Abstract: A method of fabricating a CMC part, includes coating a plurality of tows with an interphase by transporting the tows through a treatment chamber in which a gas phase is injected, the tows being tensioned during their transport and the interphase being formed by vapor deposition from the injected gas phase; forming a fiber preform by performing three-dimensional weaving using the tows coated with the interphase; and forming a consolidated fiber preform by treating the fiber preform by chemical vapor 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.

Abstract: A process for manufacturing a part made of composite material with a matrix at least predominantly made of ceramic includes producing a fibrous structure by three-dimensional or multilayer weaving; shaping the fibrous structure to form a fibrous preform core; depositing an interphase on the fibers of the preform core; consolidating the preform core by partial densification of the core including the formation of a matrix phase by chemical vapor infiltration or by a liquid process; depositing a powder of ceramic particles in the porosity of the preform core; draping one or more layers of pre-impregnated non-woven fibers over all or part of the outer surface of the preform core; heat treatment of the preform core and of the pre-impregnated layer(s) to form a hybrid fibrous preform; further densifying by infiltration of the hybrid fibrous preform with an infiltration composition containing at least silicon to obtain a ceramic matrix composite part.

Abstract: The invention relates to the production of a composite material of a lobed structure (10) of a flow mixer which comprises a portion having a plurality of lobes (17, 19). For this purpose, a fibrous preform containing a resin will be produced in a simple geometric configuration of developable revolution. This is an intermediate state. By exploiting the thermoformable or thermosetting nature of the resin, the geometry of this intermediate preform is modified to deform it with limited offsets towards the final geometry.

Abstract: A process for manufacturing a composite part includes arranging a fibrous preform in a mold including an impregnation chamber which includes in its lower part a filter by making a first face of the preform rest on the filter, the impregnation chamber being closed by a flexible membrane placed opposite a second face of the preform, the membrane separating the impregnation chamber from a compaction chamber. The process further includes injecting a compression fluid into the compaction chamber so as to apply a first pressure on the membrane and injecting a slurry including ceramic particles into the impregnation chamber with a second pressure while maintaining the injection of the compression fluid, the second injection pressure of the slurry being lower than the first pressure on the membrane.
