    [0001] The invention relates to a method and a device for assembling a metal part with a composite part. The invention is more particularly, but not exclusively, dedicated to an assembly, according to a complete connection, between a support consisting of a composite material, in particular reinforced by continuous fibers, and a functional metal part, which assembly is requested by shear stresses and more particularly by torsion stresses. Some technical functions are difficult to achieve by the mere implementation of parts made of a composite polymer matrix material. Thus, for example, the joints and the joints between structural parts are preferably made of a metallic material for reasons of tribology, efficiency of the joint and resistance to the phenomena of degradation of the charged surfaces, in particular matting or lamination. flaking. Also, metal parts must then be assembled with structural composite parts. WO 2009 094595 discloses a device for assembling a metal part with a composite part whose assembly interface is subjected to shear stresses. This technical solution of the prior art uses projecting connecting elements on the assembly face of the metal part and which sink into the lamination of the composite material. These projecting elements provide a mechanical coupling of the metal part with the lamination to a depth of several folds, thus avoiding the phenomenon of peeling under the action of interface stresses. This embodiment of the prior art adapts a technique, known as the Anglo-Saxon "Z-pinning", which consists in introducing needles, made of metal or fibers, perpendicular to the layers of folds, to a depth significant of the lamination, which needles improve the resistance of said lamination to delamination. These are fine needles, whose length is of the order of 10 times the diameter, and which are able to be inserted between the reinforcing fibers without disorienting them excessively, which needles must be introduced during draping the composite part or the preform corresponding to this composite part, that is to say before impregnation of the resin folds or before the firing / consolidation of the matrix. The realization of the connection of such needles with the metal part is complex. Thus, US Pat. No. 5,972,524 recommends introducing the needles into the preform 302 and then welding the metal part to said needles. Documents EP 1 707 702 and US Pat. No. 4,808,461 recommend an ultrasound-assisted insertion of the needles in the green preform. These embodiments of the prior art require a thick composite part or the use of a large number of fine needles, and are not compatible with mass production. In addition, when the interface is stressed in shear, said needles tend to bend, so that they promote, under the effect of shear, the uncoupling of the two parts in a direction perpendicular to the interface. Thus, this type of assembly of the prior art often comprises two metal parts sandwiching the composite part, and between which the needles extend, thus constituting a double interface, which increases the mass of the device. WO 2010 101874 describes an example of connection between a composite part and a metal part, said assembly forming part of a seat of a motor vehicle, being subjected to torsional stress. According to this exemplary embodiment, a metal insert is integrated into the molding in a so-called intermediate piece made of a thermoplastic material. The metal insert has on some of its faces reliefs promoting mechanical coupling between said insert and the intermediate piece. The intermediate piece and the composite piece are made of melt-bondable polymers so that the intermediate piece, including the metal support, is intimately bonded to the composite part. The metal part is then fixed, by means of fasteners, to the metal support. The shape of the interfaces, substantially U-shaped, facilitates charge transfer and resistance to delamination. This method, which is satisfactory in actual use and production, remains complex to implement and its advantages in terms of mass are limited because of the presence of two metal parts extending over relatively high distances to ensure the transfer of load. and the safety of the device in the event of an accident. The invention aims to overcome the drawbacks of the prior art and for this purpose concerns a method for the structural assembly of a first piece made of a material comprising a polymer matrix with a second piece of metal constitution, by two surfaces facing each other, called assembly faces, according to an interface, which method comprises the steps of: a. forming on the assembly face of the metal part a form, said coupling shape, comprising two distant patterns having an extension in a direction normal to said assembly face; b. stamping the first part with the second part on the assembly interface while the matrix of the first part is in an unconsolidated state; vs. overmoulding on the assembly thus produced a so-called locking layer, the constitution of which comprises a polymer matrix, said locking layer comprising a portion overlapping the first and a portion overlapping the second part and opposing the relative displacement two parts in a direction normal to their assembly interface. Thus, the method which is the subject of the invention is produced economically and compatible with an implementation in series production, by the direct assembly of the metal part and the composite part during a stamping operation. The overmolding of the locking layer prevents the separation of the two parts in a direction perpendicular to the assembly interface, especially when said interface is subjected to a torsional stress or more generally to a shear stress parallel to the interface. This arrangement thus makes it possible to use less extensive coupling shapes in the direction perpendicular to said interface compared with Z-pinning type solutions of the prior art. Throughout the text, unless otherwise indicated, the terms "normal direction" refer to a normal direction inward or outward of the material surface. The invention is advantageously implemented according to the embodiments described below which are to be considered individually or in any technically operative combination. Advantageously, the coupling shape enters the first part during the stamping operation without passing through said part. Thus, the shaving of the coupling shape on the other side of the composite part is not necessary. According to one embodiment of the method which is the subject of the invention, step a) comprises an operation of welding or of additive machining on the assembly face of the metal part. This embodiment makes it possible to create a relief texturing of the assembly face in slender patterns capable of being inserted between the reinforcing fibers of the first piece when the latter is of a composite nature. The term "additive machining" refers to any method of depositing material on a substrate, including, but not limited to, laser sintering, molten powder sputtering, or laminated polymer deposition. According to another embodiment, compatible with the previous one, step a) of the method which is the subject of the invention comprises a cutting-stamping operation of the metal part. This embodiment is particularly economical in the context of mass production. Advantageously, the method which is the subject of the invention comprises, before step b), a step consisting in: d. interposing an adhesive layer between the joining faces of the two pieces. Thus the adhesive contributes to the stabilization of the metal part relative to the first part, in particular with respect to the phenomenon of uncoupling of said parts, and in particular when the material constituting the polymer matrix of the first part is not susceptible to stick to the metal constituting the second piece. Advantageously, the adhesive layer is of a nature to be thermally activated and step b) is carried out by heat-stamping, the activation temperature of the adhesive layer being adapted for its activation during the thermo-stamping operation. Thus gluing and stamping operations are combined for increased productivity. The invention also relates to an assembly comprising a first part made of a composite material with a polymer matrix and a second metal part, assembled according to faces, called assembly faces, facing one another in an interface, in which: i. the first piece consists of a composite comprising continuous reinforcing fibers in a thermoplastic matrix; ii. the second piece comprises, on its assembly face, a coupling shape, comprising a plurality of patterns, each pattern being of a closed contour in a plane parallel to the assembly face of said piece and extending according to a direction normal to said assembly face, the ratio between the extension of this pattern in a direction normal to the assembly face and the maximum diameter of the contour of said pattern in a plane parallel to the assembly face being less than 5. The low slenderness of the patterns of the assembly form allows the realization of this assembly by the economic method object of the invention without risk of buckling of said patterns during the stamping operation. In addition, this low slenderness limits the uncoupling phenomenon by the transverse rigidity of said patterns when the assembly interface is stressed by shearing parallel to said interface. Advantageously, the assembly face of the composite part is a flat surface. The device according to the invention thus makes it possible to form a torsion-resistant connection in a space of reduced thickness.
    [0002] Advantageously, the extension of the patterns of the coupling shape in a direction normal to the assembly face of the second part is less than the thickness of the first part. This configuration is more particularly adapted to the realization of the connection between the two parts by stamping According to a first embodiment of the assembly object of the invention, the assembly face of the second part comprises a plurality of patterns s' extending to the first piece in a direction normal to said assembly face. Thus, said patterns interact with the reinforcing fibers of the first piece to drain the forces at the interface in said piece. According to a second embodiment of the assembly object of the invention, compatible with the embodiment above, the assembly face of the second piece comprises a plurality of patterns extending towards the second piece in one direction. normal to said assembly face. Thus, during stamping, the polymer constituting the matrix of the first part and, if appropriate, the fold of said first part located closest to the assembly interface penetrates into said pattern.
    [0003] This link is less sensitive to the phenomenon of uncoupling. Advantageously, the plurality of patterns of the assembly face comprises a pattern comprising a stop portion, which stop portion is taken inside the composite part. Thus said stop portion stabilizes the assembly vis-à-vis the uncoupling phenomenon and contributes to transfer in the thickness of the composite part the normal stress at the interface, thus limiting the effects of punching or delamination.
    [0004] Advantageously, the assembly face of the second part comprises a plurality of patterns comprising an opening piercing said assembly face. These patterns make it possible to combine the advantages of the previous embodiments and are also achievable by a particularly economical cutting-stamping process for mass production.
    [0005] Advantageously, the assembly face of the second part comprises a plurality of patterns whose section parallel to the assembly face is variable in a direction normal to said assembly face. Thus, particular technical functions are integrated over the length of said patterns, in particular in the case of an assembly in which the plurality of patterns of the assembly face comprises a pattern comprising a portion, said stop, distant from the assembly interface which extends in a direction parallel to the assembly interface, which portion is adapted to perform a stop in a direction normal to said interface, in cooperation with the first part. This type of pattern contributes to the stabilization of the assembly vis-à-vis the phenomenon of uncoupling.
    [0006] For the same purpose, the object of the invention comprises, according to an advantageous embodiment: iii. a layer of material, called the locking layer, having a portion overlapping the first piece and a portion overlap on the second piece.
    [0007] According to an advantageous embodiment, the metal part comprises means capable of making a connection with a third part relative to said metal part. More particularly, said means are adapted to make an indexable pivot link with said third piece. The invention also relates to a seat, particularly for a vehicle, which seat comprises a mechanism comprising an assembly according to any one of the preceding embodiments and embodiments. Thus, said mechanism is introduced into a composite structure, that this composite structure is that of the seat or that of the vehicle comprising said seat, limiting the mass input. Advantageously, the means for adjusting the inclination of the backrest relative to the seat of the object of the invention comprise an assembly according to any one of the embodiments described above.
    [0008] The invention is explained below according to its preferred embodiments, in no way limiting, and with reference to FIGS. 1 to 7 in which: FIG. 1 shows in perspective and exploded view an embodiment of an assembly according to the invention, having an enlarged view of the assembly face of the second part; - Figure 2 shows the assembly object of the invention according to the example of Figure 1 and in a view from above; - Figure 3 shows, in a sectional view, different embodiments of patterns; - Figure 4 illustrates, in perspective views, Figure 4A exploded, Figure 4B after assembly, an embodiment of the object of the invention, the embodiment of which does not require the implementation of an operation stamping; - Figure 5 shows, in a perspective view, an embodiment of a metal part of an object of the invention according to a variant of the embodiment shown in Figure 4; FIG. 6 is a diagram illustrating an exemplary embodiment of the method that is the subject of the invention; - And Figure 7 is a partial sectional view showing the assembly of the composite part and the metal part after the stamping operation according to an embodiment of the method object of the invention. 1, according to an exemplary embodiment, the assembly (100) object of the invention is adapted to constitute an articulation between a plate (110) made of a composite material with fibrous reinforcement in a matrix consisting of a thermoplastic polymer , and a gusset (150) consisting for example of a metal plate. Said gusset is connected to the composite plate (110) via a metal part (120) which has a mechanical interface (121) for performing technical functions of the joint such as a pivot connection or an angular indexing , which mechanical part is, according to this embodiment, fixed by laser welding to a plate (122) comprising a face (123) of assembly with the piece (110) composite. Said assembly face (123) comprises coupling shapes consisting, according to this exemplary embodiment, of a plurality of cylindrical pins (124) substantially perpendicular to the assembly face. During the assembly, said pins (124) penetrate into the first piece (110). A layer (130), called the locking layer, made of a material comprising a polymer matrix, is overmolded on the assembly thus produced. According to nonlimiting exemplary embodiments, the composite part (110) consists of a laminating of plies of continuous fibers of carbon or polyamide glass, in a thermoplastic polyamide matrix with a thickness typically of between 3 and 10 mm. Figure 2, the layer (130) of locking covers the piece (110) composite and the piece (120) metal outside the assembly interface of these two parts. By way of non-limiting example, the locking layer (130) is made of an aliphatic polyamide, commonly referred to as "nylon", comprising a filler of short glass fibers and graphite. This material is known under trade names such as "Ertalon0", "CelstranO" or "Akulon0". Said layer is made by plastic injection on the assembled assembly. According to an application example this set is adapted to the achievement of a joint between the backrest 20 and the seat of a motor vehicle seat and its total thickness is limited to 20 mm. Still according to this application example, said assembly is able to support a torsion torque between the piece (120) metal and the first part (110) composite of 3000 N.m. 3, the patterns (124, 324, 334, 344, 354) constituting the coupling shape of the metal part of the assembly forming the subject of the invention are of a closed contour in a section parallel to the face (123) of assembly, that is to say that the contour of the section of said pattern is entirely comprised on the assembly face and does not intersect the edges of this assembly face. According to an exemplary embodiment, the cylindrical pin (124) is attached to the steel disc (122) by a MIG-MAG type welding process called "Cold Meta! Transfer "or CMT, described for example in the document US 2009 026188. According to another embodiment, the pin (324) comprises a portion (325), here a spherical portion, capable of stopping in a direction normal to the assembly face (123). According to an exemplary embodiment said pins (124, 334) are made of steel with a diameter of between 0.8 mm and 1.2 mm for a height of between 3 mm and 5 mm, so that this height is less than 1 mm. thickness of the composite part. By distributing 100 to 200 pins of this type on the face (123) of assembly of a disc (122) of 80 mm in diameter, said assembly between the first composite part and the second part supports a higher breaking torque than 3000 Nm According to another exemplary embodiment, the coupling shape comprises a pattern (334) in relief obtained by punching-folding the disk (122), which pattern comprises, according to this embodiment, a portion (335) inverted forming a stopping when assembling said disk (122) with the composite part. According to another embodiment, the coupling shape comprises a pattern (344) in relief consisting of a hole with dropped edges. Said falling edges are obtained directly during punching or by returning material by additive machining or welding.
    [0009] According to another exemplary embodiment, the coupling form comprises a relief pattern (354) constituted by a hole with dropped edges, said dropped edges of which are oriented towards the face opposite to the disc assembly face (123). (122) assembly. Thus, during the stamping of the metal part on the composite part, the matrix of the composite part being in the unconsolidated state, the polymer constituting said matrix and the first laminating layer are pushed into said hole (354) with fallen edges. Figure 4, the stamping is not exclusive mode of assembly of the piece (420) metal with the piece (410) composite. Thus, FIG. 4A, according to an exemplary embodiment of the assembly (400) which is the subject of the invention, the part (410) comprises slots (414) cut for example by high-pressure water jet. The piece (420) has metal on its face (123) assembly, patterns (334) in relief forming hooks. 4B, after said hook patterns (334) of the piece (420) metal have been introduced into the lumens (414) of the composite piece said pieces are moved relative to each other of a portion of a tower so as to lock the hook patterns in the slots (414) of the composite part (410). Then, overmoulding is performed on the assembly in order to stabilize the assembly.
    [0010] FIG. 5, according to a variant of the embodiment of FIG. 4, the patterns (534) of the coupling shape of the piece (520) made of metal, are made by cutting-stamping and comprise an opening piercing the disc (522) assembly and a locking loop (535). The implementation of this embodiment is similar to that of the previous mode, namely that said patterns (534) are introduced into the cut-out lights of the composite part and that the assembly is stabilized by the overmolding of the locking layer. FIGS. 4 and 5, according to these embodiments, the disk (422, 522) for assembling the metal part comprises, complementary to the reliefs (334, 534), slots (460, 560) cut, for example by punching, in which the material constituting the locking layer is introduced during the injection of said layer. Figure 6, according to an exemplary embodiment of the method of the invention, it comprises a first step (610) machining-forming consisting in creating the coupling shape on the assembly face of the metal part. This operation is, for example, carried out by a method of CMT type for welding a plurality of pins on the assembly face of the metal part without deforming the assembly disc. According to this embodiment, the matrix of the composite material constituting the first part of the assembly, consists of a thermoplastic polymer. Also in parallel with the step (610) of machining-forming, during a step (620) of composite manufacturing, the composite part is produced. According to this nonlimiting exemplary embodiment, said part is drawn in panoplie by high pressure water jet cutting, a consolidated plate of a thermoplastic matrix composite.
    [0011] During a tool preparation step (615), the machined metal part is placed in a stamping die, which stamping die is, according to this embodiment, mounted on the fixed table of a press . Depending on the intended stamping temperature of the composite part, said die is provided with a heating system by means known to those skilled in the art.
    [0012] During a transfer step (625), the composite part is placed on a transfer device, heating said part to a temperature close to the melting point of its polymer matrix at the same time as its delivery. to the press. By way of non-limiting example, the composite part is transferred to a transfer frame the now on its periphery and heated by its passage under radiant panels. During a stamping step (630), the metal part and the composite part are assembled. To this end the composite part is placed on the stamping die comprising the metal part, detached from its transfer frame and pressed into said die by a stamping punch of appropriate shape. Said punch and said stamping die make it possible to control the shape of the composite part during this operation. Reached at high temperature, the polymer matrix of the composite part is in a pasty state and the composite part is in a decompressed state. Thus, the localized displacements between the fibers, as well as interlaminar slips at greater distance are possible, so that the pins of the metal part penetrate into the assembly face of the composite part without generating a rupture. The composite part is then cooled in the stamping die, the punch and said die defining a volume which ensures the recompactage of said piece. Thus, the fibers are tightened on said pins during this compacting and consolidation. According to an optional step (629), an adhesive sheet constituted according to a non-limiting exemplary embodiment of an epoxy resin is inserted between the metal part and the composite part before stamping. Reached at the stamping temperature, said adhesive sheet tends on the one hand to crosslink and on the other hand to bind by diffusion with the thermoplastic matrix of the composite part and to adhere to the metal part. After demolding, the first and second parts of the assembly according to the invention are placed in a plastic injection mold. During a step (640) overmoulding, the locking layer is injected on this assembly in the form given to it by the injection mold. During a demolding step (650), after cooling, the assembly is demolded and finished during a finishing step (660), in particular to deburr the assembly and to carry out, if necessary, machining such as drilling and cutting, for the purpose of integrating the assembly object of the invention to a mechanical device.
    [0013] FIG. 7, according to an exemplary embodiment of the method that is the subject of the invention, the pins (124, 324) of the metal part, penetrate into the composite part (110) without passing through it, the height (720) of extension said pins relative to the normal direction to the assembly face (123) being less than the thickness (710) of the composite part (110). According to a non-limiting exemplary embodiment, the height (720) of said pins (124, 324) is of the order of half the thickness (710) of the composite part (110). The embodiments of the assembly object of the invention shown in Figures 2 and 4, are adapted to achieve the articulation of the backrest of a motor vehicle seat relative to the seat of said seat. This type of articulation is dimensioned in particular by resistance to torque criteria generated during strong accelerations observed in the event of an accident. Thus, each joint of this type must withstand a torque of 3000 N.m. In comparison with the prior art solution described in document WO 2010 101874, the assembly that is the subject of the invention makes it possible, at equal performance, to gain mass by almost 1 kg. The above description and the exemplary embodiments show that the invention achieves the desired objectives, in particular it allows the assembly of two pieces of different natures according to a simple plane-like interface and subjected to shear according to an automated manufacturing method and suitable for mass production. Although an application example presents the use of the assembly object of the invention for the realization of a seat, the person skilled in the art adapts the principles to other applications having constraints and functionalities of same nature.
