Abstract (en)

[origin: WO2018002525A1] The invention relates to a process for manufacturing a composite part comprising a fibrous reinforcement and a ceramic matrix present in the porosity of the fibrous reinforcement, the process comprising at least the following steps: a) the formation of the fibrous reinforcement by three-dimensional weaving of ceramic yarns (step E1), the fibrous reinforcement thus formed having an interlock weave; b) the formation of a first ceramic matrix phase in the porosity of the fibrous reinforcement (step E4); c) the introduction into the porosity of the fibrous reinforcement, after carrying out step b), of a powder comprising a mixture of SiC particles and carbon particles (step E5); and d) the infiltration of the fibrous reinforcement obtained after carrying out step c) by an infiltration composition in the melt state comprising at least silicon so as to form a second ceramic matrix phase in the porosity of the fibrous reinforcement and thus obtain the composite part (step E6).
