Abstract

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.

Abstract

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.
