BeschreibungDescription Formteil aus VerbundmaterialMolded part made of composite material

Die Erfindung betrifft ein Formteil aus Verbundmaterial, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a molded part made of composite material, with the features of the preamble of claim 1.

Das Formteil dient dekorativen und/oder funktionellen Zwecken. Seine Verwendung ist vielseitig. Es ist als Karosserieteil oder für die innenausstattung eines Personenkraftwagens, beispielsweise als Mittelkonsole, Armaturenbrett oder Türverkleidung, ebenso verwendbar wie beispielsweise im Möbel- und Messebau oder in der Innenarchitektur.The molded part serves decorative and/or functional purposes. Its use is versatile. It can be used as a body part or for the interior of a passenger car, for example as a center console, dashboard or door panel, as well as in furniture and exhibition construction or in interior design.

Es ist bekannt, derartige Formteile als Dekorteile aus faserverstärktem, durchsichtigem Kunststoff herzustellen, so daß der im Kunststoff eingebettete Faserwerkstoff sichtbar ist. Anschließend wird die Oberfläche des Formteils geschliffen und mit einem Klarlack lackiert. Jedoch entstehen bei der Herstellung des Formteils winzige, bis zur Oberfläche reichende Lunker. An den Lunkern bildet der Klarlack winzige Krater, die die Oberflächengüte verschlechtern. Die Oberfläche des lackierten Formteils muß zum Entfernen der Krater nochmals geschliffen oder gespachtelt und anschließend nochmals lackiert werden. Dieses Schleifen und Lackieren muß mehrfach wiederholt werden. Zumindest das Schleifen muß wegen der komplizierten geometrischen Form, die das Formteil oftmals hat, von Hand erfolgen. Das mehrmalige Schleifen und Lackieren verursacht einen großen Herstellungsaufwand. Zudem entstehen viele Ausschußteile.It is known to produce such molded parts as decorative parts from fiber-reinforced, transparent plastic, so that the fiber material embedded in the plastic is visible. The surface of the molded part is then sanded and painted with a clear varnish. However, during the production of the molded part, tiny cavities that reach to the surface are created. The clear varnish forms tiny craters in the cavities, which impair the surface quality. The surface of the painted molded part must be sanded or filled again to remove the craters and then painted again. This sanding and painting must be repeated several times. At least the sanding must be done by hand because of the complicated geometric shape that the molded part often has. The repeated sanding and painting causes a lot of production effort. In addition, many rejects are created.

Aufgabe der Erfindung ist ein Formteil aus Verbundmaterial der eingangs genannten Art zu schaffen, das sich einfach, schnell und automatisierbar herstellen läßt, sowie ein Verfahren zu dessen Herstellung.The object of the invention is to provide a molded part made of composite material of the type mentioned above, which can be produced simply, quickly and automatically, as well as a method for its production.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

&iacgr;&ogr; Erfindungsgemäß besteht das Formteil aus einem Verbundmaterial, das einen lichtdurchlässigen Thermoplast aufweist, auf dessen Rückseite als Dekorelement beispielsweise ein Kohlefasergewebe oder -gelege aufgebracht ist. Die Rückseite ist die beispielsweise einem Fahrgastraum abgewandte Oberfläche des Formteils. Durch den lichtdurchlässigen Thermoplast hindurch ist das Dekorelement von einer dem Fahrgastraum zugewandten Vorderseite des Formteils her sichtbar. Das erfindungsgemäße Formteil aus Verbundwerkstoff hat dasselbe Aussehen und dieselbe Funktion wie ein faserverstärkter, lichtdurchlässiger Kunststoff, ist jedoch in der Herstellung erheblich weniger aufwendig. Seine mechanischen Eigenschaften entsprechen denen eines herkömmlichen, faserverstärkten Kunststoffs. Hinzu kommen seine Produktsicherheit im Sinne von Reproduzierbarkeit und Qualitätssicherung.&iacgr;&ogr; According to the invention, the molded part consists of a composite material that has a translucent thermoplastic, on the back of which a carbon fiber fabric or scrim is applied as a decorative element. The back is the surface of the molded part facing away from a passenger compartment, for example. The decorative element is visible through the translucent thermoplastic from a front side of the molded part facing the passenger compartment. The molded part made of composite material according to the invention has the same appearance and the same function as a fiber-reinforced, translucent plastic, but is considerably less complex to manufacture. Its mechanical properties correspond to those of a conventional, fiber-reinforced plastic. In addition, there is its product safety in terms of reproducibility and quality assurance.

Weiterer Vorteil des erfindungsgemäßen Formteils aus Verbundmaterial ist seine Recycelfähigkeit: Das aus Thermoplast, also aus einem Polymer bestehende 5 Formteil läßt sich mittels eines geeigneten Lösungsmittels (beispielsweise Alkohol) auflösen und dadurch vom Dekoreiement trennen. Nach Abscheiden des Lösungsmittels kann das gewonnene Thermoplast (Pulver, Granulat) einer erneuten Kunststoffverarbeitung zugeführt werden.Another advantage of the molded part made of composite material according to the invention is its recyclability: The molded part made of thermoplastic, i.e. a polymer, can be dissolved using a suitable solvent (e.g. alcohol) and thus separated from the decorative element. After the solvent has been separated, the thermoplastic (powder, granulate) obtained can be fed into a new plastic processing process.

Der das Formteil bildende Thermoplast kann milchig oder transparent sein, wobei die Struktur beispielsweise eines als Dekorelements auf der Rückseite aufgebrachten Gewebes durch das Thermoplast hindurch erkennbar ist. Für dekorative Teile ist das das Formteil bildende Thermoplast vorzugsweise glasklar oder auch getönt, so daß das auf der Rückseite aufgebrachte Dekorelement von der Vorderseite aus sichtbar ist.The thermoplastic forming the molded part can be milky or transparent, whereby the structure of, for example, a fabric applied as a decorative element to the back can be seen through the thermoplastic. For decorative parts, the thermoplastic forming the molded part is preferably crystal clear or tinted, so that the decorative element applied to the back is visible from the front.

Das Dekorelement kann beispielsweise aus Fasern bestehen, es kann ein Fasergewebe oder Fasergelege sein, wegen des Aussehens insbesondere einThe decorative element can, for example, consist of fibres, it can be a fibre fabric or fibre fabric, because of its appearance in particular a

Kohlefasergewebe. Auch einfarbige oder buntbedruckte Textilien, Papier oder Holzfurniere kommen als Dekorelement in Betracht.Carbon fiber fabric. Single-colored or colorfully printed textiles, paper or wood veneers can also be considered as decorative elements.

Ein einfaches Herstellungsverfahren besteht im Tiefziehen (Vakuumverformen) des Formteils aus einer Thermoplast-Platte. Dabei muß die Oberfläche auf der &iacgr;&ogr; Vorderseite des Formteils nicht glatt sein, sondern kann durch Verwendung einer eine strukturierte Oberfläche aufweisendenden Thermoplast-Platte oder durch Tiefziehen in eine Negativ-Form, die eine Oberflächenstruktur aufweist, eine strukturierte Oberfläche auf der Vorderseite erhalten.A simple manufacturing process consists in deep drawing (vacuum forming) the molded part from a thermoplastic sheet. The surface on the front of the molded part does not have to be smooth, but can be given a structured surface on the front by using a thermoplastic sheet with a structured surface or by deep drawing into a negative mold that has a surface structure.

Das Aufbringen des Dekorelements auf der Rückseite des Formteils kann erfindungsgemäß mittels eines polymerisierenden Monomers erfolgen, das auf die Rückseite des Formteils beispielsweise aufgestrichen, aufgegossen, oder aufgespritzt wird, wobei das Dekorelement an die Rückseite des Formteils angedrückt wird. Das polymerisierende Monomer verbindet sich mit dem aus einem Thermoplast, also ebenfalls aus einem Polymer, bestehenden Formteil zu einem Formteil aus einheitlichem Werkstoff, oder jedenfalls zu einem Formteil ohne erkennbare Grenzschicht zwischen dem Thermoplast und dem polymerisierten Monomer.The application of the decorative element to the back of the molded part can be carried out according to the invention by means of a polymerizing monomer, which is, for example, spread, poured or sprayed onto the back of the molded part, whereby the decorative element is pressed onto the back of the molded part. The polymerizing monomer combines with the molded part consisting of a thermoplastic, i.e. also a polymer, to form a molded part made of a uniform material, or at least a molded part without a recognizable boundary layer between the thermoplastic and the polymerized monomer.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die Figuren 1 bis 5 zeigen in stark vereinfachter, schematisierter Darstellung Verfahrensschritte zur Hersteilung eines erfindungsgemäßen Formteiis.The invention is explained in more detail below using an embodiment shown in the drawing. Figures 1 to 5 show, in a highly simplified, schematic representation, process steps for producing a molded part according to the invention.

Die Herstellung des erfindungsgemäßen Formteils erfolgt durch sog.The molded part according to the invention is produced by so-called

Vakuumverformung: Eine ebene, durchsichtige Thermoplast-Platte 10 wird zur Verformung mit Infrarotstrahlern 12 auf eine Verformungstemperatur von ca. 1700C erwärmt (Fig. 1), auf eine Form 14 aufgelegt und anschließend in die Form 14 tiefgezogen (Fig. 2). Zum Tiefziehen wird zwischen der Thermoplast-Platte und der Form 14 eingeschlossene Luft durch in der Form 14 angebrachte Saugkanäle 16 mit einer nicht dargestellten Vakuumpumpe abgesaugt (Pfeil P), wodurch sich die Thermoplast-Platte 10 ohne Einschluß von Zwischenräumen an die Oberfläche der Form 14 anlegt.Vacuum forming: A flat, transparent thermoplastic plate 10 is heated to a forming temperature of approx. 170 0 C (Fig. 1) using infrared radiators 12 for forming, placed on a mold 14 and then deep-drawn into the mold 14 (Fig. 2). For deep-drawing, air trapped between the thermoplastic plate and the mold 14 is sucked out through suction channels 16 installed in the mold 14 using a vacuum pump (not shown) (arrow P), whereby the thermoplastic plate 10 adheres to the surface of the mold 14 without leaving any gaps.

Im Ausführungsbeispiel ist die Form 14 eine Negativform, an der die geformte Thermoplast-Platte 10 mit einer Vorderseite anliegt. Es kann jedoch ebenso mit einer Positivform gearbeitet werden, an der die Thermoplast-Platte 10 mit einer Rückseite anliegt.In the exemplary embodiment, the mold 14 is a negative mold, against which the molded thermoplastic plate 10 rests with a front side. However, it is also possible to work with a positive mold, against which the thermoplastic plate 10 rests with a back side.

Nach Abschalten der Infrarot-Strahler 12 kühlt die Thermoplast-Platte 10 ab und erstarrt. Im nächsten Arbeitsschritt wird auf die Rückseite der geformten Thermopiast-Platte 10 ein Monomer aufgetragen (Fig. 3) und ein Kohlefasergewebe als Dekorelement 18 aufgelegt (Fig. 4).After the infrared radiators 12 are switched off, the thermoplastic plate 10 cools down and solidifies. In the next step, a monomer is applied to the back of the formed thermoplastic plate 10 (Fig. 3) and a carbon fiber fabric is placed on top as a decorative element 18 (Fig. 4).

Das Dekorelement 18 wird mittels eines zur Form 14 komplementären Stempels 20 mit der geformten Thermoplast-Platte 10 verpreßt, während der Monomer polymerisiert und sich dadurch mit der Thermoplast-Platte 10 zu einem einheitlichen Werkstoff ohne Grenzschicht verbindet. Die geformte Thermoplast-Platte 10 bildet mit dem auf ihrer Rückseite mittels des poiymerisierten Monomers als Dekorelement 18 aufgebrachten Kohlefasergewebe das erfindungsgemäße Verbundmaterial-Formteil.The decorative element 18 is pressed with the molded thermoplastic plate 10 by means of a stamp 20 complementary to the mold 14, while the monomer polymerizes and thereby bonds with the thermoplastic plate 10 to form a uniform material without a boundary layer. The molded thermoplastic plate 10 forms the composite material molded part according to the invention with the carbon fiber fabric applied to its back side by means of the polymerized monomer as a decorative element 18.

Auf die beschriebene Weise läßt sich sehr schnell ein Verbundmateriai-Formteil 5 10, 18 mit hoher Oberflächengüte auf der Vorderseite herstellen, das das Aussehen und die mechanischen Eigenschaften eines kohlefaserverstärkten Kunststoffteils hat. Eine Nachbearbeitung der Oberfläche erübrigt sich.In the manner described, a composite material molded part 5 10, 18 with a high surface quality on the front side can be produced very quickly, which has the appearance and mechanical properties of a carbon fiber reinforced plastic part. There is no need for any post-processing of the surface.

Es lassen sich auch andere Materialien, beispielsweise bedrucktes Textilgewebe oder Papier anstelle des Kohlefasergewebes 16 auf der Thermoplast-Platte 10 anbringen, um dem hergestellten Formteil 10, 18 ein gewünschtes Aussehen zu geben. Das ein Dekorelement bildende Kohlefasergewebe 16 kann vor, während oder auch nach der Verformung auf der Thermoplast-Platte 10 angebracht werden.Other materials, such as printed textile fabric or paper, can also be applied to the thermoplastic plate 10 instead of the carbon fiber fabric 16 in order to give the produced molded part 10, 18 a desired appearance. The carbon fiber fabric 16, which forms a decorative element, can be applied to the thermoplastic plate 10 before, during or after the deformation.

Die Thermoplast-Platte 10 besteht aus Polymethylmethacrylat (PMMA), also aus einem Polymer. Verwendbar sind beispielsweise auch Polycarbonat, Polyethylen, etc.The thermoplastic plate 10 is made of polymethyl methacrylate (PMMA), i.e. a polymer. Polycarbonate, polyethylene, etc. can also be used.
