Procédé de fabrication d'une pièce en CMC

Procédé de fabrication d'une pièce en CMC L'invention concerne un procédé de fabrication d'une pièce en CMC avec une phase de consolidation comprenant du carbure de silicium et ayant un haut module de Young. Figure pour l'abrégé : Fig.2. The invention relates to a method for manufacturing a part made from CMC, the method comprising at least: - coating a plurality of cables (2) with an interphase by transporting the cables through a treatment chamber (4) into which a gas phase (10) is injected, the cables being tensioned during transport and the interphase being formed by vapour phase deposition from the injected gas phase; - forming a fibrous preform by three-dimensional weaving using the cables coated with the interphase; and- forming a consolidated fibrous preform by treating the fibrous preform by vapour phase chemical infiltration to form a consolidation phase on the interphase, the consolidation phase comprising silicon carbide and having a Young's modulus greater than or equal to 350 GPa and a part made from CMC comprising at least: - a 3D woven fibrous reinforcement comprising a plurality of cables (2), the cables having a plurality of fibres which are individually coated with an interphase; and- a consolidation phase densifying the fibrous reinforcement and located on the interphase, the consolidation phase comprising silicon carbide and having a Young's modulus greater than or equal to 350 GPa, the consolidation phase containing no free silicon.
