Zusammenfassend und mit anderen Worten dargestellt ergibt sich somit durch die Erfindung unter anderem ein Kombi-Schweißelement zum Schweißen von Fügepartnern aus duromeren und thermoplastischen Kunststoffen.In summary, in other words, the invention thus provides, inter alia, a combination welding element for welding joining partners of duromeric and thermoplastic plastics.
Bei der Herstellung der Fügepartner aus duromeren Faserverbundkunststoffen kann auf der späteren Fügefläche ein Schweißelement aufgebracht werden, bestehend aus einem Verbund aus Thermoplast, Isolator, Drahtgewebestruktur. Zwei Alternativen könnten anstelle der leitfähigen Komponente „Drahtgewebestruktur“ verwendet werden: 1. eine exotherm reagierende Schicht (genannt „Reactive multilayer system“, RMS), oder 2. ein induktiv anregbares Metallpulver. An den Positionen in einem Bauteil, an welchen dieses Schweißelement vor einer Infusion eingebracht wurde, besteht die Möglichkeit, thermoplastische Anbauteile bzw. solche mit einer thermoplastischen Außenschicht durch einen Schweißprozess anzubringen.In the production of the joining partners from duromer fiber composite plastics, a welding element can be applied to the later joining surface, consisting of a composite of thermoplastic, insulator, wire mesh structure. Two alternatives could be used instead of the conductive component "wire mesh structure": 1. an exothermic reactive layer (called "Reactive multilayer system", RMS), or 2. an inductively energizable metal powder. At the positions in a component to which this welding element has been introduced before an infusion, it is possible to attach thermoplastic components or those with a thermoplastic outer layer by means of a welding process.
Das Schweißelement kann aus einem Verbund einzelner Schichten bestehen. Diese Einheit kann vorkonfektioniert und auf eine Preform appliziert werden und im Infusionsprozess mit einem Duromerbauteil eine Verbindung eingehen. Basis für diese chemische Verbindung kann ein Film-Diffusions-Verfahren sein.The welding element may consist of a composite of individual layers. This unit can be pre-assembled and applied to a preform and connected in the infusion process with a Duromerbauteil. Basis for this chemical compound may be a film diffusion method.
Durch Verwendung dieses Schweißelements können Duromerbauteile hergestellt werden, die als Fügepartner zu anderen Verbundbauteilen dienen. Im Fügebereich kann eine heizbare Thermoplastschicht appliziert sein, die zwei Funktionen erfüllt: 1. Die Fügefläche eignet sich für weitere Schweißaufgaben; 2. Die Fügefläche bietet die Möglichkeit zur Temperatureinbringung direkt und begrenzt auf der Fügefläche.By using this welding element Duromerbauteile can be produced, which serve as a joining partner to other composite components. In the joining area, a heatable thermoplastic layer can be applied that fulfills two functions: 1. The joining surface is suitable for further welding tasks; 2. The joining surface offers the possibility of temperature application directly and limited to the joining surface.
Der Prozessschritt „Assembly“ kann vereinfacht werden: Eine Positionierung des Schweißelements auf einer noch nicht formstabilen Preform kann vereinfacht mit reduzierter Präzision erfolgen, ohne dass eine Gesamtgenauigkeit einer späteren Baugruppe gefährdet ist. Beim anschließenden Fügen von Bauteilen sind nun beide Komponenten formstabil und können präzise gehandhabt und zueinander positioniert werden.The process step "Assembly" can be simplified: A positioning of the welding element on a not yet dimensionally stable preform can be simplified with reduced precision, without jeopardizing the overall accuracy of a later assembly. In the subsequent joining of components, both components are now dimensionally stable and can be handled precisely and positioned relative to one another.
Der Prozessschritt „Temperatureinbringung“ kann vereinfacht werden: Bei einem Widerstandsschweißen kann ein Prozessschritt eingespart werden, wie es z.B. beim nachträglichen Aufbringen eines Schweißelements nötig wäre. Ein Heizen der kompletten Fügepartner kann entfallen, wie es z.B. in einem Ofen oder Autoklav nötig wäre. Ein lokales Durchheizen der Fügebereiche durch Temperatureinbringung von außen kann entfallen, wie es z.B. in einer Presse nötig wäre.The process step "temperature introduction" can be simplified: In resistance welding, a process step can be saved, as e.g. would be necessary for the subsequent application of a welding element. Heating of the complete joining partner can be omitted, as it is e.g. would be necessary in an oven or autoclave. Local heating of the joining areas by external temperature application can be dispensed with, as is described, for example, in US Pat. would be necessary in a press.
Assemblyprozesse können von der Bauteilherstellung entkoppelt werden: Montagereihenfolge nicht mehr durch Herstellprozess festgelegt; Keine Steigerung der Komplexität des Vakuumaufbaus für eine Infiltration bei der Bauteilherstellung.Assembly processes can be decoupled from component production: Assembly sequence no longer determined by manufacturing process; No increase in the complexity of the vacuum structure for infiltration in component manufacturing.
Zusätzliches Merkmal bei der Bauvariante mit der Komponente „Drahtgewebestruktur“: Möglichkeit zum späteren Lösen der Verbindung, falls die elektrischen Anschlussstücke des Schweißelements nach dem Assemblyprozess am Bauteil verbleiben.Additional feature in the construction variant with the component "wire mesh structure": possibility for later release of the connection, if the electrical connection pieces of the welding element remain after the assembly process on the component.
Mit „kann“ sind insbesondere optionale Merkmale der Erfindung bezeichnet. Demzufolge gibt es jeweils ein Ausführungsbeispiel der Erfindung, das das jeweilige Merkmal oder die jeweiligen Merkmale aufweist.By "may" in particular optional features of the invention are referred to. Accordingly, there is an embodiment of the invention each having the respective feature or features.
Mit der Erfindung wird ein Herstellen einer Duroplast-Thermoplast-Verbindung vereinfacht. Ein Erwärmen kann gezielt lokal an einer Fügestelle erfolgen. Ein Durchwärmen eines Fügepartners ist nicht erforderlich. Ein nachträgliches Einbringen eines Heizelements ist nicht erforderlich. Eine Maßhaltigkeit kann verbessert werden. Eine Komplexität eines Vakuumaufbaus für eine Infiltration kann reduziert werden. Ein gesonderter Härtezyklus in einem Ofen kann entfallen. Eine Variabilität einer Montagereihenfolge kann erhöht werden. Eine Reparaturfähigkeit wird verbessert.With the invention, a production of a thermoset thermoplastic compound is simplified. Heating can be done locally at a joint. Soaking a joining partner is not required. Subsequent insertion of a heating element is not required. Dimensional accuracy can be improved.
