Abstract
A method for producing a part made of composite material, includes obtaining a mold includes (i) a fibrous texture, (ii) a granular filtration layer located between a drainage surface of the texture and a permeable discharge surface and including a powder of filtration particles, and (iii) an element for retaining the granular layer, which element is distinct from the layer and located between the permeable discharge surface and the drainage surface, introducing a suspension including matrix particles in a liquid medium through an introduction surface of the fibrous texture that is distinct from the drainage surface, the liquid medium passing through the drainage surface, the granular filtration layer and the retention element to be discharged through the permeable discharge surface, and the matrix particles being retained in the pores of the fibrous texture by the granular filtration layer, and forming the part made of composite material by forming a matrix.
