Beschreibung
Zusammenfassung:	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. L'invention concerne un procédé de moulage d'une pièce (1') en matériau composite. Ce procédé comprend une étape d'injection d'un liquide (7) sous pression dans un moule fermé (2) contenant une préforme fibreuse (1) préalablement imprégnée de résine. Ledit liquide (7) vient au contact de la résine mais il est sensiblement inerte et non miscible avec celle-ci. L'invention concerne également un appareil pour mettre en oeuvre ce procédé.
