Description

Die Erfindung betrifft ein Verfahren zur Verbindung zweier Karosserieteile eines Kraftfahrzeugs, von denen wenigstens eines aus einem Faserverbundwerkstoff besteht, nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to a method for connecting two body parts a motor vehicle, of which at least one of a fiber composite material consists, according to the closer defined in the preamble of claim 1 Art.

Ein gattungsgemäßes Verfahren ist aus dem allgemeinen Stand der Technik bekannt. Zur Abdichtung von Spalten zwischen zwei miteinander verbundenen Karosseriebauteilen wird meist ein Abdichtmaterial auf PVC-Basis verwendet, das hinsichtlich seiner Elastizität für diesen Zweck sehr gut geeignet ist, da es innerhalb sehr kurzer Zeit aufgetragen werden kann, was eine schnelle und kostengünstige Fertigung erlaubt. Zwar muss dieses Abdichtmaterial bei höheren Temperaturen von beispielsweise 80°C ausgehärtet werden, da die Abdichtung der Karosseriebauteile jedoch vor deren Lackierung erfolgt, die ihrerseits bereits eine Erwärmung der Karosseriebauteile mit sich bringt, ist diese Aushärtung im Wesentlichen kostenneutral durchführbar.One generic method is known from the general state of the art. For sealing of gaps between two interconnected body parts Usually a sealing material based on PVC is used, which in terms of its elasticity For this Purpose is very well suited as it applied within a very short time which allows fast and cost-effective production. Though This sealing material must be at higher temperatures, for example Be cured at 80 ° C, However, since the sealing of the body components before their painting takes place, which in turn already a warming of the body parts This is curing essentially cost-neutral feasible.

Wenn eines der Karosserieteile des Kraftfahrzeugs jedoch aus einem Faserverbundwerkstoff besteht, tritt zum Einen das Problem auf, dass ein auf PVC basierendes Abdichtmaterial nur äußerst schlecht auf dem Faserverbundwerkstoff haftet, und dass zum Anderen bei der Weiterverarbeitung dieser Faserverbundwerkstoffe üblicherweise kein Lackiervorgang mehr stattfindet, weshalb eine Wärmebehandlung zum Aushärten eines solchen Abdichtmaterials auf PVC-Basis nur mit einem äußerst großen Aufwand möglich wäre.If However, one of the body parts of the motor vehicle consists of a fiber composite material, On the one hand occurs the problem that a PVC-based sealing material only very bad adheres to the fiber composite material, and that on the other in the Further processing of these fiber composites usually no painting process takes place anymore, which is why a heat treatment for curing such a sealing material based on PVC only with great effort possible would.

Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren zur Verbindung zweier Karosserieteile eines Kraftfahrzeugs zu schaffen, von denen wenigstens eines aus einem Faserverbundwerkstoff besteht, mittels welchem eine sichere, zuverlässige und mit vertretbarem Aufwand durchführbare Abdichtung eines Spalts zwischen den beiden Karosserieteilen durchgeführt werden kann.It is therefore an object of the present invention, a method for To create a connection between two body parts of a motor vehicle at least one of which consists of a fiber composite material, by means of which a safe, reliable and with justifiable Effort feasible Sealing a gap between the two body parts are performed can.

Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention this Problem solved by the features mentioned in claim 1.

Vorteilhafterweise haftet der erfindungsgemäß verwendete Strukturkleber auch auf einem Faserverbundwerkstoff und härtet darüber hinaus bei Raumtemperatur aus. Zwar ist zur Aushärtung des Strukturklebers eine gewisse Zeit erforderlich, es kann jedoch auf eine zusätzliche Wärmeeinbringung verzichtet werden, so dass die erfindungsgemäße Lösung eine sehr einfache Fertigung ermöglicht.advantageously, adheres to the invention used Structural adhesive also on a fiber composite material and hardens beyond at room temperature. Although it is for curing the structural adhesive it may take some time, but it may be additional Heat input omitted be, so that the solution of the invention is a very simple production allows.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen. Nachfolgend sind Ausführungsbeispiele der Erfindung anhand der Zeichnung prinzipmäßig dargestellt.advantageous Refinements and developments of the invention will become apparent the dependent claims. Below are embodiments of the Invention shown in principle with reference to the drawing.

Dies zeigt:This shows:

1 eine Seitenansicht einer ersten Anwendung des erfindungsgemäßen Verfahrens; 1 a side view of a first application of the method according to the invention;

2 einen Schnitt durch eine zweite Anwendung des erfindungsgemäßen Verfahrens; und 2 a section through a second application of the method according to the invention; and

3 eine schematische Ansicht einer weiteren Anwendung des erfindungsgemäßen Verfahrens. 3 a schematic view of a further application of the method according to the invention.

In 1 ist eine Karosserie 1 eines Kraftfahrzeugs dargestellt, welche zwei Karosserieteile 2, 3 aufweist. Bei der Ausführungsform von 1 handelt es sich hierbei um einen Schweller 2a und eine Bodenstruktur 3a. Von den beiden Karosserieteilen 2 und 3 besteht wenigstens eines aus einem Faserverbundwerkstoff, im vorliegenden Ausführungsbeispiel die Bodenstruktur 3a. Vorzugsweise besteht das andere Karosserieteil 2, also der Schweller 2a, aus einem metallischen Werktoff, beispielsweise aus Aluminium oder aus Stahl. An wenigstens einer Verbindungsstelle 4 wird die Bodenstruktur 3a mit dem Schweller 2a verbunden bzw. an demselben angebracht, wozu an der Verbindungsstelle 4 ein Strukturkleber 5 zwischen die beiden Karosserieteile 2 und 3 eingebracht wird. Anschließend wird ein zwischen den beiden Karosserieteilen 2 und 3 vorhandener Spalt 6 abgedichtet, wozu ebenfalls der Strukturkleber 5 verwendet wird. Als Strukturkleber 5 wird vorzugsweise ein Zweikomponenten kleber verwendet, welcher in Form einer länglichen Dichtnaht am äußeren Bereich des Spalts 6 aufgebracht wird. Bei der Ausführungsform gemäß 1 überlappen sich die beiden Karosserieteile 2 und 3 um einen gewissen Betrag, was jedoch nicht unbedingt erforderlich ist, um den Spalt 6 zwischen denselben zu bilden.In 1 is a body 1 a motor vehicle shown which two body parts 2 . 3 having. In the embodiment of 1 this is a sill 2a and a soil structure 3a , From the two body parts 2 and 3 If at least one of a fiber composite material, in the present embodiment, the soil structure 3a , Preferably, the other body part 2 So the sill 2a , made of a metallic work fabric, for example aluminum or steel. At least one connection point 4 becomes the soil structure 3a with the sill 2a connected or attached to the same, including at the junction 4 a structural adhesive 5 between the two body parts 2 and 3 is introduced. Then one between the two body parts 2 and 3 existing gap 6 sealed, including the structural adhesive 5 is used. As a structural adhesive 5 Preferably, a two-component adhesive is used, which in the form of an elongated sealing seam at the outer region of the gap 6 is applied. In the embodiment according to 1 the two body parts overlap 2 and 3 by a certain amount, which is not essential to the gap 6 to form between them.

Bei der Ausführungsform gemäß 2 werden als Karosserieteile 2 und 3 eine Rohbaukarosse 2b und ein Dach 3b verwendet werden. Innerhalb des dabei nicht erkennbaren Spalts 6 befindet sich ebenfalls der Strukturkleber 5, der verwendet wird, um das bei dieser Ausführungsform aus dem Faserverbundwerkstoff bestehende Dach 3b mit der zum Beispiel aus einem Aluminiumwerkstoff bestehenden Rohbaukarosse 2b zu verkleben. Wiederum wird zum Abdichten des Spalts 6 der Strukturkleber 5 verwendet.In the embodiment according to 2 be as body parts 2 and 3 a body shell 2 B and a roof 3b be used. Within the unseen gap 6 is also the structural adhesive 5 which is used around the roof made of the fiber composite material in this embodiment 3b with the existing example of an aluminum material shell body 2 B to stick together. Again, to seal the gap 6 the structure adhesive 5 used.

Bei der Ausführungsform gemäß 3 wird ein Karosserieteil 3 eines Kraftfahrzeugs mittels des Strukturklebers 5 an zwei anderen Karosserieteilen 2 angebracht, wobei der dabei vorhandene Spalt 6 wiederum mittels einer länglichen Dichtnaht mit dem Strukturkleber 5 abgedichtet wird.In the embodiment according to 3 becomes a body part 3 a motor vehicle by means of structural adhesive 5 on two other body parts 2 attached, with the existing gap 6 again by means of an elongated sealing seam with the structural adhesive 5 is sealed.
