RTM MOLDING DEVICE, RTM MOLDING METHOD, AND SEMI-MOLDED BODY

摘要

The objective is to provide an RTM molding device and an RTM molding method by which even a large member and a thick plate member can be impregnated with a resin without causing non-impregnatlon, fiber meandering, etc., and a high-tough-ness and high-precise molded body can be obtained. In an RTM molding device (100), a fiber-reinforced base material (11) is provided on at least one side surface thereof with: a surface molding layer (4) which is arranged between the fiber-reinforced base material (11) and a molding die (1), comprises a plurality of through holes (7) formed therein, and has a stiffness so that when the in-side of the cavity is depressurized, the thickness does not substantially change under the pressure in a cavity; and a resin diffusion portion (5) which is located on the side of the surface molding layer (4) opposite to the side of the fiber-reinforced base material (11), and comprises a resin flow path formed to communicate with the plurality of through holes (7) of the surface molding layer (4).
