Abstract
A method of impregnating a fiber texture of hollow shape, the method including introducing a first suspension containing a first powder of solid particles of ceramic or carbon material into an inside volume defined by an inside face of a fiber texture of hollow shape placed in a mold, an outer face of the fiber texture being presented facing a wall of the mold; and using the action of centrifugal force to impregnate the fiber texture with the first suspension by causing the mold to rotate and varying the speed of rotation of the mold during the impregnation of the texture with the first suspension.

A method of impregnating a fiber texture of hollow shape, the method comprising:
- introducing a first suspension containing a first powder of solid particles of ceramic or carbon material into an inside volume defined by an inside face of a fiber texture of hollow shape placed in a mold, an outer face of the fiber texture being presented facing a wall of the mold;
- and
- using the action of centrifugal force to impregnate the fiber texture with the first suspension by causing the mold to rotate and varying the speed of rotation of the mold during the impregnation of the fiber texture with the first suspension.

- using the action of centrifugal force to impregnate the fiber texture with the first suspension by causing the mold to rotate;
- after the fiber texture has been impregnated with the first suspension, introducing a second suspension into the inside volume, the second suspension including solid particles of ceramic or carbon material, and being different from the first suspension;
- and
- using the action of centrifugal force to impregnate the fiber texture with the second suspension by causing the mold to rotate, the impregnation of the fiber texture with the first suspension and the impregnation of the fiber texture with the second suspension being performed at different speeds of rotation of the mold.
