1. A method for injecting a loaded suspension into a fibrous texture having a three-dimensional or multilayer weaving in which at least some of weft yarns link warp yarns on several layers of warp yarns or vice versa, said method comprising injecting a suspension containing a powder of solid particles into a volume of the fibrous texture, wherein the injecting of the loaded suspension is carried out by means of at least one hollow needle in communication with a loaded suspension supply device, each needle being configured to cross a thickness of the fibrous texture and move in at least one direction extending between a first face and a second opposite face of the fibrous texture so as to inject the loaded suspension at a plurality of determined depths in the fibrous texture as a result of the movement of the needle.
