Description

Verbundteil composite part
Die Erfindung betrifft ein Verbundteil aus mindestens einer Primärkomponente und mit dieser (diesen) unlösbar verbunden, mindestens einer Sekundärkomponente, welche Komponenten miteinander im Wesentlichen unlösbar verbunden sind.The invention relates to a composite part composed of at least one primary component and permanently connected to it, at least one secondary component, which components are essentially permanently connected to one another.
Monolithische Teile bzw. Teile, .die aus einem Werkstoff gefertigt sind, weisen zumeist ein bestimmtes, nicht wesentlich veränderbares Eigenschaftsprofil auf, wobei für einen geplanten Verwendungszweck einerseits günstige, andererseits aber auch nachteilige Einzeleigenschaften vorliegen. Durch konstruktive Maßnahmen, die oft durchaus hohe Aufwendungen erfordern, können zwar einzelne ungünstige Teileigenschaften abgeschwächt oder ausgeschaltet werden, ein vorteilhaft abgestimmtes Gesamteigenschaftsprofil eines Teiles im Hinblick auf die technischen und wirtschaftlichen Anforderungen an dieses ist in der Regel nicht erstellbar.Monolithic parts or parts that are made from one material usually have a specific property profile that cannot be changed significantly, with favorable, but also disadvantageous individual properties for a planned use. By constructive measures, which often require a lot of effort, individual unfavorable part properties can be weakened or switched off, an advantageously coordinated overall property profile of a part with regard to the technical and economic requirements for this is generally not feasible.
Von einem Bauteil in Kombination gewünschte Einzeleigenschaften, wie zum Beispiel niedrige Wärmeleitung, hohe Schalldämmung und Schwingungsdämpfung, gezielte bzw. einstellbare Energieaufnahme bei der Verformung, Verbindbarkeit und Stabilität, Lösungs- sowie Korrosionsverhalten und dergleichen, können weder durch Werkstoffwahl noch durch bauliche Maßnahmen in wirtschaftlicher Weise realisiert werden, so dass in zunehmendem Maße in der modernen Technik Verbundteile eingesetzt werden.Individual properties of a component in combination, such as low heat conduction, high sound insulation and vibration damping, targeted or adjustable energy absorption during deformation, connectivity and stability, solution and corrosion behavior and the like, cannot be achieved economically either through the choice of materials or through structural measures be realized, so that composite parts are increasingly used in modern technology.
Der Erfindung liegt nun die Aufgabe zugrunde, einen Verbundteil zu schaffen, welcher einfach aufbaubar ist, eine Vielzahl an Einzeleigenschaftskombinationen erstellen läßt und kostengünstig herstellbar ist.The invention is based on the object of creating a composite part which is simple to set up, allows a large number of individual property combinations to be created and can be produced inexpensively.
Diese Aufgabe wird bei einem Verbundteil der eingangs genannten Art dadurch gelöst, dass die Primärkomponente(n) aus einem Leichtmetall oder einer Leichtmetall-Legierung mit einer Dichte von kleiner als 4,5 kg/dm3 besteht (bestehen) und die Sekundärkomponente(n) aus einem nichtmetallischen Werkstoff oder einem Gemisch aus nichtmetallischem und metallischem Werkstoff gebildet ist (sind) und die mechanische Eigenschaft der Komponenten zur Erstellung der Eigenschaft des Verbundteiles aufeinander abgestimmt ist.This object is achieved in the case of a composite part of the type mentioned at the outset in that the primary component (s) consists of a light metal or a light metal alloy with a density of less than 4.5 kg / dm 3 and the secondary component (s) is formed from a non-metallic material or a mixture of non-metallic and metallic material (Are) and the mechanical property of the components to create the property of the composite part is coordinated.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass Teile mit einem auf deren Verwendung genau abgestimmten Eigenschaftsprofil herstellbar sind. Dabei ist der Einsatz von Leichtmetall oder von einer Leichtmetall-Legierung erfindungsgemäß wichtig, weil einerseits eine Formung dieses Werkstoffes zu vielfältigen geometrischen Ausführungen der Primärkomponente günstig erfolgen kann und andererseits eine Abstimmbarkeit mit nichtmetallischen Werkstoffen ein breites Spektrum eines Eigenschaftsprofiles des Verbundteiles ermöglicht. Auch die gute Be- und Verarbeitbarkeit, eine hohe Korrosionsbeständigkeit gegen Säuren, eine vielfältige Beschichtungsmöglichkeit, sowie ein geringes Teilgewicht sind Vorteile des Einsatzes von Leichtmetall.The advantages achieved by the invention are, in particular, that parts can be produced with a property profile that is precisely tailored to their use. Here, the use of light metal or a light metal alloy is important according to the invention because, on the one hand, this material can be shaped cheaply into diverse geometric designs of the primary component and, on the other hand, compatibility with non-metallic materials enables a broad spectrum of a property profile of the composite part. The good workability and workability, high corrosion resistance to acids, a wide range of coating options and a low part weight are advantages of using light metal.
Zur Erstellung einer unlösbaren Verbindung zwischen den Komponenten kann eine Behandlung der Metall-Teiloberfläche oder das Aufbringen eines Haft-Vermittlers vorgesehen sein, wobei ein Verbinden oder ein Ein- bzw. Umformen und dergleichen mit nichtmetaliischem Werkstoff durch Spritzgießen, Thermoformen, Extrudieren und anderen Verfahren erzielbar ist.To create an inseparable connection between the components, a treatment of the metal partial surface or the application of an adhesion promoter can be provided, whereby a connection or a molding or forming and the like with non-metallic material can be achieved by injection molding, thermoforming, extrusion and other processes is.
Weil nun die Sekundärkomponente auch eine stützende Funktion haben kann, ist es gegebenenfalls auch möglich, den Querschnitt der Primärkomponente besonders zu formen und/oder zu verringern.Because the secondary component can now also have a supporting function, it may also be possible to particularly shape and / or reduce the cross section of the primary component.
Gemäß der Erfindung kann es von Vorteil sein, wenn der nichtmetallische Werkstoffteil der Sekundärkomponente Fasern enthält. Dadurch ist es möglich, besondere oder richtungsabhängige Eigenschaften der Nichtmetall-Komponente vorzusehen.According to the invention, it can be advantageous if the non-metallic material part of the secondary component contains fibers. This makes it possible to provide special or direction-dependent properties of the non-metal component.
In einer Weiterbildung der Erfindung kann von besonderem Vorteil sein, wenn die Sekundärkomponenten zumindest teilweise aus Holz, einem Holzderivat oder einem Material von Einjahrespflanzen gebildet ist. Dabei können nicht nur eine Erweiterung des Einsatzgebietes von Verbundteilen, sondern auch eine hohe Wirtschaftlichkeit der Herstellung bzw. vergleichsweise niedrige Teilkosten erreicht werden.In a further development of the invention, it can be particularly advantageous if the secondary components are formed at least partially from wood, a wood derivative or a material from annual plants. Not only can the area of application of composite parts be expanded, but also a high level of economy manufacturing or comparatively low part costs can be achieved.
Extrem leichte Verbundteile mit hoher Wärmedämmwirkung sind herstellbar, wenn die Sekundärkomponente homogen schaumförmig ausgebildet ist. Eine Isotropie der Hohlräume im nichtmetallischen Teil ist einerseits für eine flächige Stützung der metallischen Primärkomponente für ein sicheres Erreichen von gewünschten mechanischen Eigenschaften und andererseits für ein gleichmäßig verteiltes spezifisches Gewicht des Teiles wichtig.Extremely light composite parts with a high thermal insulation effect can be produced if the secondary component is homogeneously foam-shaped. An isotropy of the cavities in the non-metallic part is important on the one hand for a flat support of the metallic primary component for a reliable achievement of the desired mechanical properties and on the other hand for an evenly distributed specific weight of the part.
Wenn, wie gemäß der Erfindung vorgesehen sein kann, der nichtmetallische Werkstoffteil der Sekundärkomponente thermoplastischen Kunststoff enthält, ist eine günstige Formgebung bei erhöhter Termperatur und unmittelbar nach einer zumindest teilweisen Abkühlung ein Einsatz des Verbundteiles belastungsentsprechend möglich.If, as can be provided according to the invention, the non-metallic material part of the secondary component contains thermoplastic material, a favorable shaping with increased temperature and immediately after an at least partial cooling can be used in accordance with the load.
Erfindungsgemäß ist es auch möglich, die metallische Komponente und die nichtmetallische Komponente getrennt herzustellen und anschließend zu verbinden, was produktionstechnisch Vorteile einschließen kann, wobei letztlich die Komponenten durch Kleben gefügt sind.According to the invention, it is also possible to produce the metallic component and the non-metallic component separately and then to connect them, which can include advantages in terms of production technology, the components ultimately being joined by adhesive bonding.
Wenn in Weiterbildung der Erfindung das Teil mittels Extrudierens, vorzugsweise bei erhöhter Temperatur hergestellt ist, weist dieses höchste geometrische Genauigkeit in Längserstreckung auf und ist vorteilhaft für Lang-Verbundteile mit besonderem Eigenschaftsprofil unmittelbar nach Abkühlung einsetzbar bzw. verwendbar.If, in a further development of the invention, the part is produced by extrusion, preferably at elevated temperature, it has the highest geometrical accuracy in the longitudinal direction and can advantageously be used or used for long composite parts with a special property profile immediately after cooling.
Wenn, wie vorgesehen sein kann, erfindungsgemäß die metallische Primärkomponente die zumindest teilweise aus nichtmetaliischem Werkstoff gebildete Sekundärkomponente im Querschnitt allseitig umschließt, ist einerseits ein Schutz des nichtmetallischen Teiles vor UV-Strahlung und Oxidation bzw. Verwitterung möglich, andererseits kann eine besonders gute mechanische Nutzung des Leichtmetallquerschnittes erreicht werden.If, as can be provided, according to the invention the metallic primary component encloses the cross-section of the secondary component formed at least partially from non-metallic material, on the one hand protection of the non-metallic part against UV radiation and oxidation or weathering is possible, on the other hand a particularly good mechanical use of the Light metal cross section can be achieved.
Bei höchster Korrosionsbeanspruchung, oder zum Erreichen von besonders ausgeprägter Schalldämmung oder Schwingungsdämpfung sowie Stützung von Abdeckungen kann es günstig sein, wenn die metallische Primärkomponente(n) flächig ausgebildet und zumindest einseitig mit einer Sekundärkomponente verbunden ist (sind).With the highest corrosion stress, or to achieve particularly pronounced sound insulation or vibration damping as well as support of covers, it can be favorable if the metallic primary component (s) is flat and is (are) connected at least on one side to a secondary component.
Für Kühlmedien-Leistungen, und dergleichen Teile kann es günstig und hoch wirtschaftlich sein, wenn eine metallische Primärkomponente rohrförmig ausgebildet und außenseitig durch eine im Wesentlichen aus einem nichtmetallischen Werkstoff bestehenden Sekundärkomponente umhüllt ist.For cooling media services and similar parts, it can be inexpensive and highly economical if a metallic primary component is tubular and is externally encased by a secondary component consisting essentially of a non-metallic material.
Dabei können Einzelteile zu langen Leitungen, beispielsweise durch Kleben verbunden sein und temperaturstabile Systeme bilden. Individual parts can be connected to form long lines, for example by gluing, and form temperature-stable systems.
