When impregnation being done in the resin restoration body for fiber reinforced composite material production and the fiber reinforced composite material production

摘要

PPROBLEM TO BE SOLVED: To obtain a packed resin body in which an uncured resin for RFI (resin film infusion) molding having difficulty in film formation is subjected to RFI molding, and to provide a method for producing a fiber-reinforced composite material using the obtained packed resin body for RFI molding. PSOLUTION: In RFI molding, though the uncured resin film 5, which is impregnated into a reinforcing fiber or fiber woven fabric to give the matrix of a composite material, is formed into a film, the film is brittle and has weak strength and is packed into a baggy supporter composed of polyimide films 3 and 4. Since a great number of holes 7 are bored through at least one polyimide film 3, the uncured resin film 5 melted by rise in temperature flows out. The uncured resin film 5 having rigidity and difficulty in film formation is readily handled by packing/retaining the uncured resin film in the supporter 2 and is held in a fixed position/distribution.
