  • the present invention relates to a method of manufacturing a mechanical part comprising an insert of composite material of the type consisting of ceramic fibers in a metal matrix.
  • the invention applies to any type of mechanical part whose function is to transmit a traction force and / or compression mainly unidirectional.
  • some mechanical parts may comprise an insert made of composite material with a metal matrix, such parts being able to be monobloc.
  • a composite material comprises a matrix of metal alloy, for example titanium alloy Ti, within which fibers extend, for example ceramic fibers of SiC silicon carbide.
  • Such fibers have a much higher tensile and compressive strength than titanium. It is therefore mainly the fibers that take up the efforts, the metal alloy matrix ensuring a binder function with the rest of the part, as well as protection and insulation of the fibers, which must not come into contact with each other. others.
  • the ceramic fibers are resistant to erosion, but must necessarily be reinforced with metal.
  • the composite materials as described above are known to be used, in the aeronautical field, for the manufacture of disks, shafts, bodies of jacks, housings, spacers or as reinforcements of single-piece parts such as blades.
  • a technique for manufacturing these parts is described in the document FR 2886290 , representative of the technological background of the invention, in which one of the essential manufacturing steps consists in winding a bundle or a ply of coated wires around a circular part perpendicular to the axis of rotation of it.
  • the described parts thus obtained are of circular type and are particularly suitable for producing circular parts such as shafts, cylinder bodies, housings or discs.
  • connecting rods essentially oblong shape, whose function is to transmit a tensile force and / or unidirectional compression.
  • the invention particularly relates to a method of manufacturing a mechanical part comprising at least one composite material insert of the type consisting of ceramic fibers in a metal matrix capable of transmitting tensile forces and / or unidirectional compression between its ends .
  • the invention relates to a method for manufacturing a mechanical part according to claim 1.

  • the rod 1 has at each of its ends 13 and 14 a cylindrical recess 11 or 12 whose axes correspond to the parallel axes Z1 and Z2.
  • This type of rod 1 can be used, for example, in the design of the undercarriages or in that of turbomachines comprising rods for taking up thrust force.
  • the figure 2 represents an example of winding device 20 according to a first embodiment of the invention.
  • the winding device 20 is particularly suitable for producing an insert 3 for a mechanical part 10 or 110 such as a connecting rod.
  • This winding device 20 comprises a hollow part 2 of oblong shape acting as a mandrel and two flanges 21 and 22 of oblong and substantially identical shape.
  • the chuck part 2 has a geometry describing a closed structure most often curved.
  • the dimensions of the flanges 21 and 22 are greater than the dimensions of the mandrel part 2 so that the periphery 27 of each flange 21 and 22 extends beyond the periphery of the mandrel part 2.
  • the mandrel part 2 is sandwiched between the flanges 21 and 22.
  • the threads 32 are wound on the mandrel piece 2 when the winding device 20 is rotated along the winding axis Z.
  • the flanges 21 and 22 retain axially the son coatings 32 and guide them.
  • the winding device 20 belongs to an assembly forming a winding system.
  • the winding system further comprises means for rotating the winding device 20 and means for providing a bundle or a bonded sheet of coated threads 32.
  • the chuck part 2 comprises two rectilinear winding portions 24. These straight winding portions 24 are oriented perpendicular to the winding axis Z. Thus, at least a part of the winding of the wires 32 around the mandrel part 2 is performs in a rectilinear direction.
  • the winding of the coated wires 32 is carried out perpendicularly to the winding axis Z, in other words the coated wires 32 are substantially oriented perpendicularly to the winding axis Z.
  • these rectilinear winding portions 24 are parallel and interposed between two circular portions 25. It is possible to vary the dimensions of the chuck part 2, in particular its thickness in the axial direction Z, the length of the rectilinear winding portions 24 and the radius of curvature of the circular parts 25, depending on the dimensions of the desired insert 3.
  • the circular pieces 25 may also have different radii. Thus, the portions of rectilinear windings 24 may not be parallel.
  • the winding around the mandrel part 2 having rectilinear winding portions 24 makes it possible to generate in a short time an insert blank 33 comprising at least one rectilinear generator consisting of a large number of parallel and unidirectional coated wires 32.
  • the blank 33 of insert 3 once wound, can be removed from the winding device 20 by separating the flanges 21 and 22 from one another.
  • the shape of the blank 33 of insert 3 thus formed must be fixed to prevent the son 32 lose their orientation. Several techniques can be implemented for this purpose.
  • a first technique for maintaining the blank 33 of insert 3 consists in providing, at the beginning of winding, a step of winding a first metallic tinsel of attachment of the inner part of insert blank 33 3 and, at the end of winding, a step of winding a second metallic flashing 28 of attachment of the outer part of the blank 33 of insert 3.

  • Each notch 23 of the flange 21 is disposed vis-à-vis a notch 23 of the flange 22, thus forming a pair of notches 23.
  • the fixing of the metal straps 31 is facilitated by the dimensions of the notches 23 extending inwardly of the flanges 21 and 22 to a depth d.
  • the depth d of the notches 23 must be such that it is possible to access the hollow interior 29 of the chuck part 2 which is arranged around a hub of the winding device 20, not visible on the figure 2 , comprising an alternation of notches and teeth, the notches of the hub being in phase with the notches 23 of the flanges 21 and 22.
  • the depth d extends beyond the winding surface of the mandrel piece 2.

  • the metal straps 31 are made of a metallic material identical to that of the containers 4 and 104, described in connection with the figures 4 and 6 and the mandrel piece 2.
  • the metal straps 31 are fixed around the insert blank 33 by a contact welding process.
  • the metal straps 31 are arranged at regular intervals on the blank 33 wound insert 3.
  • a second technique for holding in the form of the blank 33 of insert 3, which does not require the use of straps 31, consists in providing a mandrel-forming piece 2 forming an oblong mandrel comprising at least one radial flange, for example with a section transverse L-shaped or U-shaped, on which the threads 32 are wound.
  • a bonded ply of coated threads 32 is used, it is possible to secure it to the mandrel piece 2 on which it is wound and to the ply. the lower layer by means of a method by contact welding between two electrodes and passage of a medium frequency current.
  • the wires 32 are thus welded as the winding progresses so that, when the insert blank 33 is extracted from the winding device 20, it forms a part integral with the mandrel part 2.
