The invention relates to a method for making a mechanical part (10) that comprises 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 comprising a ceramic fibre coated with a metal sheath, wherein said method comprises the production of at least one insert (3) with the step of winding a bundle or a bonded web of coated threads (32) around a revolution part (2). According to the invention, at least a portion of the winding is carried out in a rectilinear direction. 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) 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'au moins un 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). Selon l'invention, au moins une partie du bobinage s'effectue selon une direction 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.
