    摘要： The present invention relates in particular to a process for manufacturing an impregnated fibrous assembly, the process comprising at least the following steps: - introducing a first suspension (10) comprising a first powder of solid particles into an internal volume (2) delimited by an inner face (1a) of a first fibrous texture (1) of hollow shape placed in a mould, an outer face (1b) of the first fibrous texture (1) being present facing a wall (3) of the mould, - impregnating, by action of the centrifugal force, the first fibrous texture (1) with the first suspension (10) by rotating the mould about itself, - positioning, after impregnation of the first texture (1) with the first suspension, a second fibrous texture on the inner face (1a) of the first fibrous texture (1) in order to obtain a fibrous assembly, - introducing a second suspension comprising a second powder of solid particles into the internal volume (2) after positioning the second fibrous texture, and - impregnating, by action of the centrifugal force, the second fibrous texture with the second suspension by rotating the mould about itself in order to obtain the impregnated fibrous assembly.
