  • Process for manufacturing a ceramic composite material part by pressurized injection of a loaded slurry into a porous mould
    Patent number: 10954169
    Abstract: A method of fabricating a composite material part includes injecting under pressure a slurry containing a powder of refractory ceramic particles into a fiber texture; and draining the liquid of the slurry that has passed through the fiber texture, while retaining the powder of refractory ceramic particles within the texture to obtain a fiber preform filled with refractory ceramic particles. The injection tooling includes a porous material mold including an internal housing in which the fiber texture is placed, the slurry being injected into the fiber texture via an injection port in the injection tooling and leading into the internal housing of the mold. The tooling includes a rigid material enclosure in which the porous material mold is held while the slurry is injected under pressure and while the liquid of the slurry is drained, the liquid of the slurry being discharged via a vent present in the enclosure.
