Description

Die Erfindung betrifft ein Verfahren zum Herstellen eines Hybridbauteils sowie das entsprechend hergestellte Hybridbauteil.The invention relates to a method for producing a hybrid component and the hybrid component produced accordingly.

In zunehmendem Maße finden sogenannte Hybridbauteile, also Bauteile in Mischbauweise Anwendung, bestehend aus Komponenten unterschiedlicher Materialien, um deren jeweiligen materialspezifischen Vorteile miteinander in einem Bauteil zu kombinieren. Im Fahrzeugbau werden daher häufig Faserverbundkomponenten mit metallischen Komponenten kombiniert, um beispielsweise eine erhöhte Festigkeit oder eine verbesserte Anbindungsmöglichkeit an weitere Bauteile oder Fahrzeugstrukturen zu schaffen.Increasingly find so-called hybrid components, ie components in mixed construction application, consisting of components of different materials to combine their respective material-specific advantages together in one component. In vehicle construction, fiber composite components are therefore often combined with metallic components in order, for example, to provide increased strength or an improved connection possibility to other components or vehicle structures.

Eine Verbindung beider Komponenten zu einem gemeinsamen Bauteil erfolgt üblicherweise durch Kleben oder mit Hilfe von Verbindungsmitteln, wie Nieten oder Schrauben. Beide Vorgehensweisen sind technisch und wirtschaftlich aufwendig. So müssen zur Vorbereitung einer Klebeverbindung die Klebeflächen zunächst umfassend gereinigt und oftmals aufgeraut werden, ohne dabei die Faserstruktur zu beschädigen. Werden zur Verbindung dagegen Verbindungsmittel eingesetzt, so sind üblicherweise präzise platzierte Löcher in den Bauteilen erforderlich, die meist nachträglich eingebracht werden und somit in ungünstigen Fällen die Faserstruktur beeinträchtigen können.A connection of both components to a common component is usually carried out by gluing or by means of connecting means, such as rivets or screws. Both approaches are technically and economically complex. Thus, in order to prepare an adhesive bond, the adhesive surfaces must first be comprehensively cleaned and often roughened without damaging the fiber structure. If, on the other hand, connecting means are used for the connection, then precisely placed holes in the components are usually required, which are usually introduced later and thus can impair the fiber structure in unfavorable cases.

Eine Aufgabe der Erfindung ist es daher, ein Verfahren zum Herstellen eines Hybridbauteils bereitzustellen, welches die genannten Nachteile zumindest reduziert oder sogar beseitigt.An object of the invention is therefore to provide a method for producing a hybrid component, which at least reduces or even eliminates the disadvantages mentioned.

Diese Aufgabe wird gelöst durch ein Verfahren zur Herstellung eines Hybridbauteils gemäß Patentanspruch 1 sowie einem Hybridbauteil mit den Merkmalen des Patentanspruchs 13. Vorteilhafte Ausführungsformen ergeben sich aus den hiervon abhängigen Patentansprüchen.This object is achieved by a method for producing a hybrid component according to claim 1 and a hybrid component having the features of claim 13. Advantageous embodiments result from the dependent claims therefrom.

Demnach wird ein Verfahren zum Herstellen eines Hybridbauteils mit zumindest den folgenden Schritten vorgestellt:

  1. a. Bereitstellen eines Metallelements mit einem Verbindungsabschnitt, welcher zum Verbinden mit einem Faserhalbzeug ausgebildet ist und mindestens einen plastisch verformbaren Verbindungsfortsatz umfasst,
  2. b. Einbringen des Metallelements und des Faserhalbzeugs in ein geöffnetes Presswerkzeug, wobei der mindestens eine Verbindungsfortsatz in das Faserhalbzeug zumindest hineinragt,
  3. c. Schließen des Presswerkzeugs und Pressen des Metallelements und des Faserhalbzeugs zum Erzeugen des Hybridbauteils, wobei der mindestens eine Verbindungsfortsatz plastisch umgeformt wird, um eine formschlüssige Verbindung des Metallelements mit dem Faserhalbzeug bereitzustellen, und wobei eine Matrix des Faserhalbzeugs zumindest teilweise ausgehärtet wird,
  4. d. Entnehmen des erzeugten Hybridbauteils aus dem Presswerkzeug.
Accordingly, a method for producing a hybrid component is presented with at least the following steps:
  1. a. Providing a metal element with a connecting section, which is designed to connect to a semi-finished fiber product and comprises at least one plastically deformable connecting extension,
  2. b. Introducing the metal element and the semifinished fiber product into an open pressing tool, the at least one connecting extension projecting at least into the semi-finished fiber product,
  3. c. Closing the pressing tool and pressing the metal element and the semi-finished fiber product to produce the hybrid component, wherein the at least one connecting extension is plastically deformed in order to provide a positive connection of the metal element with the semifinished fiber product, and wherein a matrix of the semifinished fiber article is at least partially cured,
  4. d. Removing the generated hybrid component from the pressing tool.

Das auf diese Weise herzustellende Hybridbauteil umfasst also zumindest eine Kombination des Metallelements und des Faserhalbzeugs. Für eine gegenseitige Verbindung weist das Metallelement den Verbindungsabschnitt auf, mit dem das Metallelement mit dem Faserhalbzeug verbunden wird. Der Verbindungsabschnitt kann lediglich ein Teilabschnitt einer Oberfläche des Metallelements sein oder eine vollständige Oberfläche des Metallelements umfassen. Entsprechend kann eine lediglich teilweise Überlappung beider Komponenten, also des Metallelements und des Faserhalbzeugs, erfolgen oder aber ein großflächiger Kontakt hergestellt werden.The hybrid component to be produced in this way thus comprises at least one combination of the metal element and the semi-finished fiber product. For a mutual connection, the metal element has the connecting portion, with which the metal element is connected to the semifinished fiber product. The connecting portion may be only a portion of a surface of the metal member or may include a complete surface of the metal member. Accordingly, only a partial overlap of both components, ie the metal element and the semifinished fiber product, can take place or a large-area contact can be produced.

Zunächst werden hierzu der eine oder die mehreren Verbindungsfortsätze in das Faserhalbzeug eingesteckt, um einen gegenseitigen Eingriff mittels einer Steckverbindung zur gegenseitigen Positionierung der beiden Komponenten zu erzielen. Hierbei kann sich der jeweilige Verbindungsfortsatz durch das Faserhalbzeug hindurch erstrecken und auf einer dem Metallelement abgewandten Rückseite austreten, also dort mit einem freien Ende überstehen. Als freies Ende ist ein dem restlichen Metallelement abgewandtes Ende des jeweiligen Verbindungsfortsatzes zu verstehen. Alternativ kann der jeweilige Verbindungsfortsatz aber auch lediglich teilweise in das Faserhalbzeug hinein erstreckt sein.First, for this purpose, the one or more connecting extensions inserted into the semi-finished fiber to achieve mutual engagement by means of a connector for mutual positioning of the two components. In this case, the respective connection extension can extend through the semifinished fiber product and exit on a rear side facing away from the metal element, that is, there with a free end. The free end is to be understood as an end of the respective connection extension facing away from the rest of the metal element. Alternatively, however, the respective connection extension can also only be partially extended into the semi-finished fiber product.

Wie nachfolgend noch im Detail beschrieben wird, ist das Faserhalbzeug in diesem Stadium des Verfahrens noch in einem matrix-freien Zustand oder in einem mit der Matrix vorimprägnierten, jedoch noch nicht ausgehärteten Zustand, so dass das Einstecken des mindestens einen Verbindungsfortsatzes in das Faserhalbzeug problemlos möglich ist.As will be described in detail below, the semi-finished fiber is in this state of the process still in a matrix-free state or in a pre-impregnated with the matrix, but not yet cured state, so that the insertion of the at least one connection extension in the semi-finished fiber easily possible is.

Anschließend wird das Presswerkzeug aus einem geöffneten Zustand in einen geschlossenen Zustand bewegt und hierbei die in das Presswerkzeug eingebrachten Komponenten miteinander verpresst sowie eine Matrix des Faserhalbzeugs zumindest teilweise ausgehärtet. Das auf diese Weise vollständig oder lediglich teilweise ausgehärtete Hybridbauteil kann anschließend aus dem Presswerkzeug entnommen und nachfolgenden Verfahrensschritten zugeführt werden.Subsequently, the pressing tool is moved from an open state to a closed state and in this case the components introduced into the pressing tool are pressed together and at least partially cured a matrix of the semifinished fiber product. The completely or only partially cured hybrid component in this way can subsequently be removed from the pressing tool and fed to subsequent method steps.

Vorzugsweise umfasst das Presswerkzeug ein Unterwerkzeug und ein relativ zu dem Unterwerkzeug in einer Schließrichtung bewegbares Oberwerkzeug, sodass die beiden Werkzeugteile gegeneinander verpressbar sind und gemeinsam im geschlossenen Zustand eine formgebende Kavität für das zu erzeugende Hybridbauteil bilden.Preferably, the pressing tool comprises a lower tool and a relative to the Lower tool in a closing direction movable upper tool, so that the two tool parts are pressed against each other and together form a molding cavity for the hybrid component to be generated in the closed state.

Aufgrund des Schließens und/oder des Pressens erfolgt die plastische Verformung des jeweiligen Verbindungsfortsatzes. Dieser stellt in einem verformten Zustand allein oder zusammen mit anderen verformten Verbindungsfortsätzen (sofern vorhanden) einen Formschluss zwischen dem Metallelement und dem Faserhalbzeug her. Durch das Verformen kann der jeweilige Verbindungsfortsatz zum Beispiel an seinem jeweiligen freien Ende derart umgeformt oder umgebogen werden, dass der Verbindungsfortsatz Fasern des Faserhalbzeuges hintergreift und somit an das Metallelement festklammert. Der Verbindungsfortsatz kann also beispielsweise derart umgeformt werden, dass dieser als Klammer zum lokalen Festklammern des Faserhalbzeugs an dem Metallelement wirkt.Due to the closing and / or pressing, the plastic deformation of the respective connecting extension takes place. In a deformed state, this alone or together with other deformed connection extensions (if present) produces a positive connection between the metal element and the semifinished fiber product. By deforming the respective connection extension, for example, be deformed or bent at its respective free end such that the connection extension engages behind fibers of the semifinished fiber product and thus clamped to the metal element. Thus, the connection extension can for example be reshaped in such a way that it acts as a clamp for local clamping of the semifinished fiber product to the metal element.

Vorzugsweise umfasst das Metallelement hierzu nicht nur einen sondern eine Vielzahl von Verbindungsfortsätzen, die jeweils mit einem ersten Ende mit dem Metallelement verbunden sind und in einem noch nicht umgeformten Zustand mit einem zweiten Ende, dem freien Ende, von einer Oberfläche des Metallelements abstehen.For this purpose, the metal element preferably comprises not only one but a multiplicity of connecting extensions which are each connected at a first end to the metal element and project from a surface of the metal element in a not yet formed state with a second end, the free end.

Gemäß einer Ausführungsform können das Metallelement und das Faserhalbzeug einzeln in das Presswerkzeug eingebracht werden, wobei der mindestens eine Verbindungsfortsatz in das Faserhalbzeug zumindest abschnittsweise eingesteckt wird. Dies bedeutet, dass beide Komponenten erst im Presswerkzeug zusammengesetzt werden. Die Verbindung wird hierbei durch das Einstecken des mindestens einen Verbindungsfortsatzes erzielt, beispielsweise während des Einbringvorgangs in das Presswerkzeug. According to one embodiment, the metal element and the semifinished fiber product can be introduced individually into the pressing tool, wherein the at least one connecting extension is inserted at least in sections into the semi-finished fiber product. This means that both components are first assembled in the pressing tool. The connection is achieved here by the insertion of the at least one connection extension, for example during the Einbringvorgangs in the pressing tool.

Alternativ kann das Metallelement mit dem mindestens einen Verbindungsfortsatz in das Faserhalbzeug zumindest abschnittsweise eingesteckt und anschließend das Metallelement gemeinsam mit dem Faserhalbzeug in das geöffnete Presswerkzeug eingebracht werden. Dies bedeutet, dass beide Komponenten bereits vorab, also vor dem Einbringen in das Presswerkzeug, zusammengesteckt und erst anschließend zusammen als eine gemeinsame Anordnung in das Presswerkzeug eingebracht werden, um gemeinsam verpresst zu werden.Alternatively, the metal element can be at least partially inserted with the at least one connecting extension into the semi-finished fiber product and then the metal element can be introduced into the open pressing tool together with the semifinished fiber product. This means that both components are already put together in advance, that is to say prior to introduction into the pressing tool, and then introduced together as a common arrangement into the pressing tool in order to be pressed together.

In jedem dieser Fälle kann außerdem der Schritt des Pressens ein Pressen des mindestens einen Verbindungsfortsatzes gegen eine in dem Umformwerkzeug ausgebildete, definierte Umformfläche umfassen. Hierbei kann der mindestens eine Verbindungsfortsatz im Wesentlichen quer zu, entgegen und/oder in einer Schließrichtung des Presswerkzeugs umgeformt werden.In each of these cases, the step of pressing may further comprise pressing the at least one connecting extension against a defined forming surface formed in the forming tool. In this case, the at least one connecting extension can be transformed essentially transversely to, counter to and / or in a closing direction of the pressing tool.

Dies bietet die Möglichkeit, dass der mindestens eine Verbindungsfortsatz zum Beispiel derart umgeformt wird, dass dieser jeweils die Fasern des Faserhalbzeugs hintergreift oder zumindest in eine Faserstruktur derart eingreift, dass diese an dem Metallelement festgeklammert wird.This offers the possibility that the at least one connecting extension is, for example, reshaped in such a way that it respectively engages behind the fibers of the semi-finished fiber product or at least engages in a fiber structure in such a way that it is clamped to the metal element.

Zum Beispiel kann die definierte Umformfläche durch eine Ausnehmung im Presswerkzeug gebildet sein, insbesondere durch eine konkave Ausnehmung im Unterwerkzeug oder im Oberwerkzeug. Die Ausnehmung ist vorzugsweise zum Umlenken des mindestens einen Verbindungsfortsatzes ausgebildet. Insbesondere eine konkave Ausgestaltung bietet die Möglichkeit das freie Ende jedes Verbindungsfortsatzes beim Schritt des Schließens und/oder des Pressens umzulenken und so den herzustellenden Formschluss zu erzeugen. Vorzugsweise kann jedem Verbindungsfortsatz eine eigene Ausnehmung in dem Presswerkzeug zugeordnet sein.For example, the defined forming surface may be formed by a recess in the pressing tool, in particular by a concave recess in the lower tool or in the upper tool. The recess is preferably designed for deflecting the at least one connecting extension. In particular, a concave configuration offers the possibility of redirecting the free end of each connection extension during the step of closing and / or pressing and thus to produce the form fit to be produced. Preferably, each connection extension can be assigned its own recess in the pressing tool.

Das Verfahren ist grundsätzlich als Prepreg-Prozess, Resin-Transfer-Moulding-Prozess (kurz: RTM-Prozess) oder als Nasspressprozess ausführbar.The process can basically be carried out as a prepreg process, resin transfer molding process (abbreviated RTM process) or as a wet pressing process.

So kann das Faserhalbzeug beispielsweise ein Prepreg sein. Dies bedeutet, dass das Faserhalbzeug ein textiles Fasermaterial umfasst, welches bereits mit einer Matrix vorimprägniert ist und dem beschriebenen Verfahren zugeführt wird.For example, the semi-finished fiber product may be a prepreg. This means that the semifinished fiber product comprises a textile fiber material which is already preimpregnated with a matrix and fed to the described method.

Alternativ kann das Presswerkzeug ein Nasspresswerkzeug sein, wobei ein Auftragen von Matrix auf das Faserhalbzeug vor oder nach dem Einbringen in das geöffnete Presswerkzeug erfolgt. Dies bedeutet, dass das Faserhalbzeug in einem matrix-freien Zustand, also in einem „trockenen“ Zustand vorliegt und die Matrix unmittelbar vor dem Einbringen in das Presswerkzeug oder nach dem Einbringen in das Presswerkzeug auf das trockene Faserhalbzeug aufgebracht wird. Das Presswerkzeug befindet sich hierbei noch im geöffneten Zustand.Alternatively, the pressing tool may be a wet pressing tool, wherein a matrix is applied to the semifinished fiber product before or after being introduced into the opened pressing tool. This means that the semifinished fiber product is in a matrix-free state, ie in a "dry" state, and the matrix is applied to the dry semifinished fiber product immediately prior to introduction into the pressing tool or after introduction into the pressing tool. The pressing tool is still in the open state.

Ist das Verfahren dagegen als RTM-Prozess ausgestaltet, so stellt das Presswerkzeug ein RTM-Werkzeug dar, wobei ein Injizieren von Matrix in das Faserhalbzeug während des Pressens erfolgt. Dies bedeutet, dass das Faserhalbzeug in trockenem Zustand in das Presswerkzeug eingelegt und dieses geschlossen wird. Anschließend wird die Matrix in die durch das Presswerkzeug gebildete Kavität eingeleitet und auf diese Weise in das Faserhalbzeug injiziert.On the other hand, if the method is designed as an RTM process, then the pressing tool represents an RTM tool, wherein an injection of matrix into the semifinished fiber product takes place during the pressing. This means that the semifinished fiber product is inserted in the dry state in the pressing tool and this is closed. Subsequently, the matrix is introduced into the cavity formed by the pressing tool and injected in this way into the semi-finished fiber product.

In jedem Fall kann das Faserhalbzeug zum Beispiel ein Gewebe, Gelege, Gesticke, Geflecht oder ein Vlies sein. Als Verstärkungsfasern des Faserhalbzeugs können insbesondere Glasfasern, Kohlefasern, Aramidfasern, Naturfasern oder andere geeignete Verstärkungsfasern eingesetzt werden. In any case, the semifinished fiber product can be, for example, a woven, scrim, embroidery, braid or a fleece. In particular glass fibers, carbon fibers, aramid fibers, natural fibers or other suitable reinforcing fibers can be used as reinforcing fibers of the semifinished fiber product.

Wie beschrieben kann der mindestens eine Verbindungsfortsatz von einer Oberfläche des Metallelements abstehend ausgebildet sein. Vorzugsweise steht der mindestens eine Verbindungsfortsatz jeweils unter einem Winkel von 1° ≤ α ≤ 90°, besonders bevorzugt unter einem Winkel von 45° ≤ α ≤ 90° bezüglich der Oberfläche des Metallelements von dieser ab. Besonders einfach ist ein Einstecken des mindestens einen Verbindungsfortsatzes in das Faserhalbzeug möglich, wenn dieser bezüglich der Oberfläche des Metallelements im Wesentlichen rechtwinklig, also mit einem Winkel α von α = ca. 90°, angeordnet ist. Das Metallelement kann in diesem Fall besonders einfach in das Faserhalbzeug eingesteckt werden, insbesondere wenn das Metallelement eine große Anzahl von Verbindungsfortsätzen umfasst.As described, the at least one connection extension may be formed projecting from a surface of the metal element. The at least one connecting extension preferably protrudes at an angle of 1 ° ≦ α ≦ 90 °, particularly preferably at an angle of 45 ° ≦ α ≦ 90 ° with respect to the surface of the metal element. Inserting the at least one connecting extension into the semi-finished fiber product is particularly easy if it is arranged substantially at right angles with respect to the surface of the metal element, that is to say at an angle α of approximately 90 °. In this case, the metal element can be inserted particularly easily into the semi-finished fiber product, in particular if the metal element comprises a large number of connecting extensions.

Gemäß einer Ausführungsform kann das Metallelement als flächiges Bauteil ausgebildet sein. In diesem Fall ist das Metallelement zum Beispiel plattenförmig ausgebildet und weist auf einer Oberfläche den einen Verbindungsfortsatz oder die mehreren Verbindungsfortsätze auf, die in dem Verbindungsabschnitt angeordnet sind. Das flächig ausgebildete Metallelement lässt sich besonders einfach mit dem Faserhalbzeug verpressen, so dass beide Komponenten über eine flächige und damit besonders belastbare Verbindung zusammengehalten werden.According to one embodiment, the metal element may be formed as a flat component. In this case, the metal element is, for example, plate-shaped and has, on a surface, the one connection extension or the plurality of connection extensions arranged in the connection section. The flat metal element can be particularly easily pressed with the semifinished fiber, so that both components are held together by a flat and therefore particularly strong connection.

Der mindestens eine Verbindungsfortsatz kann auf unterschiedliche Weise erzeugt werden. Zum Beispiel kann ein separat hergestellter Verbindungsfortsatz mit der Oberfläche des Metallelements verbunden werden, insbesondere durch Schweißen oder Kleben.The at least one connection extension can be generated in different ways. For example, a separately prepared connection extension can be connected to the surface of the metal element, in particular by welding or gluing.

Vorzugsweise kann alternativ der Schritt des Bereitstellens des Metallelements ein Stanzen des Metallelements zum Ausbilden des mindestens einen Verbindungsfortsatzes an dem Metallelement umfassen. Dies bedeutet, dass der mindestens eine Verbindungsfortsatz aus dem Metallelement ausgestanzt wird. Das Stanzen kann derart erfolgen, dass lediglich ein Teilabschnitt einer Kontur des jeweiligen Verbindungsfortsatzes ausgestanzt wird, so dass dieser mit einem verbleibenden Abschnitt mit dem restlichen Metallelement verbunden bleibt. In diesem Fall kann der jeweilige Verbindungsfortsatz in dem verbleibenden Abschnitt umgebogen und so ein gewünschter Winkel α bezüglich der Oberfläche des Metallelements eingestellt werden. Der Schritt des Stanzens ermöglicht eine besonders einfache, zuverlässige und günstige Art der Herstellung und Ausbildung des jeweiligen Verbindungsfortsatzes.Preferably, alternatively, the step of providing the metal element may include stamping the metal element to form the at least one connection extension on the metal element. This means that the at least one connection extension is punched out of the metal element. The punching can be done such that only a portion of a contour of the respective connection extension is punched out, so that it remains connected to a remaining portion with the remaining metal element. In this case, the respective connection extension can be bent in the remaining portion and thus set a desired angle α with respect to the surface of the metal element. The step of punching allows a particularly simple, reliable and inexpensive way of producing and forming the respective connecting extension.

Um das Risiko einer möglichen Kontaktkorrosion zwischen dem Metallelement und dem Faserhalbzeug zu vermeiden, kann der Schritt des Bereitsteilens des Metallelements einen Schritt des Beschichtens des Metallelements mit einer das Metallelement zumindest in dem Verbindungsabschnitt bedeckenden Beschichtung umfassen. Auf diese Weise wird das Metallelement zumindest in dem Verbindungsabschnitt durch die Beschichtung von den Verstärkungsfasern des Faserhalbzeugs abgetrennt, so dass elektrochemische Reaktionen zwischen den beiden Komponenten, insbesondere bei einer Verwendung von Kohlefasern, vermieden werden können.In order to avoid the risk of possible contact corrosion between the metal element and the semifinished fiber product, the step of providing the metal element may comprise a step of coating the metal element with a coating covering the metal element at least in the connection section. In this way, the metal element is separated at least in the connecting portion by the coating of the reinforcing fibers of the semifinished fiber, so that electrochemical reactions between the two components, in particular when using carbon fibers, can be avoided.

Als Beschichtung für das Metallelement eignen sich zum Beispiel eine oberflächliche Verzinkung oder eine Chrom-Nickel Legierung.As a coating for the metal element, for example, a surface galvanizing or a chromium-nickel alloy are suitable.

Wird der jeweilige Verbindungsfortsatz durch Stanzen aus dem Metallelement erzeugt, so wird die Beschichtung vorzugsweise erst nach einem Umbiegen des Verbindungsfortsatzes aufgebracht, um Fehlstellen in der Beschichtung aufgrund des Biegevorgangs zu vermeiden. Selbstverständlich ist dennoch eine entsprechende Beschichtung vor dem Stanzen möglich.If the respective connection extension is produced by stamping from the metal element, then the coating is preferably applied only after a bending over of the connection extension in order to avoid defects in the coating due to the bending process. Of course, a corresponding coating is still possible before punching.

Des Weiteren wird ein Hybridbauteil mit einem Metallelement und einem mit dem Metallelement verbundenen Faserverbundelement bereitgestellt, wobei das Hybridbauteil mit einem Verfahren gemäß dieser Beschreibung hergestellt ist. Das Faserverbundelement wird durch das Faserhalbzeug erzeugt, welches das beschriebene Verfahren durchläuft und insbesondere mit einer Matrix beaufschlagt, verpresst und ausgehärtet wird.Furthermore, a hybrid component is provided with a metal element and a fiber composite element connected to the metal element, wherein the hybrid component is produced by a method according to this description. The fiber composite element is produced by the semi-finished fiber product, which passes through the described method and in particular applied with a matrix, pressed and cured.

Mit Hilfe des beschriebenen Verfahrens kann nun ein Hybridbauteil, also ein Kombinationsbauteil aus Metall und Faserverbundmaterial, in einem einfachen Pressprozess hergestellt werden. Gleichzeitig kann auf aufwendige Klebeprozesse einschließlich der hierfür erforderlichen Reinigung der Bauteile, oder ein Bohren und Nieten verzichtet werden. Dementsprechend vereinfacht sich der Bedarf an Fertigungsanlagen, da entsprechende Waschanlagen, Strahlanlagen sowie Klebeanlagen oder Nietzellen entfallen.With the aid of the method described, a hybrid component, that is to say a combination component made of metal and fiber composite material, can now be produced in a simple pressing process. At the same time can be dispensed with consuming adhesive processes including the necessary cleaning of the components, or drilling and riveting. Accordingly, the need for manufacturing facilities simplifies, since corresponding washing systems, blasting systems and adhesive systems or rivets omitted.

Die Erfindung wird nachfolgend anhand zweier Ausführungsbeispiele unter Bezugnahme auf die Zeichnungen näher erläutert. Es zeigen:

Zunächst erfolgt ein Bereitstellen eines Metallelements 21, welches in der dargestellten Ausführungsform als flächiges Bauteil ausgebildet ist und einen Verbindungsabschnitt 22 aufweist. Der Verbindungsabschnitt 22 ist zum Verbinden mit einem Faserhalbzeug 23 ausgebildet und umfasst zwei jeweils plastisch verformbare Verbindungsfortsätze 24. Selbstverständlich können ebenso lediglich ein einzelner oder eine Vielzahl von mehr als zwei Verbindungsfortsätzen 24 in gleicher Weise vorgesehen werden.First, a provision of a metal element takes place 21 , which is formed in the illustrated embodiment as a flat component and having a connecting portion 22. The connecting section 22 is for connecting to a semi-finished fiber 23 formed and includes two each plastically deformable connection extensions 24 , Of course, as well, only a single or a plurality of more than two connection extensions 24 can be provided in the same way.

Das Metallelement 21 und das Faserhalbzeug 22 werden in das geöffnete Presswerkzeug 10 gemäß 1 eingebracht, wobei die beiden Verbindungsfortsätze 24 in das Faserhalbzeug 23 nicht nur hineinragen, sondern sich jeweils durch dieses (in einer Dickenrichtung des Faserhalbzeugs 23) hindurch erstrecken und auf einer dem Metallelement 21 abgewandten Oberfläche (einer Oberseite 23a des Faserhalbzeugs 23), aus dem Faserhalbzeug 23 austreten. Das Metallelement 21 und das Faserhalbzeug 23 werden also einzeln in das Presswerkzeug 10 eingebracht, wobei die beiden Verbindungsfortsätze 24 jeweils in das Faserhalbzeug 23 eingesteckt werden.The metal element 21 and the semifinished fiber product 22 are in the open die 10 according to 1 introduced, wherein the two connection extensions 24 in the semifinished fiber product 23 not only protrude, but each through this (in a thickness direction of the semifinished fiber 23 ) and on a metal element 21 opposite surface (a top 23a of the semifinished fiber product 23 ), from the semifinished fiber product 23 escape. The metal element 21 and the semifinished fiber product 23 So they are individually in the press tool 10 introduced, wherein the two connecting extensions 24 each in the semifinished fiber product 23 be plugged in.

Alternativ und daher nicht dargestellt könnte das Metallelement 21 ebenso mit den beiden Verbindungsfortsätzen 24 in das Faserhalbzeug 23 bereits vorab eingesteckt und erst anschließend gemeinsam in das geöffnete Presswerkzeug 10 eingebracht werden.Alternatively, and therefore not shown, the metal element could 21 as well with the two connection extensions 24 in the semifinished fiber product 23 already inserted in advance and then introduced together into the open pressing tool 10.

In der in 1 und 2 dargestellten Ausführungsform wird das Metallelement 21 zunächst auf dem Unterwerkzeug 11 aufgelegt, wobei der Verbindungsabschnitt 22 und die beiden Verbindungsfortsätze 24 mit ihren jeweiligen freien Enden 24a im Wesentlichen in Richtung des Oberwerkzeugs 12 und damit gleichzeitig entgegen einer Schließrichtung S des Presswerkzeugs 10 gerichtet sind. Auf den Verbindungsabschnitt 22 wird das Faserhalbzeug 23 aufgelegt. In der dargestellten Ausführungsform stellt der Verbindungsabschnitt 22, auf dem das Faserhalbzeug 23 angeordnet wird, lediglich einen Teilabschnitt einer Oberfläche 21a des Metallelements 21 dar, so dass das Faserhalbzeug 23 lediglich teilweise mit dem Metallelement 21 überlappend angeordnet wird.In the in 1 and 2 illustrated embodiment, the metal element 21 first on the lower tool 11 placed, wherein the connecting portion 22 and the two connecting extensions 24 with their respective free ends 24a essentially in the direction of the upper tool 12 and thus simultaneously against a closing direction S of the pressing tool 10 are directed. On the connecting section 22 becomes the semifinished fiber product 23 hung up. In the illustrated embodiment, the connecting portion 22, on which the semifinished fiber product 23 is arranged, only a portion of a surface 21a of the metal element 21 is, so that the semi-finished fiber 23 only partially with the metal element 21 is arranged overlapping.

Lediglich beispielhaft ist auf der Oberseite 23a des Faserhalbzeugs 23 eine Matrix 25 aufgetragen, so dass ein anschließendes Verpressen als Nasspressprozess durchgeführt werden kann, wodurch die Matrix 25 in das Faserhalbzeug 23 eingebracht wird. Der Auftrag der Matrix 25 kann zu Beispiel vor dem Einlegen in das Presswerkzeug 10 oder nach erfolgtem Einlegen bei geöffnetem Presswerkzeug 10 erfolgen.Only an example is on the top 23a of the semifinished fiber product 23 applied a matrix 25, so that a subsequent pressing can be carried out as a wet pressing process, whereby the matrix 25 is introduced into the semi-finished fiber 23. The order of the matrix 25 For example, before inserting into the press tool 10 or after loading with open pressing tool 10 respectively.

Alternativ und daher nicht dargestellt, kann das Faserhalbzeug 23 aber auch als sogenannter Prepreg bereits mit der Matrix 25 vorimprägniert sein und in diesem mit der Matrix 25 getränkten Zustand auf gleiche Weise in das Presswerkzeug 10 eingelegt werden. In diesem Fall kann der Schritt des Auftragens einer Matrix 25 auf die Oberseite 23a des Faserhalbzeugs 23 entfallen. Als weitere Alternative kann die Matrix 25 erst bei geschlossenem Presswerkzeug 10 (Zustand gemäß 2) im Rahmen eines sogenannten RTM-Prozesses in das Faserhalbzeug 23 injiziert werden, so dass solange sich das Presswerkzeug 10 im geöffneten Zustand befindet, das Faserhalbzeug 23 noch in einem trockenen, matrix-freien Zustand, vorliegt.Alternatively, and therefore not shown, the semi-finished fiber can 23 but also as a so-called prepreg already with the matrix 25 be preimpregnated and in this with the matrix 25 soaked state can be inserted in the same manner in the pressing tool 10. In this case, the step of applying a matrix 25 on top 23a of the semifinished fiber product 23 omitted. As another alternative, the matrix 25 only when the pressing tool 10 is closed (condition according to FIG 2 ) as part of a so-called RTM process in the semifinished fiber product 23 be injected, so as long as the pressing tool 10 is in the open state, the semi-finished fiber 23 is still in a dry, matrix-free state.

Gemäß der dargestellten Ausführungsform erfolgt nachfolgend zu dem Schritt des Einbringens ein in 2 dargestelltes Schließen des Presswerkzeugs 10 und ein Pressen des Metallelements 21 und des Faserhalbzeugs 23 zum Erzeugen des Hybridbauteils 20, wobei die beiden Verbindungsfortsätze 24 hierbei plastisch umgeformt werden, um eine formschlüssige Verbindung des Metallelements 21 mit dem Faserhalbzeug 23 bereitzustellen. Im Rahmen des Pressschrittes erfolgt ein Pressen der beiden Verbindungsfortsätze 24 gegen in dem Presswerkzeug 10 ausgebildete, definierte Umformflächen 12a, wodurch die beiden Verbindungsfortsätze 24 jeweils zunächst quer zu und anschließend in Schließrichtung S des Presswerkzeugs 10 umgeformt werden. Hierzu sind die definierten Umformflächen 12a jeweils durch eine Ausnehmung im Oberwerkzeug 12 des Presswerkzeugs 10 gebildet und weisen jeweils eine konkave Form auf. Die Verbindungsfortsätze 24 werden klammerförmig umgeformt und umgreifen Fasern des Faserhalbzeugs 23, wodurch das Faserhalbzeug 23 an dem Metallelement 21 „festgeklammert“ wird.According to the illustrated embodiment, following in the step of introducing a in 2 illustrated closing of the pressing tool 10 and pressing the metal element 21 and the semifinished fiber product 23 for producing the hybrid component 20 , wherein the two connection extensions 24 are plastically deformed in this case to form-fit connection of the metal element 21 with the semifinished fiber product 23 provide. As part of the pressing step, a pressing of the two connection extensions 24 takes place against in the pressing tool 10 trained, defined forming surfaces 12a, whereby the two connecting extensions 24 each first transverse to and then in the closing direction S of the pressing tool 10 be transformed. These are the defined forming surfaces 12a each through a recess in the upper tool 12 of the pressing tool 10 formed and each have a concave shape. The connection extensions 24 be transformed into a clamp shape and encompass fibers of the semifinished fiber product 23 , whereby the semifinished fiber product 23 on the metal element 21 "Clamped" is.

Im Rahmen des Pressens wird zudem die Matrix 25 des Faserhalbzeugs 23 zumindest teilweise ausgehärtet, unabhängig von der Art des verwendeten Verfahrens zum Einbringen der Matrix 25 auf beziehungsweise in das Faserhalbzeug 23.As part of the pressing, the matrix also becomes 25 of the semifinished fiber product 23 at least partially cured, regardless of the type of method used to introduce the matrix 25 on or in the semi-finished fiber product 23.

Sobald das Hybridbauteil 20 vollständig oder zumindest teilweise ausgehärtet ist, kann ein Entnehmen des erzeugten Hybridbauteils 20 aus dem Presswerkzeug 10 erfolgen.Once the hybrid component 20 completely or at least partially cured, a removal of the hybrid component produced 20 take place from the pressing tool 10.

Wie aus 1 beispielhaft erkennbar, können die beiden Verbindungsfortsäte 24 jeweils von der Oberfläche 21a des Metallelements 21 abstehend ausgebildet sein. Hierbei können diese einen Winkel von 1° ≤ α ≤ 90°, besonders bevorzugt unter einem Winkel von 45° ≤ α ≤ 90° bezüglich der Oberfläche 21a aufweisen. Dargestellt ist rein beispielhaft ein jeweiliger Winkel α von α = ca. 90°, wodurch ein Einstecken in das Faserhalbzeug 23 besonders erleichtert wird.How out 1 can be seen by way of example, the two Verbindungsfortsäte 24 each of the surface 21a of the metal element 21 be formed projecting. In this case, they can have an angle of 1 ° ≦ α ≦ 90 °, particularly preferably at an angle of 45 ° ≦ α ≦ 90 ° with respect to the surface 21a exhibit. Illustrated purely by way of example is a respective angle α of α = about 90 °, whereby an insertion into the semifinished fiber product 23 is particularly relieved.

3 zeigt eine alternative Ausführungsform eines Metallelements 31 für das Hybridbauteil 20 beziehungsweise das zu den 1 und 2 beschriebene Verfahren zur Herstellung des Hybridbauteils 20. Demnach ist das Metallelement 31 gemäß dieser zweiten Ausführungsform ebenfalls als flächiges Bauteil ausgebildet und somit im Wesentlichen plattenförmig. Ein Verbindungsabschnitt 32 zum Verbinden mit dem Faserhalbzeug 23 erstreckt sich über die gesamte dargestellte Oberseite 31a des Metallelements 31. Wie aus 3 erkennbar, wurde das Metallelement 31 für den Schritt des Bereitstellens des Metallelements 31 zunächst einem Schritt des Stanzens unterzogen, um die jeweiligen Verbindungsfortsätze 34 an dem Metallelement 31 auszubilden. 3 shows an alternative embodiment of a metal element 31 for the hybrid component 20 or the to the 1 and 2 described method for producing the hybrid component 20 , Accordingly, the metal element 31 according to this second embodiment is also formed as a planar component and thus substantially plate-shaped.
