摘要:
The invention relates in particular to a method for impregnating a hollow fibrous texture, the method comprising at least the following steps: injecting a first suspension (10) comprising a first powder of solid particles made of ceramic or carbon material into an inner space (2) defined by an inner surface (1a) of a hollow fibrous texture (1) placed in a mould, an outer surface (1b) of the fibrous texture (1) being presented opposite a wall (3) of the mould; and impregnating the fibrous texture (1) with the first suspension (10) by centrifugal force, by rotating the mould on itself, varying the speed of rotation of the mould during the impregnation of the texture (1) with the first suspension (10).

The invention relates to an assembly of two parts (2, 4), one of the parts (4) being made of a composite material having a fibrous reinforcement obtained from a fibrous preform created by means of three-dimensional weaving and densified by a matrix. The assembly includes a mechanical anchoring element (12) that is secured to one of the parts and inserted inside the other part.
