| description | The invention relates to a method for manufacturing a part made of SiC/SiC composite material, the method comprising: * producing a fibrous preform from silicon carbide fibres; * depositing an interphase onto the fibres the fibrous preform; * performing a first densification step comprising the formation of a first matrix phase by chemical vapor infiltration with a first matrix precursor containing methyltrichlorosilane (MTS); * performing a second densification step comprising the formation of a second matrix phase by chemical vapour infiltration with a second SiC precursor that differs from said first precursor, the second precursor forming a SiC deposit comprising residual hydrogen and free silicon; * performing a third densification step comprising the impregnation of the fibrous preform with an impregnation composition containing at least silicon so as to obtain a part made of SiC/SiC composite material. |
