Description
Die Erfindung betrifft ein Fahrwerksbauteil für ein Kraftfahrzeug aus einem kurzfaserverstärkten Kunststoff gemäß der im Oberbegriff des Patentanspruches
Die
Die
Die US 2014 / 0 145 374 A1 beschreibt ferner ein Verfahren zum Spritzgießen von thermoplastischem Kunststoff.US 2014/01445374 A1 also describes a method for injection molding thermoplastic material.
Der Erfindung liegt die Aufgabe zugrunde, ein Fahrwerksbauteil für ein Kraftfahrzeug aus einem kurzfaserverstärkten Kunststoff derart weiterzubilden, dass das Fahrwerksbauteil ein geringes Bauteilgewicht und eine hohe mechanische Festigkeit aufweist und dass zudem eine einfache, kostengünstige Herstellung gewährleistet ist.The invention is based on the object of developing a chassis component for a motor vehicle from a short fiber-reinforced plastic in such a way that the chassis component has a low component weight and high mechanical strength and that simple, inexpensive production is also ensured.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 in Verbindung mit seinen Oberbegriffsmerkmalen gelöst.This object is achieved by the characterizing features of claim 1 in conjunction with the features of the preamble.
Der Unteranspruch bildet eine vorteilhafte Weiterbildung der Erfindung.The dependent claim forms an advantageous development of the invention.
Erfindungsgemäß weist das Fahrwerksbauteil für ein Kraftfahrzeug aus einem kurzfaserverstärkten Kunststoff mindestens einen in einem ersten Spritzgussvorgang hergestellten Kern und mindestens eine, in einem zweiten Spritzgussvorgang hergestellte, den Kern umhüllende Umspritzung auf, wobei der Kern und die Umspritzung aus dem gleichen kurzfaserverstärkten Kunststoff bestehen und die Kurzfasern des kurzfaserverstärkten Kunststoffs im Kern und in der Umspritzung in einer Gleiche, vordefinierte Richtung ausgerichtet sind, wobei der Kern und die Umspritzung eine Bauteildicke ≤ 2mm aufweisen.According to the invention, the chassis component for a motor vehicle made of a short-fiber-reinforced plastic has at least one core produced in a first injection molding process and at least one encapsulation surrounding the core produced in a second injection-molding process, the core and the encapsulation being made of the same short-fiber-reinforced plastic and the short fibers of the short fiber reinforced plastic in the core and in the overmolding are aligned in the same, predefined direction, the core and the overmolding having a component thickness of ≤ 2mm.
Während nach der Lehre des Stands der Technik bei einem aus einem kurzfaserverstärkten Kunststoff hergestellten Fahrwerksbauteil die geforderte mechanische Festigkeit über Verrippungen erreicht wird, weist die erfindungsgemäße Lehre in eine andere Richtung:
- Gemäß der Erfindung wird die geforderte mechanische Festigkeit dadurch erreicht, dass die Kurzfasern des kurzfaserverstärkten Kunststoffs entlang einer vordefinierte Belastungslinie ausgerichtet sind. Dies ist erfindungsgemäß durch den speziellen Aufbau des Fahrwerksbauteils gewährleistet, nämlich dadurch, dass mindestens ein Kern und mindestens eine den Kern umhüllende Umspritzung, jeweils aus dem gleichen kurzfaserverstärkten Kunststoff, vorgesehen sind. Durch diesen Aufbau ist in vorteilhafte Weise gewährleistet, dass Kern und Umspritzung ausreichend dünn ausgebildet sein können, um beim Spritzvorgang auftretende Verwirbelungen der Kurzfasern ausschließen zu können. Ein weiterer Vorteil ist, dass aufgrund des Wegfalls der Rippenstruktur beim erfindungsgemäßen Fahrwerksbauteil ein geringerer Materialeinsatz notwendig ist, sodass das Bauteil leichter und damit kostengünstiger ist und zudem eine geringere Bauhöhe aufweist. Vorteilhaft ist weiterhin, dass aufgrund der nunmehr nicht mehr vorhandenen Verrippungen eine einfache und kostengünstige Gestaltung des Spritzwerkzeuges ermöglicht ist.
- According to the invention, the required mechanical strength is achieved in that the short fibers of the short fiber reinforced plastic are aligned along a predefined load line. According to the invention, this is ensured by the special structure of the chassis component, namely in that at least one core and at least one extrusion coating that envelops the core, each made of the same short-fiber-reinforced plastic, are provided. This structure advantageously ensures that the core and extrusion coating can be made sufficiently thin in order to be able to exclude turbulence of the short fibers that occurs during the injection molding process. Another advantage is that, because the rib structure is omitted, less material is required in the chassis component according to the invention, so that the component is lighter and therefore more cost-effective and also has a lower overall height. It is also advantageous that, because the ribs are no longer present, a simple and inexpensive design of the injection molding tool is made possible.
Da der Kern und die Umspritzung eine Bauteildicke ≤ 2mm aufweisen, ist in vorteilhafterweise gewährleistet, dass Verwirbelungen der Kurzfasern im Spritzwerkzeug vermieden werden und damit die definierte Ausrichtung der Kurzfasern gewährleistet ist.Since the core and the encapsulation have a component thickness of 2mm, it is advantageously ensured that turbulence of the short fibers in the injection molding tool is avoided and thus the defined alignment of the short fibers is guaranteed.
Unter einem kurzfaserverstärkten Kunststoff sollen vorliegend insbesondere ein kohlenstofffaserverstärkter Kunststoff (CFK), glasfaserverstärkter Kunststoff (GFK) sowie aramitfaserverstärkter Kunststoff (AFK), mit einer Faserlänge zwischen 0,1 bis 1mm, verstanden werden.A short fiber reinforced plastic is to be understood in the present case in particular as a carbon fiber reinforced plastic (CFRP), glass fiber reinforced plastic (GFRP) and aramid fiber reinforced plastic (AFK) with a fiber length between 0.1 and 1mm.
Gemäß einer vorteilhaften Ausführungsform der Erfindung weist der Kern in seiner Oberfläche rillenförmige Vertiefungen auf. Durch die rillenförmigen Vertiefungen ist in vorteilhafte Weise eine hochbelastbare Verbindung zwischen Kern und Umspritzung sichergestellt.According to an advantageous embodiment of the invention, the core has groove-shaped depressions in its surface. The groove-shaped depressions advantageously ensure a heavy-duty connection between the core and the encapsulation.
Ein Verfahren zur Herstellung eines Fahrwerksbauteils für ein Kraftfahrzeug aus einem kurzfaserverstärkten Kunststoff umfasst die Verfahrensschritte Spritzgießen des Kerns in einem ersten Spritzgussvorgang und dem anschließenden Spritzgießen der Umspritzung in einem zweiten Spritzgussvorgang, wobei der Spritzgussvorgang jeweils so erfolgt, dass die Kurzfasern des kurzfaserverstärkten Kunststoffs im Kern und in der Umspritzung entlang einer gleichen vordefinierten Richtung ausgerichtet werden.A method for producing a chassis component for a motor vehicle from a short fiber reinforced plastic comprises the process steps of injection molding the core in a first injection molding process and the subsequent injection molding of the overmolding in a second injection molding process, the injection molding process being carried out in such a way that the short fibers of the short fiber reinforced plastic in the core and be aligned in the encapsulation along the same predefined direction.
Dabei werden beim Spritzgussvorgang die Kurzfasern des kurzfaserverstärkten Kunststoffs entlang der Spritzrichtung ausgerichtet. Dies erweist sich als vorteilhaft, da nunmehr auf eine einfache Art und Weise die Ausrichtung der Kurzfasern ermöglicht ist.During the injection molding process, the short fibers of the short fiber reinforced plastic are aligned along the injection direction. This proves to be advantageous since the alignment of the short fibers is now made possible in a simple manner.
Um beim Spritzgussvorgang eine Verwirbelung der Kurzfasern zu vermeiden, werden Kern und Umspritzung mit einer Bauteildicke ≤ 2mm hergestellt.In order to avoid turbulence in the short fibers during the injection molding process, the core and overmolding are manufactured with a component thickness ≤ 2mm.
