Abstract

A method for bonding a thermoplastic material (10) with a fibre-reinforced material (11) involves welding the two components together. An independent claim is included for a device comprising materials (10) and (11) bonded together by this method.

Description

Die Erfindung betrifft ein Verfahren zum Verbinden eines thermoplastischen Materials mit einem Faserverbundmaterial. Des Weiteren betrifft die Erfindung eine Vorrichtung umfassend thermoplastisches Material und Faserverbundmaterial.The The invention relates to a method for joining a thermoplastic Material with a fiber composite material. Furthermore it concerns the invention a device comprising thermoplastic material and fiber composite material.

Insbesondere im Flugzeugbau werden häufig thermoplastische Materialien mit Faserverbundmaterialien mittels einer mechanischen Befestigung, beispielsweise mittels Schrauben, oder durch Kleben befestigt. Beispielsweise werden häufig Kunststoffhalter, die thermoplastisches Material aufweisen, an Bauteilen, wie beispielsweise einer Seitenverkleidung oder einem Hatrack-Kasten, die Faserverbundmaterial aufweisen, innerhalb eines druckbelüfteten Bereichs beispielsweise innerhalb eines Kabinenbereiches eines Flugzeuges, miteinander befestigt.Especially in aircraft are often thermoplastic materials with fiber composite materials by means of a mechanical attachment, for example secured by screws or by gluing. For example often plastic holder, the thermoplastic material have on components such as a side panel or a hatrack box having fiber composite material within a pressurized area, for example within a cabin area of an aircraft, fastened together.

Das Kleben von Kunststoffhaltern, die thermoplastisches Material aufweisen, an Bauteilen, die Faserverbundmaterial aufweisen, erfordert eine sehr aufwendige Vorbehandlung der Klebeflächen der Kunststoffhalter. Die Flächen müssen zunächst aufgeraut und danach mit einem Primer vorbehandelt werden. Erst nach dieser Vorbehandlung können die Kunststoffhalter mit den Bauteilen verklebt werden. Dann muss eine gewisse Zeitdauer gewartet werden, in der Regel 5 bis 8 Stunden, bis der Klebstoff ausgehärtet ist und die notwendige Anfangshaftfestigkeit aufweist. Häufig werden auch Klebstoffe verwendet, die warmaushärtend sind. Bei einer Verwendung derartiger Klebstoffe müssen die miteinander zu verbindenden Kunststoffhalter und Bauteile bis zu 48 Stunden in einem Ofen ausgehärtet werden. Das Klebeverfahren ist also sehr aufwendig und zeitintensiv. Des Weiteren weisen die Klebstoffe gesundheitsgefährdende Inhaltsstoffe auf.The Bonding plastic holders comprising thermoplastic material, on components comprising fiber composite material requires a very elaborate pretreatment of the adhesive surfaces of the plastic holder. The surfaces must first be roughened and then pretreated with a primer. Only after this Pretreatment can be the plastic holder with the components be glued. Then a certain amount of time has to be waited in usually 5 to 8 hours, until the adhesive hardens is and has the necessary initial strength. Often also adhesives are used, which are thermosetting. When using such adhesives must be with each other To be connected plastic holder and components up to 48 hours cured in an oven. The bonding process is So very expensive and time consuming. Furthermore, the adhesives have harmful ingredients.

This is for the entire manufacturing process disadvantageous.

Eine resultierende Schichtenfolge im Verbindungsbereich ist schematisch in 2 dargestellt. Das thermoplastische Material 10 ist mit dem Faserverbundmaterial 11 verschweißt. In dieser Ausführungsform ist das Faserverbundmaterial 11 auf einer Wabenstruktur 12, insbesondere auf einer Nomexwabe aufgebracht.

Der mikroskopische Ablauf des Verbindungsprozesses kann möglicherweise, wie folgt, beschrieben werden.Of the microscopic course of the connection process may possibly as follows.

Während des Schweißens geht die Oberfläche des thermoplastischen Materials in eine zähflüssige Phase über, die oberhalb des Glasübergangsbereichs und unterhalb des Schmelzpunktes liegt. Das heißt, das thermoplastische Material wird lediglich angeschmolzen. Gleichzeitig wird die Oberfläche des Faserverbundmaterials erwärmt und geht eine quasi-chemische Verbindung mit der zähflüssigen Phase des thermoplastischen Materials ein. Wenn das Faserverbundmaterial Harze, insbesondere Polyadditions- und/oder Polykondensationsharze, aufweist, gehen möglicherweise noch unausgehärtete Harze mit der zähflüssigen Phase des thermoplastischen Materials eine quasi-chemische Verbindung ein.While of welding goes the surface of the thermoplastic Material into a viscous phase, the above the glass transition area and below the Melting point is. That is, the thermoplastic material is only melted. At the same time the surface becomes of the fiber composite material heats up and goes a quasi-chemical Compound with the viscous phase of the thermoplastic Materials. When the fiber composite resins, in particular Polyaddition and / or polycondensation, has, go possibly still unhardened resins with the viscous phase of the thermoplastic material a quasi-chemical compound.

Des Weiteren könnte die Verbindung dadurch zu Stande kommen, dass das zähflüssige thermoplastische Material des Halters durch Mikroporen des Faserverbundmaterial hindurchgezogen wird, so dass das thermoplastische Material in das Faserverbundmaterial hineingreift und so die Verbindung erzeugt. Das zäh-flüssige thermoplastische Material könnte des Weiteren so in das Faserverbundmaterial hinein- und durch das Faserverbundmaterial hindurchgezogen werden, dass es auf der von dem thermoplastischen Material abgewandten Seite des Faserverbundmaterials eine Verankerung bildet und so die Verbindung erzeugt. Die zähflüssige Phase des thermoplastischen Materials könnte insbesondere dann durch das Faserverbundmaterial hindurchgezogen werden, wenn das Faserverbundmaterial auf einer Wabenstruktur, wie beispielsweise in 2 gezeigt, aufgebracht ist. Auf Grund der Porosität des Faserverbundmaterials könnte es zu einer Kapillarwirkung in Richtung der Wabenstruktur kommen, die zumindest stellenweise zu einem Hineinziehen des zähflüssigen thermoplastischen Materials in das Faserverbundmaterial führen kann.Furthermore, the bond could be made by pulling the viscous thermoplastic material of the holder through micropores of the fiber composite material so that the thermoplastic material engages the fiber composite material to form the connection. The tough liquid thermoplastic material could further be drawn into the fiber composite material and pulled through the fiber composite material to anchor on the side of the fiber composite material remote from the thermoplastic material to form the bond. The viscous phase of the thermoplastic material could be pulled through the fiber composite material, in particular, when the fiber composite material is applied to a honeycomb structure, such as in FIG 2 shown is applied. Due to the porosity of the fiber composite material, there could be a capillary action in the direction of the honeycomb structure, which can lead at least in places to pulling the viscous thermoplastic material into the fiber composite material.

Im Folgenden werden Beispiele des erfindungsgemäßen Verfahrens zum Verbinden eines thermoplastischen Materials mit einem Faserverbundmaterial beschrieben.in the The following are examples of the invention Method of bonding a thermoplastic material to a Fiber composite described.

Then the holder by means of the rotating and lifting unit 2 and the holder holder 4 pressed on the GRP laminate and rotated relative to the GRP laminate to generate heat of movement and to connect the GRP laminate with the holder.

Der Druck, der während des Schweißprozesses zwischen dem thermoplastischen Material und dem FVK-Material wirkt, beträgt in diesem Beispiel 0,5, 1,0 und 1,5 bar. Für jeden dieser Drücke wurde in diesem Beispiel erfindungsgemäß eine Verbindung zwischen dem Halter, der das thermoplastische Material aufweist, und dem FVK-Material erzeugt. Während des Schweißprozesses wird in diesem Ausführungsbeispiel der Halter, der das thermoplastische Material aufweist, relativ zu dem FVK-Material mit einer Kreisfrequenz von 120 Hz gedreht. Die Schweißtiefe beträgt in diesem Ausführungsbeispiel 0,35 mm. In diesem Ausführungsbeispiel wurde der Schweißprozess mittels der Schweißtiefe geregelt, das heißt, der Schweißprozess wurde beendet, sobald die vorgegebene Schweißtiefe erreicht worden ist.Of the Pressure between during the welding process the thermoplastic material and the FRP material acts is 0.5, 1.0 and 1.5 bar in this example. For each of these Pressures in this example according to the invention a Connection between the holder, the thermoplastic material and generates the FRP material.
