Abstract: A method for manufacturing a part made of ceramic matrix composite (CMC) material includes producing a fibrous preform from silicon carbide fibres; consolidating the fibrous preform by gas-phase chemical infiltration; injecting a slurry including a silicon carbide particle powder into the consolidated fibrous preform; and densifying by infiltrating the preform with a composition based on molten silicon to give a part made of CMC material. The slurry further includes at least one organic binder. The method includes, prior to the infiltrating of the preform with a composition based on molten silicon, pyrolysing the organic binder so as to form a carbon-containing residue in the fibrous preform.
