PRODUCTION METHOD FOR FIBER-REINFORCED COMPOSITE MATERIAL |
摘要 |
A production method for a fiber-reinforced composite material comprises: a first step of stacking a prepreg including: a reinforcing fiber layer including reinforcing fibers and a resin composition with which the space between fibers of the reinforcing fibers is impregnated and a surface layer provided on at least one surface of the reinforcing fiber layer and containing polyamide resin particles having an average particle size of 5 to 50 μm and a melting point of 175 to 210° C. plurally and performing heating at a temperature of 120° C. or more and less than M1° C. when the melting point of the polyamide resin particles measured in the composition forming the surface layer is denoted by M1° C.; and a second step of performing heating at a temperature of M1° C. or more after the first step to cure the resin. |

1. A production method for a fiber-reinforced composite material comprising:
a first step of stacking a prepreg including a reinforcing fiber layer including reinforcing fibers and a resin composition with which the space between fibers of the reinforcing fibers is impregnated and which contains (A) a benzoxazine resin, (B) an epoxy resin, and (C) a curing agent having 2 or more phenolic hydroxy groups in a molecule and a surface layer provided on at least one surface of the reinforcing fiber layer and containing (A) a benzoxazine resin, (B) an epoxy resin, (C) a curing agent having 2 or more phenolic hydroxy groups in a molecule, and (D) polyamide resin particles having an average particle size of 5 to 50 μm and a melting point of 175 to 210° C. plurally and performing heating at a temperature of 120° C. or more and less than M1° C. when a melting point of the polyamide resin particles measured in the composition forming the surface layer is denoted by M1° C.; and a second step of performing heating at a temperature of M1° C. or more after the first step to cure the resin. |
