Abstract
Description
Die Erfindung betrifft ein Kunststoff-Bauteil gemäß dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zur Herstellung eines solchen Kunststoff-Bauteils gemäß dem Oberbegriff des Anspruchs 9.The invention relates to a plastic component according to the preamble of claim 1 and a method for producing such a plastic component according to the Preamble of claim 9.
Es ist bereits bekannt, bei Kunststoff-Bauteilen, die eine Trägerschicht aus unverstärkten Kunststoffen aufweisen, eine thermoplastische Folie als Oberflächenschicht einzusetzen.It is already known for plastic components that have a carrier layer have unreinforced plastics, a thermoplastic film as Use surface layer.
Ferner sind Kunststoff-Bauteile bekannt, die durch eine hohe Faserverstärkung mit einem Faservolumengehalt von mindestens 30 Prozent entsprechend hohe mechanische Eigenschaften aufweisen. Die Oberfläche eines solchen hochfaserverstärkten Kunststoff-Bauteils erfordert jedoch eine aufwendige Nachbearbeitung, um eine hohe Oberflächenqualität, z. B. Class-A, zu erreichen.Furthermore, plastic components are known which have a high fiber reinforcement correspondingly high fiber volume content of at least 30 percent have mechanical properties. The surface of one high-fiber reinforced plastic component, however, requires a complex Post-processing to ensure a high surface quality, e.g. B. Class-A to achieve.
Aufgabe der Erfindung ist es, ein Kunststoff-Bauteil zu schaffen, das hohe mechanische Eigenschaften und eine hohe Oberflächenqualität aufweist. Ferner ist es Aufgabe der Erfindung, ein Verfahren zur Herstellung eines solchen Kunststoff- Bauteils anzugeben.The object of the invention is to provide a plastic component that is high has mechanical properties and a high surface quality. Further is it is an object of the invention to provide a method for producing such a plastic Specify component.
Die Aufgabe zur Schaffung eines Kunststoff-Bauteils wird durch die Merkmale des Anspruchs 1 und die Aufgabe zur Angabe eines Verfahrens zur Herstellung eines solchen Bauteils wird durch die Merkmale des Anspruchs 9 gelöst.The task of creating a plastic component is characterized by the characteristics of the Claim 1 and the task of specifying a method for producing a such component is solved by the features of claim 9.
Durch den erfindungsgemäßen Aufbau eines Kunststoff-Bauteils ist es möglich, ein Hochleistungs-Verbundbauteil zu schaffen, das eine hohe Oberflächenqualität aufweist, bei dem eine flächige Nachbearbeitung entfällt. Das erfindungsgemäße Kunststoff-Bauteil ist vorteilhaft im Fahrzeugbau für solche Bauteile einsetzbar, die bei hohen mechanischen Eigenschaften eine hohe Oberflächenqualität erfordern. Solche Bauteile sind insbesondere die Frontklappe, das Dach, die Heckklappe, die Fahrzeugtüren, die hintere Seitenwand und der Seitenrahmen. Durch die Verwendung von Hochleistungs-Faserverbundwerkstoffen für die Trägerschicht des Kunststoff-Bauteils ergibt sich neben den hohen mechanischen Eigenschaften eine hohe Gewichtseinsparung. Durch den Entfall der Nachbearbeitung der Oberfläche vermindern sich die Herstellungskosten und Herstellungszeiten, so daß das erfindungsgemäße Kunststoff-Bauteile wirtschaftlich für die Fahrzeug-Außenhaut bzw. Teile davon eingesetzt werden kann.The construction of a plastic component according to the invention makes it possible to use a To create high-performance composite component that has a high surface quality has, in which a flat post-processing is not necessary. The invention Plastic component is advantageously used in vehicle construction for such components that require high surface quality with high mechanical properties. Such components are in particular the front flap, the roof, the tailgate, the Vehicle doors, the rear side wall and the side frame. Through the Use of high-performance fiber composite materials for the carrier layer of the Plastic component results in addition to the high mechanical properties high weight saving. By eliminating the need to rework the surface the manufacturing costs and manufacturing times decrease, so that Plastic components according to the invention economically for the vehicle outer skin or parts thereof can be used.
Als vorteilhaft hat sich das Injektionsverfahren zur Herstellung des erfindungsgemäßen Kunststoff-Bauteils herausgestellt, da durch das erfindungsgemäße Injektionsverfahren eine hohe Oberflächenqualität erzielbar ist.The injection method for producing the exposed plastic component according to the invention, because of that injection method according to the invention a high surface quality can be achieved.
Die Herstellung eines erfindungsgemäßen Kunststoff-Bauteils wird nachfolgend beispielshalber beschrieben. In das in der Regel zweiteilige Werkzeug wird je nach Bauteilgeometrie eine thermoplastische Folie unverformt oder vorumgeformt in das entsprechende Werkzeugteil eingelegt. Die Vorumformung der Folie kann beispielsweise in dem Werkzeug bzw. in einem Vorwerkzeug unter Wärmezufuhr erfolgen. Bei der Vorumformung erweicht die Folie nach einer entsprechenden Wärmezufuhr und die Folie paßt sich der durch das Werkzeug vorgegebenen Kontur an. Danach erfolgt eine Abkühlung der Folie, die zu einem Erstarren der Folie führt.The production of a plastic component according to the invention is as follows described as an example. In the usually two-part tool is depending on Component geometry a thermoplastic film undeformed or preformed into the appropriate tool part inserted. The film can be preformed for example in the tool or in a front tool with the supply of heat respectively. During pre-forming, the film softens after a corresponding one Heat supply and the film adapts to that specified by the tool Contour. This is followed by cooling of the film, which leads to a solidification of the Slide leads.
Nach dem Einlegen der Folie oder gleichzeitig mit dem Einlegen der Folie in das Werkzeug kommt das Fasermaterial für die Trägerschicht in das Werkzeug. Das Werkzeug wird geschlossen und das Matrixmaterial injiziert. Das Matrixmaterial kann ein duroplastischer oder ein thermoplastischer Kunststoff oder eine Kombination aus beiden Werkstoffen sein. Die Bauteilseite, die mit der Folie versehen ist, weist nach dem Herstellungsvorgang eine hohe Oberflächenqualität, z. B. Class-A, ohne das Erfordernis einer weiteren Nachbearbeitung auf. After inserting the film or simultaneously with the film in the The fiber material for the carrier layer comes into the tool. The The tool is closed and the matrix material is injected. The matrix material can be a thermosetting or a thermoplastic or Be a combination of both materials. The component side with the foil has a high surface quality after the manufacturing process, e.g. B. Class-A, without the need for further post-processing.
Gegebenenfalls kann die Folie auch gleich als Lackträgerfolie bzw. als Dekorfolie mit einer Lackbeschichtung ausgeführt sein, um den Lackiervorgang einzusparen. Andernfalls wird nachträglich lackiert.If necessary, the film can also be used as a lacquer carrier film or as a decorative film be carried out with a lacquer coating in order to save the painting process. Otherwise it will be painted later.
