WIPO Patent Application WO/2016/063387

Kind Code:

A1

Abstract:

[Problem] To provide a composite-material moulding method and a moulding device which, while shortening moulding time, enable die clamping pressure to be suppressed. [Solution] In this composite-material moulding method, a reinforcing base material is disposed in a cavity in a moulding die capable of being opened and closed, a resin is injected into the cavity while a die clamping pressure is in a state of being applied to the moulding die, and the resin is cured to mould a composite material. When the resin is injected into the cavity, the injection pressure of the resin is adjusted so as to be between a first pressure which is higher than the die clamping pressure, and a second pressure which is lower than the die clamping pressure, and the injection pressure of the resin is lowered (S3-S6) from a pressure higher than the die clamping pressure to a pressure lower than the die clamping pressure at least once. As a result, the resin is injected (S7) without the pressure in the cavity exceeding the die clamping pressure from the start of resin injection to the end of resin injection.
