Abstract: A fibrous texture includes a stack of at least first, second, third and fourth unidirectional plies. The first, second, third and fourth plies each respectively include a first plurality of rovings aligned in a first direction, a second plurality of rovings aligned in a second direction different from the first direction, a third plurality of rovings aligned in a third direction different from the second direction and a fourth plurality of rovings aligned in a fourth direction different from the third direction. The rovings of the first plurality of rovings being spaced apart from each other by a given distance in a direction perpendicular to the first direction. The rovings of the second plurality of rovings are spaced apart from each other by a given distance in a direction perpendicular to the second direction.

Abstract: A method for coating fibers, includes desizing sized short fibers having an average length less than or equal to 5 mm, the short fibers being made of ceramic material or carbon, sieving the desized short fibers in order to separate them from any agglomerates of sized short fibers still present, introducing the desized and sieved short fibers into a reactor, and coating the short fibers in the reactor by chemical vapor deposition in a fluidized bed.

Abstract: A method for injecting a loaded suspension into a fibrous texture having a three-dimensional or multilayer weaving includes the injection of a suspension containing a powder of solid particles into the volume of the fibrous texture. The injection of the loaded suspension is carried out by at least one hollow needle in communication with a loaded suspension supply device, each needle being movable 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 one or more determined depths in the fibrous texture.
