Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Faserverbundwerkstoffs mit metallischer Matrix.The invention relates to a method for producing a fiber composite material with a metallic matrix.

Es sind Faserverbundwerkstoffe aus Kunststoff bekannt, bei denen beispielsweise Glas-, Kohlenstoff- oder Aramidfasern in ein Kunstharz wie Epoxid-, Polyester- oder Vinylesterharz oder ein ähnliches Kunstharz eingebettet sind. Dabei bildet das Kunstharz'eine Matrix, welche die typischerweise in Form eines Geleges, Gewebes oder Geflechts angeordneten Fasern umhüllt und miteinander verbindet. Problematisch bei derartigen herkömmlichen Kunststoff-Faserverbundwerkstoffen ist der Umstand, dass sie im Schadensfall, etwa bei Fahrzeugen, wie Land-, Wasser- oder insbesondere Luftfahrzeugen brennbar und splitterbruchempfindlich mit scharfkantigen, spitzen Bruchstücken sind.There are fiber composites made of plastic, in which, for example, glass, carbon or aramid fibers are embedded in a synthetic resin such as epoxy, polyester or vinyl ester resin or a similar synthetic resin. In this case, the synthetic resin forms a matrix which encloses the fibers, which are typically arranged in the form of a fabric, woven fabric or braid, and connects them to one another. The problem with such conventional plastic fiber composites is the fact that they are flammable in the event of damage, such as vehicles, such as land, water or aircraft in particular splinter-break with sharp-edged, sharp fragments.

Zudem sind Verbundwerkstoffe mit metallischer Matrix bekannt (auch Metallmatrix-Verbundwerkstoffe genannt), die jedoch in der Regel technisch aufwendig herzustellen sind, da Ur- oder Formkörper verwendet werden, was zudem den Nachteil mit sich bringt, dass die geometrische Gestaltungsfreiheit des herzustellenden Halbzeuges oder Bauteils recht eingeschränkt ist. Des Weiteren sind die bisher verwendeten Metallmatrix-Verbundwerkstoffe meist schwer, was insbesondere in der Luft- und Raumfahrttechnik von Nachteil ist. Zudem weisen sie den Nachteil auf, dass keine kraftschlüssige Verbindung zwischen Fasern und Metall erzeugt wird.In addition, composites are known with metallic matrix (also called metal matrix composite materials), which are, however, usually technically complex to produce, since primitive or molded bodies are used, which also has the disadvantage that the geometric freedom of the semifinished product or component to be produced is quite limited. Furthermore, the metal matrix composite materials used hitherto are usually heavy, which is disadvantageous in particular in the aerospace industry. In addition, they have the disadvantage that no frictional connection between fibers and metal is generated.

Mit PVD/CVD-Verfahren können beispielsweise Fasern allumfassend beschichtet werden, allerdings nur unter verhältnismäßig großem apparativem Aufwand bei gleichzeitig langen Beschichtungszeiten. Für eine Schichtdicke von beispielsweise 0,1 mm ist bei einem PVD/CVD-Verfahren je nach Werkstoff ein Zeitraum von mehreren Stunden bis zu einigen Tagen erforderlich. Somit kann beim PVD/CVD-Verfahren zwar eine Vielzahl von verschiedenen Werkstoffen abgeschieden werden, allerdings nur mit überdurchschnittlich langen Prozesszeiten. Zudem ist die zu beschichtende Bauteilgröße durch die Dimensionierung des erforderlichen Vakuumkessels beschränkt.With PVD / CVD process, for example, fibers can be coated all-encompassing, but only with relatively high expenditure on equipment at the same time long coating times. For a layer thickness For example, 0.1 mm in a PVD / CVD process, depending on the material a period of several hours to several days is required. Thus, while the PVD / CVD process, a variety of different materials can be deposited, but only with above-average process times. In addition, the component size to be coated is limited by the dimensioning of the required vacuum boiler.

Aus der US 5 846 288 ist ein Verfahren zur Herstellung eines elektrisch leitenden Materials, welches beispielsweise zur Herstellung von gepressten oder gesinterten leitenden Streifen oder Stäben verwendet werden kann, bekannt, bei dem in einer Lösung von Silbersalzen aus Zinnoxid hergestellte granulare Partikel beschichtet werden.From the US 5,846,288 is a method for producing an electrically conductive material which can be used, for example, for the production of pressed or sintered conductive strips or rods, in which granular particles produced in a solution of silver salts of tin oxide are coated.

Die Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung eines Metallmatrix-Faserverbundwerkstoffs zu schaffen, das einfach und schnell durchzuführen ist.The object of the invention is to provide a method for producing a metal matrix fiber composite which is simple and quick to perform.

Die Aufgabe wird gelöst durch ein Verfahren zur Herstellung eines Faserverbundwerkstoffs mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausführungsformen und Weiterbildungen des Erfindungsgegenstands sind in den Unteransprüchen angegeben.The object is achieved by a method for producing a fiber composite material having the features of claim 1. Advantageous embodiments and further developments of the subject invention are specified in the dependent claims.

Durch die Erfindung wird ein Faserverbundwerkstoff mit metallischer Matrix geschaffen. Dieser ist gekennzeichnet durch ein aus einzelnen Fasern bestehendes Fasermaterial und eine darauf aufgebrachte, die metallische Matrix bildende metallische Beschichtung, wobei die metallische Beschichtung eine die Fasern umgebende Metallisierungsschicht und eine ihrerseits auf der Metallisierungsschicht aufgetragene metallische Endschicht umfasst.The invention provides a fiber composite material with a metallic matrix. This is characterized by a consisting of individual fibers and a fiber material applied thereto, the metallic matrix forming metallic coating, wherein the metallic coating a metallization layer surrounding the fibers and a metallic end layer, in turn applied to the metallization layer.

Die metallische Beschichtung kann eine zwischen der Metallisierungsschicht und der metallischen Endschicht befindliche zusätzliche metallische Haftschicht umfassen, welche bei thermisch gespritzten Endschichten zur Verbesserung der Haftung vorteilhaft ist.The metallic coating may comprise an additional metallic adhesive layer located between the metallization layer and the metallic end layer, which is advantageous in thermally sprayed final layers to improve adhesion.

Die Metallisierungsschicht kann eine Dicke von 0,5 µm bis 0,5 mm aufweisen.The metallization layer may have a thickness of 0.5 μm to 0.5 mm.

Die zusätzliche metallische Haftschicht kann eine Dicke von 2 µm bis 1 mm bzw. 20 µm bis 200 µm aufweisen.The additional metallic adhesive layer may have a thickness of 2 μm to 1 mm or 20 μm to 200 μm.

Die Fasern können Glas-, Kohlenstoff- und/oder Aramidfasern sein. Besonders bevorzugt werden Fasern aus elektrisch nicht leitendem Material verwendet.The fibers may be glass, carbon and / or aramid fibers. Particular preference is given to using fibers of electrically non-conductive material.

Die Metallisierungsschicht und/oder die zusätzliche metallische Haftschicht kann Kupfer und/oder Nickel enthalten.The metallization layer and / or the additional metallic adhesion layer may contain copper and / or nickel.

Die metallische Endschicht besteht typischerweise aus einem Leichtmetall (z.B. Aluminium), was aus Gewichtsgründen besonders vorteilhaft ist. Es können aber auch Kupfer-Basiswerkstoffe oder Schwermetalle eingesetzt werden.The final metal layer is typically a light metal (e.g., aluminum), which is particularly advantageous for weight reasons. However, it is also possible to use copper base materials or heavy metals.

Das Fasermaterial kann durch ein Gelege (z.B. Faser-Vlies), Gewebe oder Geflecht der Fasern gebildet sein.The fibrous material may be formed by a scrim (e.g., fiber nonwoven), woven or braided fiber.

Gemäß einer Ausführungsform sind die Fasern des Geleges, Gewebes oder Geflechts als solche mit der Metallisierungsschicht oder mit der Metallisierungsschicht und der zusätzlichen metallischen Haftschicht beschichtet, und das Gelege, Gewebe oder Geflecht insgesamt ist mit der Endschicht beschichtet. Ebenso ist es jedoch möglich von einem bereits vorgefertigten Faser-Gelege, -gewebe oder -geflecht auszugehen, das in seiner Gesamtheit zunächst mit einer Metallisierungsschicht und ggf. einer Haftschicht versehen wird, bevor abschließend die Endschicht aufgetragen wird.According to one embodiment, the fibers of the fabric, fabric or braid are as such with the metallization layer or with the Metallization layer and the additional metallic adhesive layer coated, and the scrim, fabric or braid in total is coated with the final layer. However, it is also possible to start from an already prefabricated fiber scrim, fabric or braid, which is initially provided in its entirety with a metallization layer and optionally an adhesive layer, before finally the final layer is applied.

Der Metallmatrix-Faserverbundwerkstoff kann im Flugzeugbau (z.B. Flügel, Ruder etc.), im Automobil-Rennsport (z.B. Spoiler, Verkleidung, Bodengruppe etc.), bei Flugkörpern, Sportgeräten und vielem mehr eingesetzt werden.The metal matrix fiber composite can be used in aircraft construction (e.g., wings, rudders, etc.), automotive racing (e.g., spoilers, fairing, underbody, etc.), missiles, sports equipment, and more.

Erfindungsgemäß ist es vorgesehen, dass auf ein aus einzelnen Fasern bestehendes Fasermaterial eine die metallische Matrix bildende metallische Beschichtung aufgebracht wird, wobei die metallische Beschichtung durch eine die Fasern umgebende Metallisierungsschicht und eine ihrerseits auf die Metallisierungsschicht aufgebrachte metallische Endschicht gebildet wird, die (Endschicht) durch Lichtbogendrahtspritzen hergestellt wird. Ein Aufbringen durch thermisches Spritzen ist besonders einfach, schnell und kostengünstig, und ermöglicht eine hohe Flexibilität hinsichtlich der gewünschten Geometrie.According to the invention, a metallic coating which forms the metallic matrix is applied to a fiber material consisting of individual fibers, wherein the metallic coating is formed by a metallization layer surrounding the fibers and a metallic end layer which in turn is applied to the metallization layer Arc wire spraying is made. Application by thermal spraying is particularly simple, fast and inexpensive, and allows a high degree of flexibility with regard to the desired geometry.

Zusätzlich enthält die metallische Beschichtung eine metallische Haftschicht, die zwischen der Metallisierungsschicht und der metallischen Endschicht aufgebracht wird, was vorteilhaft ist, da die Endschicht durch Lichtbogendraht-spritzen. aufgetragen wird.In addition, the metallic coating contains a metallic adhesive layer that is applied between the metallization layer and the metallic end layer, which is advantageous because the final layer is injected by arc wire. is applied.

Die Metallisierungsschicht kann chemisch/reaktiv oder durch thermisches Spritzen aufgebracht werden.The metallization layer can be applied chemically / reactively or by thermal spraying.

Die zusätzliche metallische Haftschicht wird galvanisch aufgebracht.The additional metallic adhesive layer is applied galvanically.

Die das Fasermaterial bildenden Fasern sind z.B. Glas-, Kohlenstoff- und/oder Aramidfasern. Besondere Vorteile bieten sich jedoch, wenn Fasern aus elektrisch nicht leitendem Material verwendet werden, die durch die oben beschriebene Metallisierungsschicht leitfähig gemacht werden.The fibers forming the fibrous material are e.g. Glass, carbon and / or aramid fibers. However, there are particular advantages in using fibers of electrically nonconductive material which are rendered conductive by the metallization layer described above.

Die Metallisierungsschicht und/oder die zusätzliche metallische Haftschicht kann durch Kupfer und/oder Nickel gebildet werden.The metallization layer and / or the additional metallic adhesion layer can be formed by copper and / or nickel.

Die Fasern des Geleges, Gewebes oder Geflechts können als solche mit der Metallisierungsschicht oder mit der Metallisierungsschicht und der zusätzlichen metallischen Haftschicht beschichtet werden, und das Gelege,.Gewebe oder Geflecht insgesamt mit der Endschicht beschichtet werden. Ebenso ist es möglich, dass das Fasergelege, -gewebe oder -geflecht in seiner Gesamtheit mit der Metallisierungsschicht und ggf. der Haftschicht derart beschichtet wird, dass die Fasern allumfassend beschichtet sind, und dass anschließend die Endschicht aufgetragen wird.As such, the fibers of the fabric, fabric or braid may be coated with the metallization layer or with the metallization layer and the additional metallic adhesion layer, and the fabric, fabric or braid as a whole may be coated with the final layer. It is likewise possible for the fabric layer, woven fabric or braid in its entirety to be coated with the metallization layer and, if appropriate, the adhesion layer in such a way that the fibers are coated in an all-encompassing manner, and then the final layer is applied.

Die Erfindung weist insbesondere den Vorteil auf, dass ein Faserverbundwerkstoff mit metallischer Matrix geschaffen wird, bei dem die Fasern mit der metallischen Matrix, insbesondere der Metallisierungsschicht, kraftschlüssig verbunden sind. Dies ist bei bisherigen Verfahren und MetallMatrix-Verbundwerkstoffen nicht der Fall.The invention has the particular advantage that a fiber composite material with a metallic matrix is provided, in which the fibers are non-positively connected to the metallic matrix, in particular the metallization layer. This is not the case with previous methods and metal matrix composites.

Im Folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung erläutert.In the following an embodiment of the invention will be explained with reference to the drawing.

Die (einzige) Figur zeigt in einer schematisierten vergrößerten Querschnittsansicht einen Schnitt durch einen erfindungsgemäß hergestellten Faserverbundwerkstoff mit metallischer Matrix.The (single) figure shows in a schematic enlarged cross-sectional view a section through a fiber composite material according to the invention with metallic matrix.

Der in der Figur dargestellte Faserverbundwerkstoff, der insgesamt mit dem Bezugszeichen 10 bezeichnet ist, umfasst eine metallische Matrix, welche ein Fasermaterial bindet und umgibt. Das Fasermaterial besteht aus den in der Figur sehr schematisch dargestellten Fasern 1, welche beispielsweise durch elektrisch nicht leitende Glasfasern gebildet sein können, oder z.B. auch durch Kohlenstoff- oder Aramidfasern. Auf den Fasern 1 befindet sich eine metallische leitende Schicht, die nachfolgend auch als Metallisierungsschicht 2 bezeichnet wird, auf welcher wiederum eine metallische Haftschicht 3 aufgebracht sein kann. Die Metallisierungsschicht 2 und die metallische Haftschicht 3 sind jeweils auf den einzelnen Fasern 1 aufgebracht, welche bei dem dargestellten Ausführungsbeispiel zu einem Gittergewebe verarbeitet sind. Die metallische Endschicht 4 dagegen ist auf das Fasergewebe insgesamt aufgebracht. Anstelle eine metallische Haftschicht 3 vorzusehen, kann die metallische Endschicht 4 auch direkt auf die Metallisierungsschicht 2 aufgebracht sein; in diesem Falle befindet sich auf den Einzelfasern 1 lediglich die Metallisierungsschicht 2, die anschließend z.B. zu einem Fasergewebe verarbeitet werden, auf das dann insgesamt die metallische Endschicht 4 aufgebracht wird. Ebenso kann von einem fertigen Fasermaterial (z.B. in Form eines Fasergeflecht-Halbzeuges oder eines Gittergewebes) ausgegangen werden, das in seiner Gesamtheit zunächst mit der Metallisierungsschicht 2 derart versehen wird, dass die einzelnen Fasern 1 des Fasermaterials jeweils allumfassend von der Metallisierungsschicht 2 umgeben bzw. umschlossen sind. Anschließend kann optional eine Haftschicht 3 auf die Metallisierungsschicht 2 aufgetragen werden, um anschließend die Endschicht 4 aufzutragen.The fiber composite material shown in the figure, which is generally designated by the reference numeral 10, comprises a metallic matrix, which binds and surrounds a fiber material. The fiber material consists of the fibers 1 shown very schematically in the figure, which may be formed for example by electrically non-conductive glass fibers, or for example by carbon or aramid fibers. On the fibers 1 is a metallic conductive layer, which is also referred to below as the metallization layer 2, on which in turn a metallic adhesive layer 3 may be applied. The metallization layer 2 and the metallic adhesion layer 3 are each applied to the individual fibers 1, which are processed in the illustrated embodiment to a mesh fabric. In contrast, the metallic end layer 4 is applied to the fiber fabric as a whole. Instead of providing a metallic adhesive layer 3, the metallic end layer 4 can also be applied directly to the metallization layer 2; In this case, only the metallization layer 2 is located on the individual fibers 1, which are then processed, for example, into a fiber fabric, onto which then the metallic final layer 4 is applied. Likewise, it can be assumed that a finished fiber material (for example in the form of a fiber-mesh semifinished product or a mesh fabric) is provided in its entirety first with the metallization layer 2 such that the individual fibers 1 of the fiber material are surrounded in a comprehensive manner by the metallization layer 2 or are enclosed. Subsequently, an adhesion layer 3 may optionally be applied to the metallization layer 2 in order subsequently to apply the final layer 4.

Die Fasern 1 müssen zunächst vorbehandelt werden, um sie haftfest beschichten zu können, insbesondere wenn sie aus elektrisch nicht leitendem Material bestehen (z.B. Glasfasern). Das Aufbringen der metallischen Endschicht 4 erfolgt durch Lichtbogendrahtspritzen. Die Metallisierungsschicht 2 kann beispielsweise reduktiv/chemisch oder durch thermisches Spritzen aufgetragen werden.The fibers 1 must first be pretreated in order to coat them adhesively, in particular if they consist of electrically non-conductive material (for example glass fibers). The application of the metallic end layer 4 is effected by arc wire spraying. The metallization layer 2 can be applied, for example, reductive / chemical or by thermal spraying.

Eine vorherige Aufbringung einer Metallisierungs- und/oder Haftschicht ist nützlich, welche eine intensive Bindung der metallischen Endschicht 4 an die Fasern 1 gewährleistet. Die zusätzliche metallische Haftschicht 3 kann beispielsweise galvanisch oder mittels thermischen Spritzens aufgebracht werden. Die Metallisierungsschicht 2 bzw. die Metallisierungsschicht 2 und die metallische Haftschicht 3 bilden somit die Basis für die metallische Endschicht 4.A prior application of a metallization and / or adhesive layer is useful, which ensures an intensive bonding of the metallic end layer 4 to the fibers 1. The additional metallic adhesive layer 3 can be applied, for example, galvanically or by thermal spraying. The metallization layer 2 or the metallization layer 2 and the metallic adhesion layer 3 thus form the basis for the metallic end layer 4.

Gemäß einer Modifikation kann die Metallisierungsschicht 2 auch auf die einzelnen Fasern 1 aufgebracht werden, während die zusätzliche metallische Haftschicht 3 auf das durch die Fasern 1 gebildete Fasermaterial aufgebracht wird, worauf dann wiederum die metallische Endschicht 4 aufgebracht wird.According to a modification, the metallization layer 2 can also be applied to the individual fibers 1, while the additional metallic adhesion layer 3 is applied to the fiber material formed by the fibers 1, whereupon in turn the metallic end layer 4 is applied.

Ebenso kann, wie bereits voranstehend beschrieben, gleich von einem vorgefertigten (z.B. handelsüblichen) Fasermaterial ausgegangen werden, das in einem ersten Schritt mit der Metallisierungsschicht 2 versehen wird. Hierbei ist darauf zu achten, dass die einzelnen Fasern 1 jeweils von der Metallisierungsschicht 2 umschlossen werden.Likewise, as already described above, a prefabricated (for example commercially available) fiber material can be assumed, which is provided with the metallization layer 2 in a first step. In this case, care must be taken that the individual fibers 1 are each enclosed by the metallization layer 2.

Die Metallisierungsschicht 2 kann typischerweise eine Dicke von 0,5 µm bis 0,5 mm haben, ohne dass die Dicke jedoch auf diesen Bereich beschränkt ist. Die zusätzliche metallische Haftschicht 3 kann eine Dicke von 2 µm bis zu 1 mm, insbesondere von 20 µm bis 200 µm haben, ohne jedoch auf diesen Bereich beschränkt zu sein. Die metallische Endschicht 4 schließlich kann eine sehr unterschiedliche Dicke haben, je nach Anwendungsbereich zwischen 2 µm und 20 mm, bevorzugt zwischen 20 µm und 2 mm.The metallization layer 2 may typically have a thickness of 0.5 μm to 0.5 mm, but the thickness is not limited to this range. The additional metallic adhesive layer 3 may have a thickness of 2 μm to 1 mm, in particular from 20 μm to 200 μm, without, however, being restricted to this range. Finally, the metallic end layer 4 can be a have very different thickness, depending on the application range between 2 microns and 20 mm, preferably between 20 microns and 2 mm.

Die metallische Leitschicht oder Metallisierungsschicht 2 kann beliebige für den Zweck geeignete Metalle enthalten oder durch diese gebildet sein (z.B. Kupfer und/oder Nickel). Die metallische Endschicht 4 kann ebenfalls beliebige geeignete Metalle enthalten oder durch diese gebildet sein. Typischerweise besteht die Endschicht 4 aus Leichtmetallen (z.B. Aluminium), Kupfer-Basiswerkstoffen oder Schwermetallen.The metallic conductive layer or metallization layer 2 may contain or may be formed by any metals suitable for the purpose (e.g., copper and / or nickel). The metallic end layer 4 may also contain or be formed by any suitable metals. Typically, the end layer 4 is made of light metals (e.g., aluminum), copper base materials, or heavy metals.

Die zusätzliche galvanisch oder durch thermisches Spritzen aufgetragene Haftschicht 3 kann ebenfalls Kupfer und/oder Nickel und/oder auch Aluminium oder ein anderes geeignetes Metall enthalten oder durch dieses gebildet sein.The additional electroplated or by thermal spraying adhesive layer 3 may also contain or be formed by copper and / or nickel and / or aluminum or another suitable metal.

Besonders vorteilhaft ist, dass eine kraftschlüssige Verbindung von den Einzelfasern mit dem Metall, insbesondere der Metallisierungsschichten, erzeugt wird. Durch die Schrumpfung flüssig aufgebrachter Metalle bilden sich viele Mikrospalte zwischen der Faser und dem Metall.It is particularly advantageous that a frictional connection of the individual fibers with the metal, in particular the metallization layers, is generated. The shrinkage of liquid applied metals forms many micro-gaps between the fiber and the metal.

Beispiel:Example:

Ein Ausführungsbeispiel eines metallischen Faserverbundwerkstoffs kann folgendermaßen hergestellt werden:

  • Entfetten eines aus Glasfasern 1 gebildeten Gittergewebes in einer alkalischen, wässrigen Abkochentfettung, danach gründliches Spülen in VE-Wasser;
  • chemische (außenstromlose) Metallisierung (z.B. chemisch Kupfer oder chemisch Nickel) des entfetteten Glasfaser-Gittergewebes zur Erzeugung einer dünnen, elektrisch leitfähigen Umhüllung der bisher elektrisch nichtleitenden Fasern 1, sowie gründliches Spülen;
  • galvanisches Verstärken der mit der Leitschicht bzw. Metallisierungsschicht 2 dünn beschichteten Fasern 1 auf eine Schichtdicke von z.B. 150 µm (z.B. Nickelbad, Stromdichte 2-3A/dm2), um eine zusätzliche metallische Haftschicht 3 auszubilden, sowie wiederum gründliches Spülen und Auftrocknen des Glasfaser-Gittergewebes;
  • beidseitiges, leichtes Strahlen der galvanisierten (vernickelten) Oberfläche mit Korund (Korngröße z.B. 0 bis 100 µm) in einer Injektorstrahlanlage, um dadurch die Oberfläche aufzurauen;
  • beidseitiges Beschichten der aufgerauten Oberfläche mittels Lichtbogendrahtspritzens mit einem Leichtmetall (z.B. Aluminium). Das Lichtbogendrahtspritzen kann solange durchgeführt werden bis die Lücken des ursprünglichen Glasfasergitters geschlossen sind und eine kompakte, durchgehende Schicht (Verbund) entstanden ist. Dieser Verbund zeichnet sich durch eine hohe Festigkeit bei gleichzeitig geringem Eigengewicht aus. Ferner sind mechanische Bearbeitungsmethoden wie Bohren, Fräsen, Schleifen, Polieren oder ähnliches dieses Verbundes möglich.
An embodiment of a metallic fiber composite material can be produced as follows:
  • Degreasing a woven fabric formed from glass fibers 1 in an alkaline, aqueous Abkochentfettung, then thorough rinsing in deionized water;
  • chemical (electroless) metallization (eg, chemical copper or chemical nickel) of the degreased fiberglass mesh to produce a thin, electrically conductive covering of the previously electrically non-conductive fibers 1, and thorough rinsing;
  • galvanically reinforcing the thinly coated with the conductive layer or metallization layer 2 fibers 1 to a thickness of eg 150 microns (eg nickel bath, current density 2-3A / dm 2 ) to form an additional metallic adhesive layer 3, and in turn thorough rinsing and drying of the glass fiber -Gittergewebes;
  • bilateral, light blasting of the galvanized (nickel-plated) surface with corundum (particle size eg 0 to 100 μm) in an injector blasting machine, in order thereby to roughen the surface;
  • Double-sided coating of the roughened surface by means of arc wire spraying with a light metal (eg aluminum). The arc wire spraying can be carried out until the gaps of the original glass fiber grid are closed and a compact, continuous layer (composite) is formed. This composite is characterized by high strength and low weight at the same time. Furthermore, mechanical processing methods such as drilling, milling, grinding, polishing or the like of this composite are possible.

Der beschriebene Faserverbundwerkstoff mit metallischer Matrix bildet einen in hohem Maße festen, nicht entflammbaren, bruchunempfindlichen Werkstoff ohne Splitterbruchverhalten mit einem optimalen Verhältnis von Festigkeit zu Gewicht. Bei den Matrixwerkstoffen ist man nicht auf Leichtmetalle wie z.B. Aluminium beschränkt, es können beliebige andere geeignete Metalle verwendet werden, welche in einer geeigneten Form als Schicht auf das vorbereitete Fasermaterial aufgebracht werden können. Die eigentliche Matrix wird im Wesentlichen erst durch diese Beschichtung gebildet, und eine kraftschlüssige Verbindung zwischen Fasern und metallischer Matrix wird erzeugt.The described fiber matrix composite with metallic matrix forms a highly solid, non-flammable, unbreakable material without fragmentation behavior with an optimum ratio of strength to weight. The matrix materials are not limited to light metals, e.g. Aluminum, any other suitable metals can be used, which can be applied in a suitable form as a layer on the prepared fiber material. The actual matrix is formed essentially only by this coating, and a non-positive connection between the fibers and the metallic matrix is produced.

Durch Nutzung einer Kombination eines galvanischen Verfahrens (gerichteter Faraday'scher Prozess) zur Erzeugung einer Metallisierungs-, Leit- oder Haftschicht mit einem Prozess hoher Auftragsgeschwindigkeit, insbesondere thermischem Spritzen, ist eine wirksame Umhüllung des Fasermaterials mit hoher Auftragsgeschwindigkeit möglich. Dabei ist man nicht auf die gängigen Metalle der elektrochemischen Spannungsreihe beschränkt, wie es z.B. bei dem galvanischen Verfahren der Fall ist. Was die Größe der herstellbaren Faserverbunde, also letztlich der herstellbaren Bauteile betrifft, sind nahezu keine Grenzen gesetzt, da thermisches Spritzen bei Bauteilen von nahezu beliebiger Größe durchgeführt werden kann. Ein besonderer Vorteil gegenüber beispielsweise PVD/CVD-Verfahren besteht zum einen darin, dass die Auftragsgeschwindigkeit wesentlich größer ist, dass die Fasern von allen Seiten beschichtet werden können, und dass hinsichtlich der Größe der Bauteile nicht die Grenzen wie bei den besagten Vakuumverfahren bestehen, bei denen die Dimension durch die Größe des umgebenden Vakuumkessels beschränkt sind.By using a combination of a galvanic process (directed Faraday process) to produce a metallization, conduction or Adhesive layer with a high-speed process, in particular thermal spraying, an effective wrapping of the fiber material is possible with high order speed. It is not limited to the common metals of the electrochemical series, as it is the case for example in the galvanic process. As far as the size of the manufacturable fiber composites, ie ultimately the manufacturable components, are concerned, there are virtually no limits, since thermal spraying can be carried out on components of virtually any size. A particular advantage over, for example PVD / CVD method consists firstly that the order speed is much greater, that the fibers can be coated from all sides, and that in terms of the size of the components are not the limits as in the said vacuum process, at where the dimension is limited by the size of the surrounding vacuum vessel.
