold and, after the bagging film is superposed on these materials, the peripheral edge of the bagging film is sealed to the mold airtightly to evacuate the space between the bagging film and the mold. Then, the resin is injected in the mold and cured by the resin transfer molding method. COPYRIGHT: (C)2004,JPO&NCIPI |
