Description
Die Erfindung betrifft ein kohlefaserverstärktes Bauteil zur Verbindung mit einem metallischen Verbindungselement, umfassend eine Durchgangsöffnung zur Aufnahme des metallischen Verbindungselementes sowie ein Fahrzeug.The invention relates to a carbon fiber reinforced component for connection to a metallic connecting element, comprising a through opening for receiving the metallic connecting element, and to a vehicle.
Im Zuge von Leichtbaubestrebungen werden in Kraftfahrzeugen kohlefaserverstärkte Verbundmaterialien eingesetzt, die sich durch eine hohe elektrische Leitfähigkeit auszeichnen. Um ein kohlefaserverstärktes Bauteil an dem Kraftfahrzeug zu befestigen, ist an dem kohlefaserverstärkten Bauteil ein Krafteinleitungspunkt erforderlich. Dazu werden metallische Komponenten mit einem metrischen Gewinde verwendet. Metalle und offene Carbonfasern in Kontakt in einem Nassbereich führen zu einer starken Kontaktkorrosion der Metalle, so dass eine Isolation des Metalls gegen das kohlefaserverstärkten Bauteil notwendig ist.As part of lightweight construction efforts, carbon fiber reinforced composite materials are used in motor vehicles, which are characterized by high electrical conductivity. In order to attach a carbon fiber reinforced component to the motor vehicle, a force introduction point is required on the carbon fiber reinforced component. Metallic components with a metric thread are used for this purpose. Metals and open carbon fibers in contact in a wet area lead to severe contact corrosion of the metals, so that the metal must be insulated from the carbon fiber reinforced component.

Die Aufgabe wird mit dem Gegenstand des Patentanspruchs 1 bzw. 4 gelöst.The problem is solved with the subject matter of
Bei dem Eingangs erläuterten kohlefaserverstärkten Bauteil zur Verbindung mit einem metallischen Verbindungselement, umfassend eine Durchgangsöffnung zur Aufnahme des metallischen Verbindungselementes, besteht das Bauteil aus mehreren übereinanderliegenden kohlefaserverstärkten Schichten, wobei zwischen jeweils zwei direkt übereinanderliegenden kohlefaserverstärkten Schichten partiell im Bereich der Durchgangsöffnung, diese vollständig umschließend, eine glasfaserverstärkte Schicht angeordnet ist, welche die kohlefaserverstärkten Schichten in Richtung der Durchgangsöffnung überragt und radial in die Durchgangsöffnung hineinragt. Unter kohlefaserverstärkten oder glasfaserverstärkten Schichten sind insbesondere Kohlenstofffaserverstärkte Kunststoffe (CFK), beziehungsweise Glasfaserverstärkte Kunststoffe (GFK) zu verstehen. Im Bereich des in die Durchgangsöffnung hineingreifenden metallischen Verbindungselementes herum liegen nur elektrisch isolierende Glasfasern, Polymer und gegebenenfalls Klebstoff der glasfaserverstärkten Schichten. Das metallische Verbindungselement ist somit gegenüber den Kohlestofffasern der kohlefaserverstärkten Schichten isoliert, obwohl Kohlenstofffasern der kohlefaserverstärkten Schichten an der Durchgangsöffnung freiliegen. Dadurch entfallen Instandhaltungskosten beim Verbau in einer Baueinheit. Ein Funktionsausfall auf Grund von Kontaktkorrosion wird somit zuverlässig vermieden.In the carbon fiber reinforced component explained at the beginning for connection to a metallic connecting element, comprising a through-opening for receiving the metallic connecting element, the component consists of several carbon fiber reinforced layers lying on top of each other, with a glass fiber reinforced layer being arranged between each two carbon fiber reinforced layers lying directly on top of each other, partially in the area of the through-opening, completely enclosing it, which projects beyond the carbon fiber reinforced layers in the direction of the through-opening and projects radially into the through-opening. Carbon fiber reinforced or glass fiber reinforced layers are to be understood in particular as carbon fiber reinforced plastics (CFRP) or glass fiber reinforced plastics (GFRP). In the area of the metallic connecting element that extends into the through-opening, there are only electrically insulating glass fibers, polymer and, if applicable, adhesive of the glass fiber reinforced layers. The metallic connecting element is thus insulated from the carbon fibers of the carbon fiber reinforced layers, although carbon fibers of the carbon fiber reinforced layers are exposed at the through-opening. This eliminates maintenance costs when installed in a structural unit. Functional failure due to contact corrosion is thus reliably avoided.
Die glasfaserverstärkte Schicht ist in mindestens eine der direkt übereinanderliegenden kohlenfaserverstärkten Schichten integriert und bildet einen Übergangsbereich, aus welchem die glasfaserverstärkte Schicht radial in die Durchgangöffnung hineinragt. Die Integration der glasfaserverstärkten Schicht in die kohlefaserverstärkte Schicht bewirkt eine zuverlässige, feste Verbindung zwischen den beiden Schichten, durch welche sichergestellt wird, dass immer nur die aus der glasfaserverstärkten Schicht herausragenden Glasfasern mit dem metallischen Verbindungselement in Kontakt treten können.The glass fiber reinforced layer is integrated into at least one of the carbon fiber reinforced layers lying directly on top of one another and forms a transition area from which the glass fiber reinforced layer protrudes radially into the through-opening. The integration of the glass fiber reinforced layer into the carbon fiber reinforced layer creates a reliable, solid connection between the two layers, which ensures that only the glass fibers protruding from the glass fiber reinforced layer can come into contact with the metallic connecting element.
Es ist auch möglich, dass die GFK-Schicht und die CFK-Schicht im Übergangsbereich zwischen GFK und CFK in mehrere Lagen oder Schichten aufgefächert sind, und dass jede GFK-Schicht oder -Lage in korrespondierenden CFK-Schichten oder -Lagen integriert ist. Im Übergangsbereich liegt quasi eine Sandwichstruktur aus mehreren CFK- und GFK-Lagen oder -Schichten vor.It is also possible that the GRP layer and the CFRP layer are divided into several layers or plies in the transition area between GRP and CFRP, and that each GRP layer or ply is integrated into corresponding CFRP layers or plies. In the transition area, there is essentially a sandwich structure made up of several CFRP and GRP layers or plies.
In einer Ausgestaltung weisen die glasfaserverstärkten Schichten zueinander einen Winkelversatz in ihrer Faserorientierung auf. Dadurch kann in einem einfachen Auflaminierprozess eine besonders stabile Kunststoffstruktur geschaffen werden.In one embodiment, the glass fiber reinforced layers have an angular offset in their fiber orientation. This allows a particularly stable plastic structure to be created in a simple lamination process.
In einer Variante ist die die Durchgangsöffnung umschließende glasfaserverstärkte Schicht als runde oder rechteckige Platte ausgebildet. Durch das Einfügen von runden bzw. rechteckigen glasfaserverstärkten Platten zwischen die kohlenstoffverstärkten Schichten lässt sich die Stabilität der so geschaffenen Struktur beeinflussen und dem jeweiligen Anwendungsfall anpassen.In one variant, the glass fiber reinforced layer surrounding the through hole is designed as a round or rectangular plate. By inserting round or rectangular glass fiber reinforced plates between the carbon reinforced layers, the stability of the structure created in this way can be influenced and adapted to the respective application.
In einer erfindungsgemäßen Ausführungsform ist innerhalb der glasfaserverstärkten Schicht zwischen dem Übergangsbereich und der Durchgangsöffnung eine Feuchtigkeitsableitbohrung ausgebildet. Da sich auf dem kohlefaserverstärkten Schichten Spritzwasser ablagern kann, dient die Feuchtigkeitsableitbohrung dazu, dieses von dem metallischen Verbundelement wegzuleiten. Dies stellt einen zusätzlichen Korrosionsschutz dar.In an embodiment according to the invention, a moisture drainage hole is formed within the glass fiber reinforced layer between the transition area and the through-opening. Since splash water can accumulate on the carbon fiber reinforced layer, the moisture drainage hole serves to drain this away from the metallic composite element. This provides additional corrosion protection.
Ein weiterer Aspekt der Erfindung betrifft ein Fahrzeug, bei welchem ein metallisches Karosseriebauteil mit einem kohlefaserverstärkten Bauteil mittels einem metallischen Verbindungselement mechanisch verbunden ist, wobei das Karosseriebauteil und das kohlefaserverstärkte Bauteil übereinanderliegende Durchgangsöffnungen aufweisen, in welche das metallische Verbindungselement kraftschlüssig und/oder stoffschlüssig eingeführt ist, wobei das kohlefaserverstärkte Bauteil nach mindestens einem der in dieser Schutzrechtsanmeldung beschriebenen Merkmal ausgebildet ist. Durch die Unterbindung von Kontaktkorrosion in den der Witterung ausgesetzten, insbesondere spritzwassergefährdeten, Bereichen des Fahrzeuges, können kostengünstige metallische Materialen eingesetzt werden.A further aspect of the invention relates to a vehicle in which a metallic body component is mechanically connected to a carbon fiber reinforced component by means of a metallic connecting element, wherein the body component and the carbon fiber reinforced component have through holes lying one above the other into which the metallic connecting element is inserted in a force-fitting and/or material-fitting manner, wherein the carbon fiber reinforced component is designed according to at least one of the features described in this patent application. By preventing contact corrosion in the areas of the vehicle exposed to the weather, in particular those at risk of splashing water, cost-effective metallic materials can be used.
Es ist von Vorteil, wenn das metallische Karosseriebauteil aus Stahl oder Aluminium besteht und das an der Fahrzeugkarosserie anzubindende Bauteil eine Glasfaserverstärkung und Kohlefaserverstärkung aufweist.It is advantageous if the metallic body component is made of steel or aluminum and the component to be connected to the vehicle body has glass fiber reinforcement and carbon fiber reinforcement.
In einer weiteren Ausgestaltung sind das aus Metall bestehende Karosseriebauteil als Querträger des Fahrzeug-Front Ends und das kohlefaserverstärkte Bauteil als Spoiler des Fahrzeuges ausgebildet.In a further embodiment, the metal body component is designed as a cross member of the vehicle's front end and the carbon fiber reinforced component is designed as a spoiler of the vehicle.
