Patent

CA 2694544

The invention relates to a method for making a mechanical part (10, 110) including at least one insert (3) made of a composite material with a metal matrix in which extend ceramic fibres, the composite material insert (3) being obtained from a plurality of coated threads (32) each including a ceramic fibre coated with a metal sheath, wherein the method comprises the production of a preform (33) of the insert (3) with the step of winding a bundle or a bonded web of coated threads (32) around a revolution part (2, 202). According to the invention, a portion at least of the winding is carried out in a rectilinear direction. The method further comprises: the step of inserting the insert (3) preform (33) in a first container (4); the step of isostatic hot compaction of the first container (4); and the step of machining the first container (4) in order to form a rectilinear insert (3). The invention also relates to a mechanical part (10) thus obtained and to a winding device (20) adapted for implementing the production method of the invention.

L'invention concerne un procédé de fabrication d'une pièce mécanique (10, 110) comportant au moins un insert (3) en matériau composite à matrice métallique au sein de laquelle s'étendent des fibres céramiques, l'insert (3) en matériau composite étant obtenu à partir d'une pluralité de fils enduits (32) comportant chacun une fibre céramique enrobée d'une gaine métallique, le procédé comprenant la fabrication d'une ébauche (33) d'insert (3) avec une étape de bobinage d'un faisceau ou d'une nappe liée de fils enduits (32) autour d'une pièce de révolution (2, 202). Selon l'invention, au moins une partie du bobinage s'effectue selon au moins une direction rectiligne. En outre, le procédé comprend : une étape d'insertion de l'ébauche (33) d'insert (3) dans un premier conteneur (4); une étape de compaction isostatique à chaud du premier conteneur (4); et une étape d'usinage du premier conteneur (4) pour former un insert (3) rectiligne. L'invention concerne également une pièce mécanique (10) ainsi obtenue et un dispositif de bobinage (20) conçu pour la mise en oeuvre du procédé de fabrication selon l'invention.
