    [0001] The invention relates to a method and an apparatus for automatically manufacturing a vacuum assembly for the manufacture of a fiber-reinforced composite part made by hardening. of a matrix material infused into a fiber-based material, using a vacuum assembly.
    [0002] Parts made of a fiber reinforced composite material, namely fiber-reinforced composite parts, are today essential in the aeronautical and aerospace field. But the use of such materials is also increasingly popular in the automotive field. Particularly stressed structural elements are manufactured with a minimum weight of fiber-reinforced plastics, because of the high strength and stiffness of these materials, per unit weight. Thanks to the anisotropic properties resulting from the fiber orientation of the fiber-reinforced composite materials, the parts can be adapted to local loads or constraints, thus allowing an optimal exploitation of the material in the optics of a lightened construction. A manufacturing method frequently used in practice to manufacture fiber-reinforced composite parts is the so-called open-mold process, according to which fiber-based material is introduced into a setting tool. shaped and sealed to the air (relative to the atmosphere) by means of a vacuum assembly. The fiber-based material sealed under the vacuum assembly is then evacuated. When dry fiber semi-products are used, matrix material is then infused to impregnate the fiber material with the matrix material. When using prepregs, ie semi-products based on pre-impregnated fibers, the fiber-based materials are already infused with the matrix material. By curing the matrix material, there is a bond between the fiber base material and the matrix material, thereby producing the fiber reinforced composite part. In part, also under the vacuum assembly, parts or surfaces of previously hardened parts are used, thereby producing special structural elements. Such a vacuum assembly generally comprises a plurality of material layers, each consisting of different materials and thus respectively forming different functional layers, depending on the manufacturing technology. The functional layers formed by the layers of material here must each provide a specific function in the overall manufacturing process, to enable a fiber-reinforced composite part to be reliably manufactured, for example by the so-called open-mold or open-mold process. mold or generally by the vacuum curing process. Such layers of material, which are often used in practice, may for example be a vacuum sheet, a suction nonwoven, a flow aid, a separator sheet, a fabric of tear and / or a vacuum sealing strip. In addition, it is possible to apply special auxiliary means for sealing the vacuum assembly relative to the atmosphere. The manufacture of the vacuum assembly is generally carried out by skilled personnel, that is, by hand, particularly in the case of large parts made of fiber-reinforced composite materials. huge costs because of the significant amount of time spent doing the vacuum assembly. The vacuum assembly here must always be built step by step, that is to say, it is only after the introduction of the fiber-based material into the forming tool, that the Individual layers of material of the vacuum assembly can be introduced and fixed stratum after layer or layer after layer, ultimately forming the complete vacuum assembly with the fiber-based material enclosed therein. Depending on the method or procedure used, the order of the individual functional layers may differ. Both the cutting of the individual material layers, and the draping of the layers of material in the forming tooling for the manufacture of the vacuum assembly, not only constitute a high cost factor, but also a major source of error that can lead to the disposal of the entire room. Particularly in the case of large aeronautical and aerospace parts, a defective vacuum assembly may lead to scrapping of the workpiece, because in the context of strict quality requirements, defects are only tolerated under certain conditions. . Accordingly, the object of the present invention is to provide an improved method for making such a vacuum assembly for the manufacture of a fiber reinforced composite part, thereby reducing the error rate and leading to improved production. 3028448 set 3 manufacturing process with a quality guarantee. An object of the present invention is also to indicate a corresponding installation for the manufacture of such a vacuum assembly.
    [0003] This object is achieved by a method for automatically manufacturing a vacuum assembly for the manufacture of a fiber reinforced composite member made by curing a matrix material infused with based on fibers, using a vacuum assembly, a plurality of non-fabricated material layers being provided and prepared for the vacuum assembly by a material supply and preparation device, characterized in that the layers of material are mounted together layer by layer, automatically, by a mounting device to form a pre-assembled vacuum assembly, the material layers being made by a cutting device before, during or after mounting, depending geometric data prescribed. In accordance with the invention, there is provided a method for automatically manufacturing a vacuum assembly for the manufacture of a fiber reinforced composite part made by curing a matrix material infused with a base material. of fibers, using a vacuum assembly. For the automated manufacture of the vacuum assembly, several layers of unassembled material for the vacuum assembly are provided and prepared by a material supply and preparation device. The material layers here correspond to the individual layers of material for the manufacture of the vacuum assembly and thus form the individual functional layers. The individual material layers herein may each comprise different materials to thereby form the individual functional layers of the vacuum assembly. The material supply and preparation device supplies and prepares the unbound material layers, for example in web form, the different material layers being wound on rolls and provided in this form.
    [0004] Uncoated material layers are understood to mean the supply and the preparation of the respective material of the layers of material, so that these layers of material are not yet cut to the required dimensions and geometry, that is to say That the individual material layers have not yet been made. In accordance with the invention, it is now provided that the layers of material are automatically assembled layer by layer by a mounting device to form a pre-assembled vacuum assembly, the layers of material being made by a cutting device before, during or after mounting, according to prescribed geometrical data.
    [0005] The layers of material supplied and prepared by the material supply and preparation device, for example supplied in the form of strips, can thus be fed, for example by way of return rollers, to the mounting device where they are mounted together layer by layer. The mounting of the individual material layers is done here on the sides forming the faces of the short films of material, thus leading to the assembly of evacuation with the respective different functional layers.
    [0006] In order for the future vacuum assembly to be adapted to the forming tool or to the workpiece to be produced, the non-fabricated material layers are cut by a cutting device according to the prescribed geometrical data, and are Therefore, after the automated manufacture of the vacuum assembly, the result is a pre-assembled vacuum assembly consisting of individual material layers. which each form a functional layer. The cutting of the layers of material by the cutting device can take place before, during or after the mounting of the layers of material. It is thus possible, for example, for the layers of material that are not made to be made by the cutting device before the individual material layers are assembled, and for the layers of material thus produced to be assembled together by the mounting device. However, it can also be envisaged that the entire vacuum assembly is first made by mounting the individual material layers and then made by the cutting device. In a third variant, it is possible, for example, to start by assembling together and cutting off certain individual material layers, the material layers thus produced and assembled together being then assembled together to form the assembly 3028448 5 of the assembly assembly. under vacuum. This is advantageous, for example when different layers of material have different dimensions or geometries, which can not be manufactured during a common making step.
    [0007] According to this method, it is thus possible to manufacture a vacuum assembly in an automated manner, that is to say to assemble the individual functional layers together and to make them appropriately, in an automated manner. Compared with the manual manufacturing method, the automated method according to the invention offers the advantage of not requiring manufacture of the vacuum assembly directly at the parts manufacturer, but to allow manufacture, for example by an external manufacturer. The automation of the process makes it possible to reduce errors during the laying of the layers and thus to manufacture a vacuum assembly with reproducible quality. In addition, it is possible to significantly lower manufacturing costs, especially large fiber reinforced composite parts, because now the vacuum assembly is no longer manually built. The flexibility of the process in terms of construction makes it possible to manufacture according to a reliable process, even vacuum assemblies of different types and geometries, without having to this end, for example, replace large parts of the installation.
    [0008] The individual material layers may for example be a vacuum sheet, a suction fleece, a flow aid, a separator sheet, a tear-off fabric and / or a sealing strip. empty.
    [0009] According to an advantageous embodiment of the process, the pre-assembled vacuum assembly is wound on a roll after its manufacture, so that it is transportable. It is also conceivable that several pre-assembled vacuum assemblies are manufactured successively and wound together on a roll.
    [0010] In accordance with one advantageous embodiment of the method, at least two layers of material mounted together are attached locally by means of an adhesive. For this purpose, with the aid of a gluing device, an adhesive 3028448 6 is applied to one or both layers of material, then the two layers of material are assembled on the side where the glue has been applied, so that the two layers of material can be attached locally by means of the glue. The gluing unit, for example in the form of glue nozzles, can apply the desired amount of glue to the layers of material. But it is also conceivable to apply with the sizing device a kind of double-sided adhesive tape on one of the layers of material, so that when mounting the two layers of material with each other, those these are attached locally to each other because of the double-sided adhesive tape. According to an advantageous embodiment, after mounting the layers of material, one or more plies of material are produced by means of a lay-up device, by applying against one another two sections of 15 layers of material, which form the future fold of material. The production of a fold of material in the mounted material layers makes it possible to confer three-dimensional structures on the pre-assembled vacuum assembly, which will subsequently correspond to the part geometry to be produced. By means of a position measuring device, it is possible to detect the position and the orientation of the vacuum assembly, in order to then be able to realize in the vacuum assembly, in the necessary position, the fold of material, depending on the part data. For this purpose, two sections of material layers are grouped against each other, so that at least the layer of lower material within this section of material layer is in contact with itself. . The ply of material may for example be produced by a kind of vacuum-assisted stamping. Such plies of material are, for example, required in a vacuum assembly, for example for reinforcing elements such as stiffeners or slats, which protrude cantilevered from the surface of the reinforced composite part. fiber to manufacture. It is particularly advantageous here for the bundles of bundled material layers to be welded to each other at the edges by a welding device which can be an integral part of the wrapping device. As a general rule, the last layer of material is a vacuum sheet, it is particularly advantageous that the welding device is designed for welding sheets or films, for example by supplying thermal energy, so that the upper material layer (vacuum sheet) at the edges of the material fold is welded reciprocally by sheet-by-sheet welding. For this purpose, the welding device comprises two movable branches relative to one another, the two sections of material layers being introduced between the two branches, which are then brought closer to each other, in 10 pressing the two sections of material layers of the vacuum assembly together and welding them to each other. According to an advantageous embodiment, the geometry of the prefabricated evacuation assembly, manufactured, is taken up by means of a geometry survey device, for example a geometry-based surveying device. camera, and compared by means of a calculation unit to a set geometry to check the accuracy of the geometry. It is thus possible to verify, during a downstream quality assurance process, whether the pre-assembled automated vacuum assembly meets the tolerances imposed on the part. The desired object is also achieved by a process for manufacturing a fiber reinforced composite part, which is made by curing a matrix material infused into a fiber material using a jacking assembly. vacuum, comprising the following steps: a) supply and preparation of a prefabricated evacuation assembly, manufactured according to the process according to the invention mentioned above, for the automated manufacture of a vacuum assembly, vacuum-tight sealing of a fiber-based material having been introduced into a forming tool, by means of the pre-assembled vacuum assembly, and c) manufacturing of the fiber-reinforced composite part by curing the infused matrix material in the fiber material. It is thus proposed to begin by supplying and preparing a pre-assembled vacuum assembly, having been manufactured in accordance with the above-mentioned method. Then, using the pre-assembled vacuum assembly, a fiber-based material introduced into a forming tool is sealed in a vacuum-tight manner and the fiber-reinforced composite part is manufactured.
    [0011] The object of the invention is also achieved by means of an installation for automatically manufacturing a vacuum assembly for the manufacture of a fiber-reinforced composite part, this fiber-reinforced composite part. being made by curing a matrix material infused into a fiber-based material, using a vacuum assembly. The installation comprises: a material supply and preparation device for the preparation and supply of several layers of unassembled material for the vacuum assembly; a mounting device adapted to co-mount, layer by layer, layers of material which are supplied by the material supply and preparation device to the mounting device, to form a pre-assembled vacuum assembly; and a cutting device, configured to fabricate the material layers according to prescribed geometrical data, before, during, or after mounting the material layers. The installation is in particular configured for the implementation of the aforementioned method for manufacturing a vacuum assembly.
    [0012] The installation comprises a material supply and preparation device for the preparation and supply of several layers of unassembled material for the vacuum assembly, as well as a mounting device designed to mount a layer together by layer, material layers fed to the mounting device by the material supply and preparation device to form a pre-made vacuum assembly. By means of a cutting device, which is part of the installation, the layers of material are made according to prescribed geometrical data, before, during or after the mounting of the layers of material, for example by cutting them according to a prescribed geometry. According to advantageous embodiments: the material supply and preparation device is configured to prepare and supply the web-like material layers on the rolls; - a winding device is configured to wind the pre-assembled vacuum assembly having been manufactured; The mounting device has a sizing unit, configured to apply an adhesive to at least one layer of material to locally fix two material layers mounted together; the mounting device comprises one or more return rollers for mounting the layers of material together, the cutting device being configured to make the layers of material on at least one of the return rollers; - there is provided a draping device, configured to make a fold of material in the material layers mounted together, two sections 10 of layers of material, which will form the future fold of material, being applied against each other by the draping device; the draper comprises a welding device configured to weld together, at the edges, the sections of material layers folded against each other, the welding device comprising two diametrically opposed legs and mounted movably one relative to each other, between which can be inserted diametrically opposite the two sections of material layers, so that by approximation of the legs the sections of material layers are compressed and welded to one another at the edges; There is provided a geometry survey device, which is configured to record the geometry of the pre-assembled, manufactured vacuum assembly, which is connected to a computing unit designed to verify the accuracy of the geometry by comparing the raised geometry with a set geometry.
    [0013] Thus, the mounting device may comprise, for example, one or more return rollers for mounting the layers of material together, the installation being configured so that the layers of material are fed to a return roller by the delivery device and of material preparation, the material layers being then assembled by the return roller. This may for example be cascaded, with several return rollers respectively joining two or more layers of different material, and these several layers of material thus assembled are then mounted together to form a vacuum assembly. The cutting device can here be configured to cut directly on the return rollers, allowing the most compact installation possible and with the least possible footprint. The prescribed geometrical data may for example be determined according to geometrical data of the forming tool and / or the workpiece to be produced. The invention will be further explained, by way of example, with reference to the accompanying drawings. These show: FIG. 1 representation of the process chain for the automated manufacture of the vacuum assembly; Figure 2 schematic representation of an installation for the automated manufacture of a vacuum assembly; Figure 3 Schematic representation of the manufacture of a fold. Figure 1 shows the entire process chain for automated manufacturing of a vacuum assembly. In a first step, the digital geometrical data 10 is provided and prepared for the manufacture of the vacuum assembly, the digital geometrical data including in particular the preparation of the different individual material layers. The digital geometrical data can for example be produced from part data 11, forming tool data 12 and / or from properties of the vacuum assembly 13 to be manufactured, itself. . During the second step, the preparation and supply of materials 20 is made available, providing the layers of material necessary for the vacuum assembly, in particular in the form of a strip.
    [0014] In the next step 30, the individual material layers are mounted together in packets, so that several packets of material layers 31, 32 and 33 each comprising different layers of material each result. This is for example necessary when different layers of material require different confections. The packages of layers of material 31, 32 and 33 respectively different are then made by means of the cutting device, in a fourth step 40, so that a result of a first package 40 made 41, a second prepared packet 42 and a third manufactured package 43. As a result, the pre-assembled packages 41, 42, 43 are mounted together in a global package during a global assembly operation, so that one thus has, at least in dimensions, manufactured a pre-made vacuum assembly. The vacuum assembly thus pre-assembled, namely the individual material layers mounted together, is then, if necessary, brought to a draping device, so as to be able to produce in the overall package folds of material, when In another step 60. In making the pleats in step 60, the plies of material are welded at the botds, particularly by sheet welding, so that the vacuum assembly is also closed. in a vacuum-tight manner at the edges of the folds of material.
    [0015] In another optional process step 70, for example, a sealing strip can be applied to complete the pre-assembled vacuum assembly. Then, in the last step 80, the prefabricated vacuum assembly, the manufacture of which is complete, is wound or wound so that it is, for example, transportable. Figure 2 schematically shows an exemplary embodiment of an installation 100 for automated manufacturing of a vacuum assembly for the manufacture of fiber reinforced composite parts. The embodiment of Figure 2 is analogous to consider as an example concerning the choice of materials. The installation 100 firstly comprises a device for supplying and preparing materials 110 making it possible to supply and prepare the different layers of material M1 to M4. For this purpose, the material supply and preparation device 110 comprises, for each layer of material M1 to M4, a roll of material 111, 112, 113 and 114 with which the layer of material is provided and prepared. M1 to M4 respectively.
    [0016] The layer of material M1, supplied and prepared by the material roll 111, may for example be the vacuum sheet, while the layer of material M2, which is supplied and prepared by the material roll 112, is a non-woven suction. The material layer M3 may for example be a separating sheet, while the layer of material M4 for example provides a tear-off fabric.
    [0017] The unmounted layers of material M1 to M4 are now fed to a mounting device 120, wherein the layers of material are mounted together in packs, respectively, using pairs of rolls 121 and 122. Thus, in In the embodiment of FIG. 2, the layers of material M1 and M2 are mounted together via a first pair of rollers 121, so that a package of layers of M12 material results, while that the layers of material M3 and M4 are mounted together in a package of layers of material M23 by means of a second pair of rollers 122.
    [0018] The package of layers of material M12 thus consists of a vacuum sheet and a suction nonwoven in assembled form, while the package of layers of material M23 comprises the separation sheet as well as a tear-off fabric.
    [0019] The mounting device may further comprise a sizing device 130 which applies an adhesive on at least one side of a material layer, in this case the layer of material M1, so that the layer of material M1 can be locally attached to the layer of material M2.
    [0020] By means of a third pair of rollers 123, the bundles of layers of material M12 and M23 are then mounted together, so that a total bundle of the material layers is formed into a bundle assembly. under vacuum not made. Then, this bundle of layers of fully bundled material is fed to a 14th tonal cutter for making on a return roll 141 the layer of material material consisting of the four layers of material M1 to M4. It is also conceivable to arrange the cutter 140 on each pair of rollers 121 or 122, or before said pairs of rolls, so as to suitably make each layer of material M1 to M4 prior to assembly. It is also conceivable to arrange the cutting device 140 after the first and the second pair of rollers 121, 122, but before the third pair of rollers 123, so as to individually make the packages of individual material layers M1 / 2 and M2 / 3. This is important when the auxiliary materials or the individual material layers M1 to M4 must have different sizes. Following the cutting device 140 of the installation 100, there is the draping device 150, making it possible to produce folds of material in the vacuum assembly now pre-assembled, the folds of material being welded. at the edges. The mode of operation of the welding device 155 will be explained in more detail with reference to FIG. 3. The draping device 150 may, in one embodiment, for example be configured so that grooves are provided in which is drawn or pressing the package of layers of material, thereby deforming the package of layers of material out of its extent plane. This can for example be done in the manner of a vacuum-assisted stamping process. But it is also conceivable to provide deflection elements which deform the layers of material so that a fold of material is formed where the two sections of layers 20 of material are applied against each other. After making possible folds of material by the draper device 150, the vacuum assembly thus manufactured in an automated manner is finally wound on a roll 160 and being thus transportable.
    [0021] In addition, it is conceivable that another layer of material is a vacuum sealing strip, which is applied to the edges of the pre-assembled vacuum assembly, preferably on the setting sheet. under vacuum. This makes possible an automatic application of the vacuum seal tape. This advantageously takes place between the draper device 150 and the winding device 160. This is shown schematically by a material layer supply system 115, which introduces a vacuum sealing strip as a layer of M5 material. .
    [0022] The integration of leak detection, online, for the folds that have been made, is also possible. Verification of geometric accuracy can be performed by an online geometry survey system, for example using different camera systems not shown. The glue 3028448 14 applied by the sizing device 130 may for example be applied by one or more nozzles, the hardening of the glue may be assisted by an infrared unit.
    [0023] In addition, at the beginning of the draping step, it is possible to perform an online survey or detection of the position, for example by laser optical cutting sensors or CCD camera systems, to thereby ensure automated adjustment of the draping device 150.
    [0024] Figure 3 schematically shows the welding device 155 for welding the fold of material in its edge region. For this purpose, the welding device 155 comprises two branches 151 and 152 movably mounted relative to each other and arranged diametrically opposite. In the space between the two branches 151 and 152 is then inserted the fold of material with the two sections of material layer A and B, as shown on the left side of Figure 3. Then, the two branches 151 and 152 are brought closer to each other, thereby pressing the two sections of material layer A and B against one another. This is shown on the right side of FIG. 3. The two sections of material layer A and B thus form a fold of grouped material. The welding device 155 comprises a thermal energy unit 153, 25 which is activated when the two sections of material layer A and B are pressed against each other, so as to introduce thermal energy into the zone. edge of the fold of material. This leads to the welding of the edge region of the fold of material, so that the entire fold of material is sealed in a vacuum-tight manner (except the area where the projecting element is to be introduced into the fold of material) .
