Title:
COMPOSITE-MATERIAL MOULDING METHOD AND MOULDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/063388
Kind Code:
A1
Abstract:
[Problem] To provide a composite-material moulding method and a moulding device which, while shortening moulding time, enable a pressing machine to be reduced in size by suppressing die clamping pressure. [Solution] In this composite-material moulding method, carbon fibres are 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. In the composite-material moulding method, the threshold value of the pressure in the cavity is set so as to be lower than the die clamping pressure, and, when the resin is injected into the cavity, an injection pressure equal to or greater than the die clamping pressure is applied to the resin to inject (S4, S5) the resin, until the pressure in the cavity reaches the threshold value. After the pressure in the cavity reaches the threshold value, suction is applied (S6-S9) to the cavity.
