Description
Die Erfindung betrifft ein faserverstärktes Kraftfahrzeug-Sichtbauteil mit einer Mehrzahl von Lagen, von denen eine eine außenliegende Decklage ist, die eine lackierfähige Oberfläche bildet, wobei die Lagen durch Laminieren zusammengefügt sind. Die Erfindung betrifft des Weiteren ein Kraftfahrzeug sowie ein Verfahren zum Herstellen eines Kraftfahrzeugs.The invention relates to a fiber-reinforced motor vehicle viewing component with a plurality of layers, one of which is an outer cover layer forming a paintable surface, wherein the layers are joined together by lamination. The invention further relates to a motor vehicle and a method for producing a motor vehicle.
Es ist insbesondere bei hochwertigen Kraftfahrzeugen mit Sichtbauteilen wichtig, dass die Oberflächen (der Fachmann kennt Class-A-Oberflächen, die der Benutzer direkt sieht, und Class-B-Oberflächen) der Sichtbauteile möglichst wellenfrei sind und ein homogenes Spiegelungsverhalten haben. Dies hängt einerseits mit der Oberflächenqualität und andererseits mit der Lackierung zusammen.It is particularly important in high-quality motor vehicles with visible components that the surfaces (the skilled person knows Class A surfaces that the user sees directly, and Class B surfaces) of the visible components are as free of waves and have a homogeneous reflection behavior. This depends on the one hand with the surface quality and on the other hand with the paint job.
Bei der Darstellung einer Class-A-Oberfläche aus faserverstärkten Kunststoffen ist nach herkömmlichen Verfahren erheblicher Nacharbeitungsaufwand erforderlich. Die Faserabzeichnungen werden durch das Auftragen mehrerer Schichten Primer und Filler und anschließendem Schleifen vor der Bauteillackierung minimiert. Komplett kann die entstehende Oberflächenwelligkeit nach dem herkömmlichen Stand der Technik jedoch nicht verhindert werden.In the presentation of a Class A surface of fiber reinforced plastics, considerable reworking is required by conventional methods. Fiber coatings are minimized by applying multiple layers of primer and filler and then sanding before component painting. Completely, however, the resulting surface waviness according to the conventional prior art can not be prevented.
Dabei stellen die Faserabzeichnungen, auch Fibre-Read-Outs genannt, neben anderen Einflussfaktoren wie Faltenbildungen, Faserauskämmung, Sink-Marks oder Pinholes ein materialbedingtes Defektpotenzial dar, das schon während des Verarbeitungsprozesses zum Tragen kommt, da bei einer thermoplastischen Matrix eine deutliche Änderung des spezifischen Volumens stattfindet, während die Fasern nur eine geringe Wärmedehnung erfahren.The fiber markings, also known as fiber readouts, along with other influencing factors such as wrinkles, fiber combina- tion, sink marks or pinholes, represent a material-related defect potential that already comes into play during the manufacturing process, since with a thermoplastic matrix there is a clear change in the specific Volume takes place while the fibers undergo little thermal expansion.
Die
Es ist desweiteren bekannt, dass entsprechende Kraftfahrzeug-Sichtbauteile präzise lackiert werden müssen. Im Falle von Kunststoffteilen müssen diese für elektrostatische Lackierverfahren mit einem speziellen Leitprimer beschichtet werden. Dieser leitende Primer ist inklusive des zum Aufbringen notwendigen Beschichtungsvorgangs ein wesentlicher Kostenfaktor. Neben dem zusätzlichen Schritt des Aufbringens und des zusätzlichen Materials ist es notwendig, die Beschichtung vor der Lackierung anzuschleifen und zu füllern.It is also known that corresponding motor vehicle vision components must be precisely painted. In the case of plastic parts, they must be coated with a special conductive primer for electrostatic painting. This conductive primer, including the coating process necessary for application, is a significant cost factor. In addition to the additional step of applying and the additional material, it is necessary to grind and fill the coating prior to painting.
Des Weiteren ist es bekannt, dass entsprechende Verfahren ein Übersprühen zur Folge haben können. Übersprühen ist das Aufbringen von Farbe auf Bereiche, die in dem entsprechenden Lackiervorgang nicht lackiert werden sollen. Die hieraus hervorgehenden Karosserien sind ggf. nicht freigabetauglich und müssen nachgearbeitet oder aussortiert werden.Furthermore, it is known that corresponding methods can result in overspray. Overspray is the application of paint to areas that should not be painted in the corresponding painting process. The resulting bodies may not be suitable for release and must be reworked or sorted out.
Aufgabe der Erfindung ist es somit, ein faserverstärktes Kraftfahrzeug-Sichtbauteil, ein Kraftfahrzeug sowie ein Verfahren zum Herstellen eines Kraftfahrzeugs dahingehend weiterzubilden, dass eine bessere Lackierung des Kraftfahrzeug-Sichtbauteils bei gleichzeitig niedrigeren Kosten möglich ist.The object of the invention is thus to develop a fiber-reinforced motor vehicle vision component, a motor vehicle and a method for producing a motor vehicle to the effect that a better finish of the automotive viewing component is possible at the same time lower costs.
Die Aufgabe wird gelöst durch ein faserverstärktes Kraftfahrzeug-Sichtbauteil gemäß Anspruch 1, ein Kraftfahrzeug gemäß dem nebengeordneten Anspruch 7 sowie durch ein Verfahren zum Herstellen eines Kraftfahrzeugs gemäß dem nebengeordneten Anspruch 8. Weiterführende Ausgestaltungen sind Gegenstand der abhängigen Ansprüche.The object is achieved by a fiber-reinforced motor vehicle viewing component according to claim 1, a motor vehicle according to the independent claim 7 and by a method for manufacturing a motor vehicle according to the
Die Erfindung betrifft ein faserverstärktes Kraftfahrzeug-Sichtbauteil mit einer Mehrzahl von Lagen, von denen eine eine außenliegende Decklage ist, die eine lackierfähige Oberfläche bildet. Die Mehrzahl von Lagen werden durch Laminieren zusammengefügt.The invention relates to a fiber-reinforced motor vehicle viewing component with a plurality of layers, one of which is an outer cover layer, which forms a paintable surface. The plurality of layers are joined together by lamination.
Erfindungsgemäß ist vorgesehen, dass eine elektrisch leitende Schicht einlaminiert ist. Durch das Einlaminieren einer elektrisch leitenden Schicht kann ein faserverstärktes Kraftfahrzeug-Sichtbauteil angegeben werden, das ohne Behandlung mit Leitprimer direkt elektrostatisch lackierbar ist. Damit entfallen die Schritte des Aufbringens eines Leitprimers sowie des anschließenden Abschleifens und Füllerns der zu lackierenden Oberfläche vor der Lackierung. Insoweit können mit Hilfe des erfindungsgemäßen faserverstärkten Kraftfahrzeug-Sichtbauteils neben Materialien etliche Arbeitsschritte eingespart werden. Das Einbringen der elektrisch leitenden Schicht erlaubt ein unmittelbares Lackieren der lackierfähigen Oberfläche.According to the invention, it is provided that an electrically conductive layer is laminated. By laminating an electrically conductive layer, a fiber-reinforced motor vehicle viewing component can be specified which can be directly electrostatically painted without treatment with conductive primer. This eliminates the steps of applying a Leitprimers and the subsequent grinding and filling the surface to be painted before painting. In that regard, with the help of fiber-reinforced motor vehicle vision component according to the invention in addition to materials can be saved several steps. The introduction of the electrically conductive layer allows immediate painting of the paintable surface.
In einer ersten weiterführenden Ausgestaltung der Erfindung kann vorgesehen sein, dass die elektrisch leitende Schicht ein elektrisch leitendes Vlies ist. Ein elektrisch leitendes Vlies lässt sich genauso wie andere Lagen des Kraftfahrzeug-Sichtbauteils formen und laminieren. Eine tiefgreifende Veränderung des an sich bekannten Herstellprozesses faserverstärkter Kraftfahrzeug-Sichtbauteile ist daher im Rahmen der Erfindung nicht notwendig.In a first further embodiment of the invention it can be provided that the electrically conductive layer is an electrically conductive fleece. An electrically conductive web can be shaped and laminated as well as other layers of the automotive vision component. A profound Modification of the known manufacturing process of fiber-reinforced motor vehicle vision components is therefore not necessary in the context of the invention.
In einer weiterführenden möglichen Ausgestaltung des faserverstärkten Kraftfahrzeug-Sichtbauteils kann vorgesehen sein, dass in das elektrisch leitende Vlies Metallfäden eingebracht, insbesondere eingefilzt sind. Die Metallfäden können in ausreichender Dichte eine elektrische Leitung durch die komplette Schicht und ohne flächige Abrisse sicherstellen.In a further possible embodiment of the fiber-reinforced motor vehicle viewing component can be provided that introduced into the electrically conductive non-woven metal filaments, in particular are felted. The metal filaments can ensure electrical conduction through the complete layer and without extensive discontinuities in sufficient density.
In einer weiterführenden Ausgestaltung kann vorgesehen sein, dass die elektrisch leitende Schicht unmittelbar unter der Decklage angeordnet ist. Auf diese Weise findet keine wesentliche Dämpfung der elektrostatischen Eigenschaften des faserverstärkten Kraftfahrzeug-Sichtbauteils an der lackierfähigen Oberfläche statt, die durch weitere Lagen möglicherweise verursacht werden könnten. Somit kann gewährleistet werden, dass die komplette lackierfähige Oberfläche elektrostatisch aufgeladen werden kann und sich damit zum Lackieren eignet.In a further embodiment, it can be provided that the electrically conductive layer is arranged directly under the cover layer. In this way, there is no significant attenuation of the electrostatic properties of the fiber-reinforced automotive viewing component on the paintable surface, which could possibly be caused by further layers. Thus, it can be ensured that the complete paintable surface can be electrostatically charged and thus suitable for painting.
In einer weiteren möglichen Ausgestaltung des Kraftfahrzeug-Sichtbauteils kann die elektrisch leitende Schicht einen elektrischen Anschluss bzw. elektrischen Kontakt aufweisen. Auf diese Weise lässt sich von außen ein elektrisches Potenzial an der elektrisch leitenden Schicht anlegen, welche wiederum zu einer elektrostatischen Aufladung der lackierfähigen und zu lackierenden Oberfläche bedingt. Auf diese Weise lässt sich der Farbnebel zuverlässig auf den zu lackierenden Bereich lenken und eine genaue Einstellung des Prozesses ermöglichen.In a further possible embodiment of the motor vehicle viewing component, the electrically conductive layer may have an electrical connection or electrical contact. In this way, an electrical potential can be applied to the electrically conductive layer from the outside, which in turn results in an electrostatic charging of the paintable surface to be painted. In this way, the paint mist can be reliably directed to the area to be painted and allow a precise adjustment of the process.
In einer weiterführenden Ausgestaltung des faserverstärkten Kraftfahrzeug-Sichtbauteils kann vorgesehen sein, dass wenigstens eine Lage aus einem faserverstärkten Kunststoff mit Gewebe, Gelege, Geflecht, Gestrick, Gewirk, bevorzugt einem Monofilamentgewirk, oder Vlies, bevorzugt aus Polyesterfasern, Glasfasern, Aramidfasern, Kohlefasern oder Naturfasern, oder aus einer Kombination aus den vorgenannten bestehen bzw. besteht. Ein entsprechendes faserverstärktes Kraftfahrzeug-Sichtbauteil lässt sich gut durch Laminierprozesse herstellen.In a further embodiment of the fiber-reinforced motor vehicle viewing component, it can be provided that at least one layer of fiber-reinforced plastic with woven, scrim, braid, knitted fabric, knitted fabric, preferably a monofilament knit, or nonwoven, preferably of polyester fibers, glass fibers, aramid fibers, carbon fibers or natural fibers , or consists of a combination of the above. A corresponding fiber-reinforced motor vehicle vision component can be produced well by lamination processes.
Ein erster unabhängiger Gegenstand der vorliegenden Erfindung betrifft ein Kraftfahrzeug, das wenigstens ein Kraftfahrzeug-Sichtbauteil nach einem der vorangegangenen Ansprüche aufweist. Ein entsprechend ausgerüstetes Kraftfahrzeug lässt sich aufgrund der preiswerteren Herstellbarkeit eines entsprechenden Kraftfahrzeug-Sichtbauteils kostengünstiger herstellen als ein Kraftfahrzeug, bei dem ein herkömmliches faserverstärktes Kraftfahrzeug-Sichtbauteil verbaut ist, das mit einem Leitprimer versehen werden muss.A first independent subject matter of the present invention relates to a motor vehicle having at least one automotive viewing component according to one of the preceding claims. A suitably equipped motor vehicle can be produced more cost-effectively than a motor vehicle in which a conventional fiber-reinforced motor vehicle vision component is installed, which must be provided with a Leitprimer due to the cheaper manufacturability of a corresponding motor vehicle vision component.
In einer möglichen weiterführenden Ausgestaltung der Erfindung kann das Kraftfahrzeug-Sichtbauteil mit anschliessenden Karosseriebauteilen elektrisch leitend verbunden sein. Somit kann an das Kraftfahrzeug-Sichtbauteil ein elektrisches Potential angelegt werden.In a possible further embodiment of the invention, the motor vehicle viewing component can be electrically connected to subsequent body components. Thus, an electrical potential can be applied to the motor vehicle viewing component.
Ein weiterer unabhängiger Gegenstand der vorliegenden Erfindung betrifft ein Verfahren zum Herstellen eines Kraftfahrzeugs, wobei wenigstens ein Kraftfahrzeug-Sichtbauteil nach einem der vorangegangenen Ansprüche verbaut wird.A further independent subject matter of the present invention relates to a method for producing a motor vehicle, wherein at least one motor vehicle vision component according to one of the preceding claims is installed.
In einer ersten möglichen Weiterbildung des Verfahrens kann vorgesehen sein, dass das Kraftfahrzeug-Sichtbauteil lackiert wird. Das Lackieren des Kraftfahrzeug-Sichtbauteils kann vor dem Verbauen im restlichen Kraftfahrzeug passieren oder danach. Insbesondere kann das faserverstärkte Kraftfahrzeug-Sichtbauteil mit seiner elektrisch leitenden Lage eine Leitverbindung mit dem Rest der Karosserie herstellen, sodass dieses gleichmäßig lackiert werden kann.In a first possible development of the method can be provided that the motor vehicle viewing component is painted. The painting of the motor vehicle vision component can happen before obstructing the rest of the motor vehicle or thereafter. In particular, the fiber-reinforced motor vehicle viewing component with its electrically conductive layer can make a conductive connection with the rest of the body so that it can be painted evenly.
In einer weiteren möglichen Ausgestaltung des erfindungsgemäßen Verfahrens kann vorgesehen sein, dass ein Lackierroboter das Kraftfahrzeug-Sichtbauteil anhand des leitenden Vlieses erkennt. Das entsprechende Kraftfahrzeug-Sichtbauteil kann dann zuverlässig lackiert werden.In a further possible embodiment of the method according to the invention, provision can be made for a painting robot to recognize the motor vehicle vision component on the basis of the conductive fleece. The corresponding motor vehicle vision component can then be painted reliably.
