Abstract
(DE)
Vorgestellt wird ein Verfahren zur Herstellung von Innenausstattungsteilen für Verkehrsmittel, insbesondere Kraftfahrzeuge, die aus einem tragenden, formerhaltenden Teil und einem die Sichtseite des Innenausstattungsteils bildenden Dekorteil bestehen, wobei das tragende, formerhaltende Teil aus einem mittels Verstärkungseinlagen versteiften Kunststoffmaterial besteht, bei dem erhebliche Verbesserungen dadurch erreicht werden, daß das Kunststoffmaterial aus natürlichen oder recycelten Polyolen und Isocyanaten besteht und für die Verstärkungseinlage ein aus natürlichen Fasern bestehendes Material verwendet wird, wobei das aus natürlichen Fasern bestehende Material in eine der Raumform des herzustellenden Innenausstattungsteils entsprechend gestaltete sowie beheizbare (Schäum-)Form eingelegt und anschließend das reaktionsfähige, schäumbare PUR-Gemisch mit einem Dosierdruck von 100 bis zu 300 bar in die (Schäum-)Form eingebracht sowie in der (Schäum-)Form bei einem Reaktionsdruck zwischen 3 und 300 bar aufgeschäumt und ausgehärtet wird.
(EN)
A process is disclosed for producing interior trims for transport means, in particular motor vehicles, that consist of a bearing, dimensionally stable part and of a decorative part that forms the visible side of the interior trim. The bearing, dimensionally stable part is made of plastic materials stiffened by reinforcing inserts. In order to considerably improve the process, the plastic materials consist of natural or recycled polyols and isocyanates and a material made of natural fibres is used for the reinforcing inserts. The material made of natural fibres is laid into a heatable (foaming) mould whose shape corresponds to that of the interior trim to be produced, the reactive, foamable polyurethane mixture is injected into the mould at a dosing pressure from 100 to 300 bars, then foamed and hardened in the mould at a reaction pressure from 3 to 300 bars.

L'invention concerne un procédé de fabrication de garnitures intérieures de moyens de transport, notamment de véhicules à moteur, constituées d'une partie porteuse indéformable et d'une partie décorative qui forme la face visible de la garniture intérieure. La partie porteuse indéformable est constituée d'une matière plastique renforcée par des couches de renforcement. Afin d'améliorer considérablement le procédé, les matières plastiques utilisées sont des polyols et des isocyanates naturels ou recyclés et on utilise un matériau constitué de fibres naturelles pour former les couches de renforcement. Le matériau constitué de fibres naturelles est placé dans un moule chauffable de moussage dont la forme correspond à celle de la garniture intérieure que l'on veut produire, puis on introduit le mélange réactif moussant de polyuréthanne dans le moule sous une pression de dosage comprise entre 100 et 300 bars et on le fait mousser et durcir dans le moule sous une pression de réaction de 3 à 300 bars.
