Description

Verfahren zum Verbinden eines Metall-Polymer-Laminats Technisches Gebiet  Method of joining a metal-polymer laminate Technical field
Die Erfindung betrifft ein Verfahren zum Verbinden eines Metall-Polymer-Laminats, welches mindestens eine metallische Schicht mit einer stoffschlüssig angebundenen Schicht aus einem Polymer umfasst, mit mindestens einem Verbindungspartner.  The invention relates to a method for joining a metal-polymer laminate, which comprises at least one metallic layer with a cohesively bonded layer of a polymer, with at least one bonding partner.
Technischer Hintergrund Technical background
Ein Verfahren zum Stumpfschweißen von Verbundplatten ist zum Beispiel aus der DE 1 955 970 A bekannt. In der DE 10 2011 121 899 AI wird ein Verfahren zur Herstellung von Schalenstrukturen beschrieben. Die EP 1 306 292 Bl betrifft die Herstellung eines Trägerbauteils, bei dem ein Grundkörper aus einem Sandwich - Werkstoff aufgebaut ist.  A method of butt welding composite panels is known, for example, from DE 1 955 970 A. DE 10 2011 121 899 A1 describes a process for producing shell structures. EP 1 306 292 B1 relates to the production of a carrier component in which a basic body is constructed from a sandwich material.
Aus dem Stand der Technik sind Werkstoffverbunde, insbesondere Hybridwerkstoffe mit mindestens einer metallischen Lage und mindestens einer Lage aus einem Polymer zum Herstellen eines Bauteils bekannt. Aus der deutschen Offenlegungsschrift DE 21 66 791 AI geht hervor, wie aus einem flachen Hybridwerkstoff ein Rohr erzeugt werden kann. Dabei umfasst der Hybridwerkstoff eine metallische Lage, eine Polymerlage die vollflächig mit der metallischen Lage verbunden ist, und eine weitere Lage aus einem Polymer, die durch das Formen des flachen Hybridwerkstoffs zu einem Rohr als Verbindungsmittel zum Schließen des Rohres vorgesehen ist. In der DE 10 2013 109 616 AI ist ein Halbzeug beschrieben, welches eine metallische Trägerschicht und eine mit dieser stoffschlüssig angebundenen Polymerschicht aufweist. Die Polymerschicht dient als Koppelschicht zum Verbinden von insbesondere angespritzten Verbindungspartnern aus Polymer auf der der metallischen Schicht abgewandten Seite. Ein Verbinden des Verbindungspartners mit dem Halbzeug ist daher nur von einer Seite, nämlich auf der Koppelschicht-Seite möglich. Material composites, in particular hybrid materials with at least one metallic layer and at least one layer of a polymer for producing a component are known from the prior art. German Laid-Open Application DE 21 66 791 A1 discloses how a tube can be produced from a flat hybrid material. In this case, the hybrid material comprises a metallic layer, a polymer layer which is fully connected to the metallic layer, and a further layer of a polymer, which is provided by the molding of the flat hybrid material to a tube as a connecting means for closing the tube. DE 10 2013 109 616 A1 describes a semifinished product which has a metallic carrier layer and a polymer layer that is adhesively bonded to it. The polymer layer serves as a coupling layer for connecting, in particular, molded-on connection partners made of polymer on the side facing away from the metallic layer. A connection of the connection partner with the semifinished product is therefore possible only from one side, namely on the coupling layer side.

Als Fasern sind insbesondere Karbonfasern, Glasfasern, Naturfasern, Aramidfasern, Polymerfasern, Metallfasern, Keramikfasern, mineralische Fasern, recycelte Fasern oder deren Mischungen verwendbar. Hierbei ist ferner der Einsatz als Kurzfaser, Langfaser und/oder als Endlosfaser vorstellbar. Insbesondere können die Fasern als Roving, Matte, Gewebe, Vlies, Tape und/oder Gelege bereitgestellt werden. Bei einer mehrlagigen faserverstärkten Ausführung kann auch mindestens eine der Lagen faserfrei ausgeführt sein. The layer of a polymer can be made in one or more layers.

As the material for the polymer matrix, in particular, the aforementioned polymers are usable. In particular, carbon fibers, glass fibers, natural fibers, aramid fibers, polymer fibers, metal fibers, ceramic fibers, mineral fibers, recycled fibers or mixtures thereof can be used as the fibers. Here, the use as short fiber, long fiber and / or endless fiber is also conceivable. In particular, the fibers can be used as roving, mat, fabric, fleece, Tape and / or scrim be provided.

Zur Bildung respektive Bereitstellung des Metall-Polymer-Laminats sind die metallische Schicht und die Schicht aus Polymer stoffschlüssig miteinander verbunden. Zur Erhöhung der Haftung zwischen den beiden Schichten kann auch eine Zwischenschicht in Form eines Haftvermittlers zwischen Metall und Polymer berücksichtigt werden. Das Metall-Polymer- Laminat, welches zur Verbindung mit mindestens einem Verbindungspartner bereitgestellt wird, kann eben oder bereits geformt, insbesondere endgeformt ausgebildet sein. Das Metall- Polymer-Laminat weist beispielsweise eine metallische Schicht mit einer Dicke zwischen 0, 1 und 1,0 mm und eine Schicht aus Polymer mit einer Dicke zwischen 0,2 und 3,0 mm auf. To form respectively provide the metal-polymer laminate, the metallic layer and the layer of polymer are firmly bonded together. To increase the adhesion between the two layers, an intermediate layer in the form of an adhesion promoter between metal and polymer can also be taken into account. The metal-polymer laminate which is provided for connection to at least one bonding partner may be flat or already formed, in particular end-formed. The metal-polymer laminate has, for example, a metallic layer with a thickness between 0, 1 and 1.0 mm and a layer of polymer with a thickness between 0.2 and 3.0 mm.
Gemäß einer bevorzugten Ausführung umfasst das Metall-Polymer-Laminat mindestens eine weitere metallische Schicht und/oder eine weitere Schicht aus einem Polymer, die stoffschlüssig angebunden ist. Vorzugsweise ist das Metall-Polymer-Laminat als Sandwichmaterial mit zwei metallischen Schichten, die als Decklagen fungieren und eine zwischen den metallischen Schichten angeordnete Schicht aus einem Polymer, welche als Kernschicht fungiert, ausgeführt. Dadurch kann in vorteilhafter Weise ein Verbinden eines Metall-Polymer- Laminats auf der metallischen Seite über eine freie Oberfläche respektive freie Oberflächen einseitig oder beidseitig am Metall-Polymer-Laminat mit einem Verbindungspartner erfolgen. According to a preferred embodiment, the metal-polymer laminate comprises at least one further metallic layer and / or a further layer of a polymer, which is materially bonded. Preferably, the metal-polymer laminate is designed as a sandwich material with two metallic layers acting as cover layers and a layer arranged between the metallic layers of a polymer which acts as a core layer. This can advantageously be done on one side or on both sides of the metal-polymer laminate with a connection partner joining a metal-polymer laminate on the metallic side of a free surface or free surfaces.
Gemäß einer bevorzugten Ausführung ist der mindestens eine Verbindungspartner aus einem Polymer oder einem niedrig schmelzenden metallischen Material gebildet.

Beispielsweise ist das Polymer des Verbindungspartners artgleich wie das Polymer der Schicht des Metall-Polymer-Laminats, welches beispielsweise in seinem Anbindungsbereich und/oder die freie Oberfläche am Metall-Polymer- Laminat insbesondere durch Erwärmen vor dem Verbinden einen Stoffschluss begünstigt. Das Polymer kann als Formmasse, Spritzmasse, SMC (sheet molding Compound), BMC (bulk molding Compound) oder insbesondere faserverstärktes Organoblech bereitgestellt werden.

Als niedrig schmelzendes metallisches Material kommen beispielsweise die Metalle in Frage, deren Schmelztemperatur nicht höher als 300°C, insbesondere nicht höher als 270 °C, vorzugsweise nicht höher als 230°C ist, sodass das Metall-Polymer-Laminat nicht zu hohen Temperaturen während des Verbindens ausgesetzt wird, welche sich nachteilig, insbesondere auf die Schicht aus Polymer auswirken können. According to a preferred embodiment, the at least one connection partner is formed from a polymer or a low-melting metallic material.

Beschreibung der bevorzugten Ausführungsform Description of the preferred embodiment
In Fig. 1 ist ein schematischer Schnitt durch eine erste Ausgestaltung vor dem Verbinden eines Metall-Polymer-Laminats (1) mit einem Verbindungspartner (2) dargestellt. Das Metall- Polymer-Laminat (1) ist als Sandwich ausgebildet und umfasst zwei metallische SchichtenIn Fig. 1 is a schematic section through a first embodiment before connecting a metal-polymer laminate (1) with a connection partner (2) is shown. The metal- Polymer laminate (1) is sandwiched and comprises two metallic layers
(1.1) , die als Deckbleche fungieren, vorzugsweise Stahlbleche mit einer Dicke zwischen 0, 1 bis 1,0 mm, und eine zwischen den beiden Schichten (1.1) angeordnete Schicht aus Polymer(1.1), which act as cover plates, preferably steel sheets with a thickness between 0, 1 to 1.0 mm, and between the two layers (1.1) arranged layer of polymer
(1.2) , welche als Kernschicht mit einer Dicke zwischen 0,2 bis 3,0 mm fungiert, beispielsweise aus mehreren Lagen (1.21) bestehen kann und beispielsweise aus einer thermoplastischen Matrix, vorzugsweise einem Blend aus PA-PE oder PA, PE, PPS, PSU, PP, PU, mit einem Fasermaterial beispielsweise aus Karbon, Aramid und/oder Glas gebildet ist. Die im Schnitt dargestellte obere metallische Schicht (1.1) ist zumindest bereichsweise, insbesondere im Randbereich im Vergleich zur Schicht aus Polymer (1.2) kleiner dimensioniert, so dass auf der oberen Seite des Metall-Polymer-Laminats (1) zumindest bereichsweise eine freie Oberfläche (1.22) der Schicht aus Polymer (1.2) zum Verbinden mit dem Verbindungspartner (2) bereitgestellt wird. Zur Erzeugung der kleineren Dimensionierung im Vergleich zu der Schicht aus Polymer (1.2) wird die obere metallische Schicht (1.1) zumindest bereichsweise am Metall- Polymer-Laminat (1) entfernt, beispielsweise mechanisch oder thermisch. Alternativ kann die kleinere Dimensionierung der oberen metallischen Schicht (1.1) bereits im Zuge der Herstellung des Metall-Polymer-Laminats (1) entsprechend berücksichtigt werden. Als Verbindungspartner (2) wird beispielsweise ein Organoblech bestehend aus einem gleichen oder ähnlichen Matrixmaterial wie das Polymer des Metall-Polymer-Laminats oder ein weiteres Metall-Polymer-Laminat bereitgestellt. Vor dem Verbinden kann die freie Oberfläche (1.22) der Schicht aus Polymer (1.2) thermisch, chemisch und/oder mechanisch aktiviert werden. Zur Begünstigung des Stoffschlusses kann zumindest die freie Oberfläche (1.22) der Schicht des Polymers (1.2) vor dem Verbinden erwärmt werden. Der Verbindungspartner (2) wird zumindest an der freien Oberfläche (1.22) der Schicht aus Polymer (1.2) zum Verbinden mit dem Metall-Polymer-Laminat (1) mittels eines Pressverfahrens angepresst. (1.2), which acts as a core layer with a thickness between 0.2 to 3.0 mm, for example, of several layers (1.21) may consist and for example of a thermoplastic matrix, preferably a blend of PA-PE or PA, PE, PPS , PSU, PP, PU, is formed with a fiber material, for example made of carbon, aramid and / or glass. The upper metallic layer (1.1), which is shown in section, is dimensioned smaller, at least in some areas, in comparison to the layer of polymer (1.2) so that a free surface (at least in regions) is formed on the upper side of the metal-polymer laminate (1). 1.22) of the layer of polymer (1.2) is provided for connection to the connection partner (2). To produce the smaller dimensions in comparison to the layer of polymer (1.2), the upper metallic layer (1.1) is at least partially removed on the metal-polymer laminate (1), for example mechanically or thermally. Alternatively, the smaller dimensioning of the upper metallic layer (1.1) can already be taken into account in the course of the production of the metal-polymer laminate (1). As connection partner (2), for example, an organic sheet consisting of a same or similar matrix material as the polymer of the metal-polymer laminate or another metal-polymer laminate is provided. Before joining, the free surface (1.22) of the layer of polymer (1.2) can be activated thermally, chemically and / or mechanically. To promote the adhesion, at least the free surface (1.22) of the layer of the polymer (1.2) can be heated prior to bonding. The bonding partner (2) is pressed on at least on the free surface (1.22) of the layer of polymer (1.2) for bonding to the metal-polymer laminate (1) by means of a pressing process.
In Fig. 2 ist ein schematischer Schnitt durch eine zweite Ausgestaltung vor dem Verbinden eines Metall-Polymer-Laminats (1) mit einem Verbindungspartner dargestellt. Im Unterschied zu der Ausführung in Fig. 1 weist das Metall-Polymer-Laminat (1) eine Ausnehmung (1.3) in der oberen metallischen Schicht (1.1) am Metall-Polymer-Laminat (1) auf, durch die eine freie Oberfläche (1.22) der Schicht aus Polymer (1.2) zum Verbinden mit einem Verbindungspartner bereitgestellt wird. Die Einbringung der mindestens einen Ausnehmung (1.3) in der oberen metallischen Schicht (1.1) am Metall-Polymer-Laminat (1.1) kann bedarfsgerecht erfolgen und wird beispielsweise mechanisch oder thermisch durchgeführt. Mittels Pfeil symbolisiert kann beispielsweise ein nicht dargestellter Verbindungpartner, vorzugsweise ein faserverstärktes Polymer durch Spritzgießen an der freien Oberfläche (1.22) der Schicht aus Polymer (1.2) angespritzt werden und dadurch mit dem Metall-Polymer-Laminat (1) verbunden werden. In Fig. 2 is a schematic section through a second embodiment before connecting a metal-polymer laminate (1) is shown with a connection partner. In contrast to the embodiment in FIG. 1, the metal-polymer laminate (1) has a recess (1.3) in the upper metallic layer (1.1) on the metal-polymer laminate (1), through which a free surface (1.22 ) of the layer of polymer (1.2) is provided for connection to a bonding partner. The introduction of the at least one recess (1.3) in the upper metallic layer (1.1) on the metal-polymer laminate (1.1) can be done as required and is carried out, for example, mechanically or thermally. For example, an unillustrated bonding partner, preferably a fiber-reinforced polymer, can be symbolized by means of an arrow by injection molding on the free surface (1.22) of the layer Polymer (1.2) are sprayed and thereby connected to the metal-polymer laminate (1).
In Fig. 3 ist ein schematischer Schnitt durch eine dritte Ausgestaltung nach dem Verbinden eines Metall-Polymer-Laminats (1) mit einem Verbindungspartner (2) dargestellt. Die obere und untere metallische Schicht (1.1) sind im Vergleich zur Schicht aus Polymer (1.2) kleiner dimensioniert, so dass im Randbereich beidseitig freie Oberflächen (1.22) am Metall-Polymer- Laminat (1) zum Verbinden bereitgestellt wurden. Die Schicht aus Polymer (1.2) wurde im Bereich der freien Oberflächen (1.22) vor dem Verbinden umgeformt und/oder angeformt, indem die Schicht aus Polymer (1.2) im Bereich der freien Oberflächen (1.22) aus der Metall- Polymer-Laminat-Ebene geformt wurde. Die Schicht des Polymers (1.2) wurde in ihrer Erstreckung geteilt und zu einer Art Schwalbenschanz (1.4) vor dem Verbinden geformt. Die Fasern im faserverstärkten Polymer sind im Bereich der freien Oberflächen (1.22) belastungsgerecht angeordnet. Der Schwalbenschanz (1.4) im Bereich der freien Oberflächen (1.22) bewirkt neben einem Stoffschluss mit dem Verbindungspartner (2) auch einen Formschluss und somit eine belastbarere Verbindung zwischen Metall-Polymer-Laminat (1) und Verbindungspartner (2). Der Verbindungpartner (2) besteht vorzugsweise aus einem faserverstärkten Polymer und wurde durch Spritzgießen an der freien Oberfläche (1.22) der Schicht aus Polymer (1.2) angespritzt. Alternativ kann der Verbindungpartner auch aus einem unverstärkten thermoplastischen oder duroplastischen Polymer bestehen und durch Formpressen an der freien Oberfläche der Schicht aus Polymer angepresst werden. In Fig. 3 is a schematic section through a third embodiment after joining a metal-polymer laminate (1) with a connection partner (2) is shown. The upper and lower metallic layer (1.1) are smaller in size compared to the layer of polymer (1.2), so that free surfaces (1.22) on the metal-polymer laminate (1) were provided for bonding in the edge region on both sides. The layer of polymer (1.2) was reformed and / or molded in the region of the free surfaces (1.22) before joining by exposing the layer of polymer (1.2) in the region of the free surfaces (1.22) of the metal-polymer laminate plane was formed. The layer of the polymer (1.2) was divided in its extension and formed into a kind of dovetail (1.4) before joining. The fibers in the fiber-reinforced polymer are arranged in the area of the free surfaces (1.22). The Schwalbenschanz (1.4) in the area of the free surfaces (1.22) in addition to a material connection with the connection partner (2) also a positive connection and thus a stronger connection between metal-polymer laminate (1) and connection partner (2). The bonding partner (2) preferably consists of a fiber-reinforced polymer and was injection-molded onto the free surface (1.22) of the layer of polymer (1.2). Alternatively, the bonding partner can also consist of an unreinforced thermoplastic or thermosetting polymer and be pressed by compression molding on the free surface of the layer of polymer.
In Fig. 4 ist ein schematischer Schnitt durch eine vierte Ausgestaltung nach dem Verbinden zweier Metall-Polymer-Laminate (1) mit einem Verbindungspartner (2) dargestellt. Der Verbindungspartner (2) dient zum einen zum Verbinden zweier Metall-Polymer-Laminate (1) und kann zum anderen auch noch weitere Funktionen übernehmen. Die oberen und unteren metallischen Schichten (1.1) sind im Vergleich zu den Schichten aus Polymer (1.2) kleiner dimensioniert, so dass die Metall-Polymer-Laminate (1) im Randbereich jeweils beidseitig freie Oberflächen (1.22) aufweisen. Der Verbindungspartner (2) ist nicht nur stoffschlüssig mit den beiden Metall-Polymer-Laminaten (1) an den freien Oberflächen (1.22) verbunden, sondern deckt auch die Kanten der metallischen Schichten (1.1) im Bereich der freien Oberflächen (1.22) der Metall-Polymer-Laminate (1) ab bzw. umgibt diese, um die offenen Kanten der metallischen Schichten (1.1) zu schützen. Der Verbindungpartner (2) besteht vorzugsweise aus einem faserverstärkten Polymer und wurde durch Spritzgießen an den freien Oberflächen (1.22) der Schichten aus Polymer (1.2) angespritzt. Alternativ kann der Verbindungpartner auch aus einem unverstärkten thermoplastischen oder duroplastischen Polymer bestehen und durch Formpressen an der freien Oberfläche der Schicht aus Polymer angepresst werden. FIG. 4 shows a schematic section through a fourth embodiment after connecting two metal-polymer laminates (1) to a connection partner (2). The connection partner (2) serves on the one hand for connecting two metal-polymer laminates (1) and on the other hand can also assume other functions. The upper and lower metallic layers (1.1) are smaller in size compared to the layers of polymer (1.2), so that the metal-polymer laminates (1) in the edge region in each case on both sides free surfaces (1.22). The connection partner (2) is not only materially bonded to the two metal-polymer laminates (1) on the free surfaces (1.22), but also covers the edges of the metallic layers (1.1) in the region of the free surfaces (1.22) of the metal Polymer laminates (1) from or surrounds these to protect the open edges of the metallic layers (1.1). The bonding partner (2) preferably consists of a fiber-reinforced polymer and was injection-molded onto the free surfaces (1.22) of the layers of polymer (1.2). Alternatively, the connection partner also consist of an unreinforced thermoplastic or thermosetting polymer and are pressed by compression molding on the free surface of the layer of polymer.

Insbesondere können auch noch weitere Schichten aus Polymer und metallischen Schichten vorgesehen werden. Auch andere Materialien hinsichtlich Fasern und Matrix sind verwendbar. Des Weiteren können die Bleche, wenn sie aus einer Stahllegierung bestehen, mit einem Korrosionsschutzüberzug, vorzugsweise auf Zink-Basis, beschichtet sein. Insbesondere zur Erhöhung der Haftung zwischen der metallischen Schicht und der Schicht aus Polymer kann das Blech zumindest einseitig auf der der Schicht zugewandten Seite mit einem Haftvermittler beschichtet sein. The invention is not limited to the embodiments shown in the drawing, in particular the number of layers and / or joining partners is not limited to three. In particular, even further layers of polymer and metallic layers can be provided. Other materials in terms of fibers and matrix are useful. Furthermore, if the sheets are made of a steel alloy, they may be coated with a corrosion protection coating, preferably zinc-based. In particular, in order to increase the adhesion between the metallic layer and the layer of polymer, the sheet may be coated on at least one side on the side facing the layer with an adhesion promoter.
