Abstract:
1. An RTM molding method in which a reinforcing fiber material is placed in a mold, a resin injection line and a suction line both communicatively connected to the interior of the mold are provided, the interior of the mold is reduced in pressure by suction and simultaneously a resin composition is injected into the interior of the mold to impregnate into the reinforcing fiber material to form an FRP molded body, the RTM molding method being characterized in that: the resin composition is a chain-curing resin composition; and after an initiation of the curing of the resin composition, the highest temperature at the curing head of the resin composition undergoing chain curing, within 10 seconds after the initiation of the curing, is increased so as to be the same as or higher than the heat-curing initiation temperature of the resin composition, and thus, the resin composition is chain-cured with a Vf of 41% or more.
