Description

Die Erfindung betrifft ein Verfahren zum Herstellen eines Schichtkörpers aus faserverstärktem Kunstharz gemäß dem Oberbegriff des Patentanspruchs 1The invention relates to a method for producing a laminated body made of fiber-reinforced synthetic resin according to the preamble of claim 1

Aus der Zeitschrift »Kunststoffe« (Band 52,1962, Heft 12, S. 742 — 747) ist ein Verfahren mit diesen Merkmalen bekannt, bei dem zur Verbesserung der Oberflächenqualität der herzustellenden Schichtkörper vorzugsweise synthetische Faservliese in eine Feinschicht eingearbeitet werden. Eine eingearbeitete synthetische Fasereinlage in der harzangereicherten Oberfläche trägt zur Festigung und Erhaltung der Gesamtstruktur des Schichtkörpers bei und schützt die darunterliegenden Schichten gegen mechanische und witterungsbedingte Einflüsse. Die Außenfläche des Schichtkörpers ist jedoch im wesentlichen glatt, so daß sie selbst unter derartigen Einflüssen leidet und optisch bald unansehnlich wird.From the magazine »Kunststoffe« (Volume 52, 1962, issue 12, pp. 742-747) a method with these features is known in which to improve the Surface quality of the laminated body to be produced, preferably synthetic fiber fleece in a fine layer be incorporated. An incorporated synthetic fiber insert in the resin-enriched one Surface contributes to the consolidation and maintenance of the overall structure of the layered body and protects the underlying layers against mechanical and weather-related influences. The outer surface of the However, the laminate is essentially smooth so that it suffers from such influences itself and visually soon becomes unsightly.

Um Platten für Fassadenverkleidungen mit einer auch gegen stärkere mechanische Beanspruchung schützenden Dekorschicht zu versehen, ist es aus der DT-AS 20 42 404 bekannt, auf den Schichtkörper eine Harzschicht aufzutragen, auf die dann gekörntes mineralisches Material aufgebracht wird. Dieses Verfahren bleibt jedoch aus verarbeitungstechnischen Gründen im wesentlichen auf die Herstellung biegungssteifer Platten für Verkleidungen beschränkt.To panels for facade cladding with a protective layer against strong mechanical stress To provide a decorative layer, it is known from DT-AS 20 42 404 to apply a resin layer to the laminate to apply, to which granular mineral material is then applied. This method however, for processing reasons, it remains essentially to manufacture rigid panels limited for disguises.

Aus der US-PS 37 23 220 ist schließlich ein weiteres Verfahren zur Herstellung eines Schichtkörpers bekanntgeworden, der als Oberflächenschicht ein Textilgewebe mit einem Overlay aufweist, das unter Einsatz von Polstern und hohen Drücken derart verfcrmt wird, daß an seiner Außenfläche annähernd die textile Struktur der Gewebeeinlage in Erscheinung tritt. Dieses Verfahren ist jedoch infolge des notwendigen Einsatzes von Pressen verhältnismäßig aufwendig und daher ebenfalls zur Herstellung verschieden (»eformter Schichtkörper in kleineren Stückzahlen ungeeignet.From US-PS 37 23 220 a further method for the production of a laminated body has finally become known, which has a textile fabric with an overlay as a surface layer, which is used is so distorted by upholstery and high pressures that on its outer surface almost the textile Structure of the fabric insert appears. However, this procedure is due to the necessary effort relatively complex of presses and therefore also different for production (»eformter Layered body unsuitable in smaller numbers.

Aufgabe der Erfindung ist es daher, ein Verfahren der eingangs genannten Art aufzuzeigen, mit dem auf einfache Weise und ohne aufwendige Anlagen ein Schichtkörper herstellbar ist, dessen Außenfläche so ausgebildet ist, daß sie durch mechanische und witterungsbedingte Einflüsse optisch nicht in Mitleidenschaft gezogen wird.The object of the invention is therefore to provide a method of the type mentioned above, with which on a layered body can be produced in a simple manner and without complex systems, the outer surface of which is so is designed so that it is not optically affected by mechanical and weather-related influences is pulled.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 genannten Merkmale gelöstAccording to the invention, this object is achieved by the features mentioned in the characterizing part of claim 1 solved

Auf diese Weise lassen sich im einfachen Handauflegeverfahren mühelos und ohne Einsatz von Pressen unmittelbar von der Positivform eines Modells alle Arten von Formteüen abnehmen, deren Außenflächen eine textile Struktur aufweisen, die Kratzer u.dgl. optisch nicht mehr in Erscheinung treten läßt und die zudem den Schichtkörpern ein äußerst dekoratives Aussehen gibt Die textile Struktur bleibt erhalten, da nur Kunstharz bis zur Sättigung der Saugfähigkeit zugeführt ist und kein die textile Struktur ausgleichendes Harz.In this way, the simple hand lay-up process can be carried out effortlessly and without the use of presses remove all types of molded parts directly from the positive form of a model, their outer surfaces have a textile structure that prevents scratches and the like from appearing and which also gives the layered bodies an extremely decorative appearance. The textile structure is retained because only synthetic resin is added to the point of saturation of absorbency and nothing that balances the textile structure Resin.

pin gemäß der Erfindung hergestellter Schichtkörper läßt sich bevorzugterweise als Karosserieformteil für Kraftfahrzeuge verwenden.pin manufactured according to the invention can be preferably used as a molded body part for Use motor vehicles.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert, die eine schematische Schnittdarstellung des Schichtkörpers zeigt.An embodiment of the invention is explained in more detail with reference to the drawing, which shows a shows a schematic sectional view of the laminate.

Als Trägerlaminat 10 wird üblicherweise eine glasfaserverstärkte Kunststoffschicht verwendet, die auf eine mit 11 angedeutete Positivform eines Modells aufgebracht wird. Das Trägerlaminat 10 wird dann mit einem sogenannten Textilfaserlaminat 12 beschichtet, das beispielsweise aus einem mit Harzen oderA glass fiber reinforced plastic layer is usually used as the carrier laminate 10, which on a positive form of a model indicated by 11 is applied. The carrier laminate 10 is then coated with a so-called textile fiber laminate 12, that for example from one with resins or

Harzlösungen getränkten Baumwollgewebe besteht. Das Baumwollgewebe, das entsprechend der gewünschten Oberflächenstruktur verschiedene Feinheitsgrade aufweisen kann, wird derart getränkt, daß seine textile Struktur an der Außenfläche voll erhalten bleibt. Als härtbare Formmasse oder Bindemittel werden vorzugsweise EP- und UP-Harze verwendet. Anstelle des genannten Baumwollgewebes können auch Textilien aus Kunstfasern verarbeitet werden, deren einzelne Fasern sich allerdings im Gegensatz zu den Naturfasern nicht mi: Bindemittel vollsaugen und die daher farbechter sind Saugfähigkeit ist hier als Aufnahmefähigkeit des genannten Oberflächenfasermaterials im Zusammenhang zur Flüssigkeit zu verstehen, bis zu dem Zustand, bei dem die textile Struktur verloren zu gehen beginnt.Resin solutions soaked cotton fabric consists. The cotton fabric that according to the desired Surface structure can have different degrees of fineness, is soaked in such a way that its textile Structure on the outer surface is fully preserved. As the curable molding compound or binder are preferred EP and UP resins used. Instead of the cotton fabric mentioned, textiles can also be used are processed from synthetic fibers, the individual fibers of which, however, in contrast to natural fibers not mi: soak up binders and are therefore more colourfast. Absorbency is here as absorption capacity to understand the surface fiber material mentioned in connection with the liquid, up to the State in which the textile structure begins to be lost.

Die Widerstandsfähigkeit des fertigen Schichikörpers gegen äußere mechanische Einflüsse kann durch Auftragen eines transparenten Schutzlacks, z. B. Desmodur-Desmophen-Lack, weiter verbessert werden,The resistance of the finished layer against external mechanical influences can be achieved by Applying a transparent protective varnish, e.g. B. Desmodur-Desmophen lacquer, be further improved,

S5 ohne daß die textile Oberflächenstruktur verlorengeht.S5 without losing the textile surface structure.

Bei Verwendung des Schichtkörper für Kraftfahrzeugkarosserieteile ist eino sonst üblicherweise gewünschte Einfärbung des Kunstharzes nicht erforderlich, da die Farbtönung durch die Auswahl des verwendeten Textils bereits vorgegeben ist.When using the laminated body for automobile body parts If the otherwise commonly desired coloring of the synthetic resin is not required, because the color shade is already specified by the selection of the textile used.
