Title:
PRODUCTION METHOD FOR FIBER-REINFORCED COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2014/157099
Kind Code:
A1
Abstract:
A production method for a fiber-reinforced composite material is provided with: a first step in which a plurality of layers of a prepreg are stacked, said prepreg being provided with a reinforcing fiber layer that comprises reinforcing fibers and a resin composition that is used to impregnate the area between the reinforcing fibers and that comprises (A) a benzoxazine resin, (B) an epoxy resin, and (C) a curing agent that has two or more phenolic hydroxyl groups in the molecule thereof, and a surface layer that is provided on at least one of the surfaces of the reinforcing fiber layer and that comprises (A) the benzoxazine resin, (B) the epoxy resin, (C) the curing agent that has two or more phenolic hydroxyl groups in the molecule thereof, and (D) polyamide resin particles that have an average particle size of 5-50 µm and a melting point of 175-210 °C, after which the result is heated at a temperature of 120 °C or higher but less than M1 °C, wherein M1 °C represents the melting point of the polyamide resin particles as measured within the composition that constitutes the surface layer; and a second step in which resin curing is performed by heating after the first step at a temperature that is equal to or higher than M1 °C.
