Description
Die vorliegende Erfindung betrifft ein Faseraaterial fur die Herstellung von selbsttragenden Verkleidungsplatten im allgemeinen insbesondere Verkleidungsplatten fär &en Gebrauch in Kraftfahrzeugen wie Heckscheibenunterflachen, Hutauflagen, Turplatten, Wagendecken, Wagendächern u. dgl., und das Verfahren zur Herstellung desselben.The present invention relates to a Faseraaterial for the production of self-supporting lining panels, in general, in particular lining panels for everyone & s use in motor vehicles, such as rear window bottom surfaces, Hutauflagen, Turplatten, car covers, car roofs u. The like., And the same, the method for producing the same.
IlIl
Zur Herstellung von Verkleidungsplatten der erwähnten Art ist die Verwendung von Faserkonglomerat bekannt und verbreitet, das durch Pressen von natürlichen oder synthetischen Fasern erhalten wird. In jüngerer Zeit wurden zwecks Herabsetzung der Dichte und daher des Gewichtes dieser Faserkonglomerate formpressbare Materialien erzeugt, bei denen die naturliehen und/oder synthetischen Fasern mit Polyesterharzen gebunden werden, wobei eine Mischung erhalten wird, aus der die vorgeformte Verkleidungsplatte durch unmittelbares Formpressen erhalten wird«.For the production of cladding panels of the type mentioned the use of fiber conglomerate is known and widespread, obtained by pressing natural or synthetic Fibers is obtained. More recently, in order to reduce the density and therefore the weight of these Fiber conglomerates molded materials produced in which the natural and / or synthetic fibers with Polyester resins are bonded, a mixture being obtained from which the preformed cladding panel obtained by direct compression molding «.
Dieses bekannte und neuere Material besitzt zwar gute mechanische Festigkeitseigenschaften zusammen mit einem geringen spezifischen Gewicht, weist aber bedeutende Nachteile auf, insbesondere was die Herstellungsverfahren anbelangt. Das Polyesterbindemittel wird nämlich normalerweise gespritzt und dies bringt bedeutende Probleme mit sich, die an die Gesundheitsschädlichkeit im Arbeitsraum mit der folglichen Notwendigkeit von komplizierten und kostspieligen Schutzeinrichtungen gebunden sind. Das Formpressen des Materials muß ferner in sehr kurzer Zeit der Imprägnierungsphase folgen, was den Herstellungszyklus, insbesondere bei Stücken mit beträchtlichen AbmessungenThis known and newer material has good mechanical properties Strength properties together with a low specific weight, but has significant disadvantages on, especially with regard to the manufacturing process. Namely, the polyester binder is normally sprayed and this brings with it significant problems related to the health hazards in the work area with the consequent need for complex and expensive protective devices are bound. The compression molding of the material must also be carried out in a very short time Impregnation phase follow what the manufacturing cycle, especially for pieces of considerable dimensions
