Definitions
- the present invention relates to the manufacture of a metal part by the technique of hot isostatic compression of a preform formed of a fibrous structure comprising metal son with optional insertion of reinforcements based on ceramic fibers.
- the invention aims in particular at producing a reinforcement piece for large blades of organic composite material, such as turbojet fan blades or propeller blades.
- this reinforcing piece attached to the blade of composite material, extends in a direction substantially radial with respect to the axis of rotation of the fan rotor, along the leading edge. It extends on both sides of the leading edge on a portion of the intrados and extrados faces tapering downstream. It has a cross section in the shape of "C" with a relatively thick central branch and tapered lateral branches. The profile of the reinforcing pieces is also twisted and arched between the foot and the head of the blade which it follows the so-called three-dimensional shape.
- the Applicant has developed a method of manufacturing a piece of this type comprising a step of producing at least one fibrous structure by three-dimensional weaving of metal son followed by the submission of the fibrous structure to hot isostatic pressing causing compaction and diffusion bonding of the metal wires so as to obtain a massive piece.
- the metal son are advantageously drawn wire son.
- the three-dimensional weave makes it possible to shape the fibrous structure with the imprint of a tool and thus to obtain a piece with complex geometry.
- wire of different diameters can be used depending on the thickness at a given location.
- the fibrous structure may comprise composite son or coated son made of a ceramic fiber, such as SiC, coated with a metal alloy such as a titanium alloy.
- the invention relates to an alternative embodiment of the previously deposited method.
- the method of manufacturing a metal part by producing a structure with a fibrous structure of metal fibers and submitting the preform to hot isostatic pressing in a tool to obtain a massive piece, the tooling comprising at least a first element with a mold cavity of the part, is characterized in that the first tool element is of elongate shape along a direction XX between two ends, the fibrous structure is produced at least in part by winding at least one wire around said first member along said direction from one end to the other.
- the method allows the possible incorporation of fibrous structure elements formed by three-dimensional weaving of metal and / or composite son.
- the piece is obtained from a first elongated tool element along a first direction.
- the fibrous structure obtained by the winding of wire around said direction, from one end to the other of the first element, makes it possible to produce a part having a variable thickness along the first direction.
- the solid piece is advantageously a turbojet fan blade reinforcing edge.
- the composite yarns are then preferably disposed along the part of the part forming the leading edge.
- FIG. 1 represents, in perspective, an example of a turbojet fan blade equipped with an example of a reinforcing piece
- Figure 2 shows in perspective the reinforcing piece
- Figure 3 shows schematically the winding mode of a wire around the first tooling element
- Figure 1 shows a blade 1 of a turbojet fan. It comprises a foot 2 by which the blade is fixed to the rotor of the machine. This is extended by a blade aerodynamic profile, in a radial direction relative to the axis of rotation of the fan.
- the blade 4 has a lower face 8 and an extrados face 6 extending between the leading edge 10 upstream and the trailing edge 12 downstream (with respect to the gas flow).
- Reinforcing pieces may be fixed on the body 7 of the blade at the trailing edge and especially at the leading edge 10 to prevent or delay their deterioration, especially in case of impact.
- a reinforcing piece 20 is fixed on the body 7 of the blade, itself made of organic composite material, at the leading edge 10 thereof.
- the leading edge 10 is formed at least in part by the reinforcing piece 20 which conforms to the general shape of the blade.
- the fan blade of FIG. 1 is of three-dimensional shape, being twisted along its longitudinal direction and transversely arched.
- the reinforcing piece 20 is also of complex shape as can be seen in FIG.
- the reinforcing piece extends longitudinally along a first direction A and has a cross section in a plane P perpendicular to this direction, a central portion 22 of relatively large thickness extended by tapered branches 24.
- the reinforcing piece 20 thus has a longitudinal central portion 21 of substantial thickness laterally lined by two longitudinal sides 23 thinned towards their distal edge.
- the outer face 24E of the flanks 23 comes in the continuity the outer surface 22E of the central portion forms the leading edge 10 of the blade, once the reinforcing piece 20 fixed on the body 7 of the blade.
- a method of manufacturing a workpiece such as the reinforcement piece 20 is now described. While the method described in the patent application FR 10 57799) comprises the preparation of a preform with a fibrous structure obtained by weaving yarns. metal associated with coated son, said preform being disposed in a tool comprising a first element and a second tool element, the method of the invention consists essentially in the development of a preform with a fibrous structure obtained by winding of wire.
- FIG. 3 diagrammatically shows a first tool element 51, preferably a superalloy, one face of which forms part of the tooling cavity.
- This first element of the tool 51 is of elongated shape in a direction XX which is here an axis XX, with an imprint corresponding to the shape of a part of the part to be obtained; it is provided with holding blocks 51 A at its ends.
- the profile is here shaped for the realization of a blade 20 of blower blade.
- a preform 25 is made by winding a wire 36 around the tooling element 51.
- the yarn is unwound from a reel not shown in the figure.
- the winding can be carried out by turning the element 51 about its axis XX while arranging the wire with respect to this axis so that it is always properly oriented, here perpendicular to the tangent to the curve of the edge. 'attack.
- the wire 36 used is advantageously a drawn wire of titanium alloy.
- the wire may be single or it is possible to wind son of different diameters depending on the desired thicknesses on certain areas of the preform. Reinforcements may be incorporated into the preform by being held in place by the wire windings.
- a composite wire insert 38 may be disposed along the element in the area to be reinforced, such as the leading edge of the blade.
- These composite yarns comprise a ceramic core fiber 39, for example silicon carbide (SiC) coated with a metal alloy such as a titanium alloy or an aluminum alloy in the case of an aluminum wire.
- reinforcements that may be incorporated are inserts and / or preforms based on coated composite wires such as SiC-Ti, SiC-Al SiC-SiC,
- the preform may comprise strips based on Ti, Al TiAl or any other compatible material having properties that may allow superplastic forming and diffusion welding.
- the first tooling element 51 with the preform 25 is disposed in a second tooling element 52 with an impression adapted to conform the part.
- the set of two elements 51 and 52 forms the tooling 50. This could be formed of several tooling elements of which at least one is the first element around which the fiber preform is wound.
- the preform 25 is compacted in the tooling 50 supplemented by a suitable lid in an isothermal press or autoclaved bag by vacuum isostatic compression treatment under vacuum: for example, it is maintained at 940 ° C for 120 minutes under a pressure of 1000 bars.
- This metal piece includes reinforcements 39 ceramic.
- a pair of reinforcing pieces is produced by winding a wire around two first tooling elements assembled along a mandrel. This arrangement makes it possible to optimize the manufacturing and reduce the manufacturing cost.
