Abstract

The method involves removing matrix materials at surfaces (2) of workpieces (1) in a joining zone chemically, thermally or mechanically to expose individual fibers (4). The fibers in the joining zone are impregnated by an auxiliary material, where organic sheets are used as the workpieces, and the auxiliary material is a thermoplastic or duroplastic auxiliary material. Adhesive is used as the auxiliary material. The workpieces are welded together with the auxiliary material that corresponds to the matrix materials of the workpieces.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Verbindung von zwei jeweils aus einem Faser-Kunststoff-Verbund bestehenden Werkstücken in einer Fügezone unter Verwendung eines Zusatzmaterials.The The invention relates to a method for connecting two each consisting of a fiber-plastic composite workpieces in a joining zone using a supplementary material.

Die DE 10 2005 054 502 A1 offenbart ein Verfahren zum Verbinden zweier Werkstücke mittels eines Zusatzmaterials, das eine geringere Schmelztemperatur, als die Materialien der Werkstücke aufweist. Mit dem Verfahren soll zum einen eine kraft- und formschlüssige Verbindung von Werkstücken und zum anderen deren zerstörungsfreie Trennung sichergestellt werden. Die Werkstücke weisen in der Fügezone Hinterschnitte oder eine eingearbeitete Oberflächenstruktur auf, in die das erwärmte Zusatzmaterial unter Druckeinwirkung eindringt. Nach dem Abkühlen sind die beiden Werkstücke fest miteinander verbunden. Durch die unterschiedlichen Schmelzpunkte der Werkstücke und des verwendeten Zusatzmaterials ist die Trennung der beiden Werkstücke nach einer Erwärmung des Zusatzmaterials möglich.The DE 10 2005 054 502 A1 discloses a method for joining two workpieces by means of a filler material having a lower melting temperature than the materials of the workpieces. With the method, on the one hand a non-positive and positive connection of workpieces and, secondly, their non-destructive separation should be ensured. The workpieces have in the joining zone undercuts or an incorporated surface structure, in which the heated additional material penetrates under pressure. After cooling, the two workpieces are firmly connected. Due to the different melting points of the workpieces and the additional material used, the separation of the two workpieces after heating of the additional material is possible.

Durch Schweißen miteinander verbundene Werkstücke, die jeweils aus einem Faser-Kunststoff-Verbund, insbesondere mit kontinuierlicher Faserverstärkung, bestehen, weisen bei einer Schweißverbindung nach dem Stand der Technik in der Fügezone an der Grenzfläche eine Schwachstelle auf, da hier keine Faserverstärkung vorhanden ist. Besonders problematisch erweist sich die Schwachstelle, wenn ein Zusatzmaterial zum Schweißen verwendet wird, das insbesondere bei Faser-Kunststoff-Verbunden mit einem hohen Faseranteil, beispielsweise größer 40%, erforderlich ist, da der an der Werkstückoberfläche für die Schweißung zur Verfügung stehende Polymeranteil im Laminat nicht ausreicht. Durch das Einbringen des Zusatzmaterials in einer im Verhältnis zu den Werkstückdicken verhältnismäßig dicken Schicht in die Fügezone entstehen je nach Lastangriff eine Lasterhöhung und zusätzliche Schälkräfte, die die Festigkeit der Schweißverbindung mit den ungünstig angeordneten Grenzflächen negativ beeinträchtigen.By Welding interconnected workpieces that each of a fiber-plastic composite, in particular with continuous Fiber reinforcement, consist in a welded joint according to the prior art in the joining zone at the interface a weak spot, because here no fiber reinforcement is available. The weak point proves to be particularly problematic when a filler material is used for welding, in particular in fiber-plastic composites with a high fiber content, for example greater than 40%, is required because of the workpiece surface available for welding Polymer content in the laminate is insufficient. By introducing the Additional material in one in relation to the workpiece thicknesses relatively thick layer in the Joining zone arise depending on the load attack a load increase and additional peeling forces that the Strength of the welded joint with the unfavorable arranged interfere with negative affect.

Es ist Aufgabe der Erfindung, ein Verfahren der eingangs genannten Art zu schaffen, mit dem die Verbindung von Werkstücken unter Ausbildung einer verhältnismäßig hoch belastbaren Fügezone möglich ist.It Object of the invention, a method of the aforementioned To create kind, with which the connection of workpieces under training of a relative high loadable joining zone is possible.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass Matrixmaterial an der Oberfläche mindestens eines der Werkstücke in der Fügezone abgetragen wird, um mindestens einzelne Fasern freizulegen.According to the invention the problem solved by the fact that matrix material at the Surface of at least one of the workpieces in the joining zone is removed to at least individual fibers expose.

Demnach befindet sich die durch Einbringung von Zusatzmaterial bedingte Grenzfläche nicht unmittelbar zwischen den zu verbindenden Werkstücken und das Zusatzmaterial kann sich mit den freigelegten Fasern verbinden, wodurch eine relativ hohe Festigkeit in der Fügezone erzielbar ist. Bei der Kraftübertragung von einem Werkstück zu dem anderen wirken stets die in dem Zusatzmaterial vorhandenen Fasern des einen Werkstückes mit. Selbstverständlich ist die Länge der Fasern derart auf die Breite der Fügezone abgestimmt, dass die freigelegten Fasern noch in das Matrixmaterial des Werkstückes eingebettet sind.Therefore is due to the introduction of additional material Interface not directly between the to be connected Workpieces and the additional material can become exposed with the Connecting fibers, resulting in a relatively high strength in the joint zone is achievable. In the power transmission of a workpiece to the other always have the existing in the additional material Fibers of a workpiece with. Of course is the length of the fibers to the width of the joint zone tuned that the exposed fibers are still in the matrix material of the workpiece are embedded.

In Ausgestaltung wird das Matrixmaterial an den Oberflächen beider Werkstücke abgetragen. Demnach imprägniert das Zusatzmaterial die Fasern der beiden Werkstücke und die in das Zusatzmaterial eingebetteten Fasern in der Fügezone werden zur Kraftübertragung zwischen den Werkstücken genutzt. Die Dicke der abzutragenden Schicht ist im Wesentlichen vom Aufbau des Laminats abhängig und beträgt beispielsweise zwischen 0,01 und 0,2 mm. Selbstverständlich wird die Menge des Zusatzmaterials in Abhängigkeit von der abgetragenen Schicht Matrixmaterial bestimmt.In Embodiment becomes the matrix material on the surfaces both workpieces removed. Accordingly impregnated the additional material the fibers of the two workpieces and the fibers embedded in the filler in the joint zone be used for power transmission between the workpieces used. The thickness of the layer to be removed is substantially depends on the structure of the laminate and is for example between 0.01 and 0.2 mm. Of course, the amount will be of the additional material as a function of the removed layer Matrix material determined.

Nach einer Weiterbildung wird das Matrixmaterial chemisch, thermisch oder mechanisch entfernt. Dem Fachmann sind eine Vielzahl von Methoden zum Abtragen von Matrixmaterial an der Oberfläche eines Werkstückes bekannt, bei denen die Fasern unbeschädigt freigelegt werden. Unter Einsatz eines Lasers kann das Matrixmaterial beispielsweise verdampft werden, wobei es nicht unbedingt nachteilig sein muss, wenn degeneriertes Matrixmaterial in geringen Mengen an den Fasern anhaftet.To In a further development, the matrix material is chemically, thermally or mechanically removed. A variety of methods for the Removal of matrix material on the surface of a workpiece known in which the fibers are exposed undamaged. Using a laser, the matrix material, for example vaporizing, but it does not necessarily have to be detrimental if degenerated matrix material in small quantities on the fibers adheres.

Um eine für eine feste Verbindung ausreichende Anzahl an Fasern zur Verfügung zu haben, wird bevorzugt das Matrixmaterial in einer Dicke abgetragen, die dem Durchmesser von mindestens einem Roving entspricht. Zweckmäßigerweise imprägniert das Zusatzmaterial die Fasern in der Fügezone. Sonach durchdringt das Zusatzmaterial die Fasern, um sämtliche vorhandenen Filamente zu benetzen. Damit ist eine innige Verbindung zwischen dem Zusatzmaterial und den Fasern sowie den Werkstücken sichergestellt.Around a sufficient number of fibers for a firm connection to have available, is preferably the matrix material abraded in a thickness corresponding to the diameter of at least one Roving corresponds. Appropriately impregnated the additional material the fibers in the joining zone. Sonach penetrates the filler the fibers to all existing To wet filaments. This is an intimate connection between the additional material and the fibers and the workpieces ensured.

Vorteilhafterweise werden als Werkstücke so genannte Organobleche verwendet. Bei einem an sich bekannten Organoblech handelt es sich um ein plattenförmiges Halbzeug aus Lagen von textilen Flächengebilden, die mit einem Matrixmaterial verfestigt sind.advantageously, are used as workpieces so-called organo sheets. In a known organo-sheet is a plate-shaped Semi-finished products made of layers of textile fabrics, which with solidified a matrix material.

Nach einer Weiterbildung kommt bei einem thermoplastischen Matrixmaterial ein thermoplastisches Zusatzmaterial zum Einsatz. Vorzugsweise entspricht das thermoplastische Zusatzmaterial mindestens einem der Matrixmaterialien der Werkstücke.According to a further development, a thermoplastic filler material is used in a thermoplastic matrix material. Preferably The thermoplastic additive material corresponds to at least one of the matrix materials of the workpieces.

In weiterer Ausgestaltung werden die Werkstücke gemeinsam mit dem Zusatzmaterial verschweißt. Zur Anwendung können sämtliche bekannten Kunststoffschweißverfahren kommen, insbesondere Ultraschallschweißen, Induktionsschweißen, Heizelementschweißen, Laserschweißen, Reibschweißen oder Infrarotschweißen. Sind die Fasern der Werkstücke leitfähig, zum Beispiel Kohlenstofffasern, kann das Aufschmelzen auch per Induktion erfolgen. Im Weiteren ist auch ein Aufschmelzen per Induktion oder Mikrowelle denkbar, wenn entsprechende Partikel im Matrixmaterial und/oder im Zusatzmaterial vorhanden sind.In Another embodiment, the workpieces are common welded with the additional material. Can be used all known plastic welding processes especially ultrasonic welding, induction welding, heating element welding, Laser welding, friction welding or infrared welding. Are the fibers of the workpieces conductive, for Example carbon fibers, melting can also be by induction respectively. Furthermore, a melting by induction or Microwave conceivable, if appropriate particles in the matrix material and / or are present in the additional material.

Selbstverständlich wird bei einem duroplastischen Matrixmaterial ein duroplastisches Zusatzmaterial verwendet. Alternativ kommt als Zusatzmaterial ein Klebstoff zum Einsatz.Of course is a thermoset in a thermosetting matrix material Additional material used. Alternatively comes as additional material Adhesive used.

Es versteht sich, dass die vorstehend genannten und nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen verwendbar sind. Der Rahmen der Erfindung ist nur durch die Ansprüche definiert.It It is understood that the above and below to be explained features not only in the specified Combination, but also usable in other combinations. The scope of the invention is defined only by the claims.

Die Erfindung wird im Folgenden anhand zweier Ausführungsbeispiele unter Bezugnahme auf die zugehörigen Zeichnungen näher erläutert. Es zeigt:The Invention will be described below with reference to two embodiments with reference to the accompanying drawings in more detail explained. It shows:

Bei einem Verfahren zur Verbindung von zwei jeweils aus einem Faser-Kunststoff-Verbund bestehenden Werkstücken 1 wird zunächst Matrixmaterial an der Oberfläche 2 der Werkstücke 1 in der Fügezone 3 abgetragen, um einzelne Fasern 4 freizulegen, wobei die Fasern 4 vorliegend so genannte Filamente von Rovings 5 sind. Selbstverständlich können die Fasern auch Langfasern, Endlosfasern oder Bestandteile von beliebigen textilen Strukturen, wie Gewirke, Gewebe, Gelege, Gestricke, Geflechte, Matten oder Vliese, sein. Im Werkstück nehmen die Fasern 4 die Kräfte auf, da die Fasern 4 eine höhere Festigkeit als das Matrixmaterial aufweisen. Das Freilegen der einzelnen Fasern 4 kann chemisch oder thermisch, insbesondere unter Verwendung eines Lasers, erfolgen, der das Matrixmaterial zum Verdampfen erhitzt.In a method for connecting two each consisting of a fiber-plastic composite workpieces 1 will first be matrix material on the surface 2 the workpieces 1 in the joining zone 3 worn away to individual fibers 4 expose the fibers 4 in the present case so-called filaments of rovings 5 are. Of course, the fibers may also be long fibers, continuous fibers or constituents of any textile structures, such as knitted fabrics, woven fabrics, scrims, knits, braids, mats or nonwovens. In the workpiece take the fibers 4 the forces on, because the fibers 4 have a higher strength than the matrix material.

Anschließend wird gemäß den 2 und 3 ein Zusatzmaterial 6 in einer Menge, die mindestens der Menge des verdampften Matrixmaterials entspricht, oder bei einem relativ großen Faservolumenanteil gemäß den 4 und 5 eine demgegenüber größere Menge des Zusatzmaterials 6 zum Imprägnieren der Fasern 4 aufgetragen. Vorliegend handelt es sich sowohl bei dem Matrixmaterial der beiden Werkstücke 1 als auch bei dem Zusatzmaterial 6 um einen thermoplastischen Kunststoff, wobei zum Imprägnieren der freiliegenden Fasern 4 zumindest das Zusatzmaterial 6 aufgeschmolzen wird. Je nach Kombination und Schichtdicken der vorhandenen Werkstoffe kann auch ein Aufschmelzen der Werkstücke 1 in einem oberflächennahen Randbereich erforderlich sein, der neue Grenzflächen 7 in der Fügezone 3 darstellt. Nach dem Fügen der Werkstücke 1 werden diese miteinander verschweißt, anschließend abgekühlt und konsolidiert. Hierbei bilden sich die beiden neuen Grenzflächen 7 aus, die innerhalb der Werkstücke 1 vorliegen. Dadurch, dass die Fasern 4 imprägniert werden, entsteht keine Grenzfläche in einer Ebene 8 zwischen den Werkstücken 1, sondern es wird quasi ein neuer, in sich homogener Fügepartner 9 aus einem Faser-Kunststoff-Verbund geschaffen, der mit den beiden Werkstücken 1 innerhalb von deren Bauteilgeometrie verschweißt wird. Mit den beiden Grenzflächen 7 und der Kraftübertragung über die in dem Fügepartner 9 verankerten Fasern 4 geht eine Erhöhung der Festigkeit der Schweißnaht gegenüber dem Stand der Technik einher.Subsequently, according to the 2 and 3 an additional material 6 in an amount corresponding at least to the amount of evaporated matrix material, or at a relatively large fiber volume fraction according to 4 and 5 a contrast, larger amount of the additional material 6 for impregnating the fibers 4 applied. In the present case, this concerns both the matrix material of the two workpieces 1 as well as the additional material 6 to a thermoplastic, wherein for impregnating the exposed fibers 4 at least the additional material 6 is melted. Depending on the combination and layer thicknesses of the existing materials can also be a melting of the workpieces 1 be required in a near-surface border area, the new interfaces 7 in the joining zone 3 represents. After joining the workpieces 1 these are welded together, then cooled and consolidated. This forms the two new interfaces 7 out, inside the workpieces 1 available. Because of the fibers 4 impregnated, there is no interface in a plane 8th between the workpieces 1 But it is almost a new, homogeneous joining partner 9 created from a fiber-plastic composite, with the two workpieces 1 is welded within their component geometry. With the two interfaces 7 and the power transmission over in the joining partner 9 anchored fibers 4 An increase in the strength of the weld is associated with the prior art.
