Abstract
A method for injecting ceramic particles into a fibrous texture includes placing a fibrous texture in a mould, injecting from one side a first suspension including a powder of large filtration particles to form a filtration layer, injecting from the opposite side a second suspension into the fibrous texture, the second suspension including a powder of small refractory ceramic particles, then draining through the filtration layer the liquid phase of the second suspension having passed through the fibrous texture and retaining the refractory ceramic particle powder inside the fibrous texture by the filtration layer of so as to obtain a fibrous preform including at least the fibrous texture filled with refractory ceramic particles and the filtration layer.
