    摘要: The invention concerns a method of moulding a part (1') made from composite material. This method comprises a step of injecting a liquid (7) under pressure into a closed mould (2) containing a fibrous pre-form (1) previously impregnated with resin. Said liquid (7) comes into contact with the resin but it is substantially inert and immiscible with respect thereto. The invention also concerns an apparatus for carrying out this method.
