<p>PROBLEM TO BE SOLVED: To provide a method for forming a fiber-reinforced composite material having excellent compression strength after impact and interlaminar shear strength.SOLUTION: There is provided a method for forming a fiber-reinforced composite material in which curing is carried out at a curing temperature of 180°C or less using a prepreg containing the following constituent components (A), (B) and (C). The constituent component (C) is distributed near the surface at a concentration higher than the concentration at the inside of the prepreg. (A): a reinforcing fiber; (B) a base resin composed mainly of a thermosetting resin; and (C) fine particles of a polyamide 12 having a melting point of 180 to 190°C. The constituent component (B) is an epoxy resin prepared by using amines as a precursor, an epoxy resin prepared by using phenols as a precursor or an epoxy resin prepared by using a compound having a carbon-carbon double bond as a precursor.</p> |
