Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Verkleben von Formstücken aus Kunststoffmatrix-enthaltenden Faserstoff-Zusammensetzungen (KFZ) mit Polyurethanzusammensetzungen aufweisend die Schritte: a) Applizieren von IR-Strahlung auf einen definierten Bereich eines Formstücks aus KFZ; b) Applizieren einer Polyurethanzusammensetzung auf den definierten Bereich des Formstücks; c) Fügen der Polyurethanzusammensetzung auf dem definierten Bereich des Formstücks mit einem Substrat; d) Aushärten der Polyurethanzusammensetzung. Das erfindungsgemässe Verfahren zeichnet sich durch einen raschen Festigkeitsaufbau (Frühfestigkeit) der Polyurethanzusammensetzung aus, dadurch kann der unter ihrer Verwendung erzeugte Verbund schon kurze Zeit nach der Applikation der Polyurethanzusammensetzung und dem Fügen des Formstücks mit dem Substrat bearbeitet oder belastet werden.
(EN)
The invention describes a method for gluing molded articles made of plastic matrix-fiber composites with polyurethane compositions, the method comprising the steps: a) application of IR radiation to a defined region of a molded article made of plastic matrix-fiber composite; b) application of a polyurethane composition to the defined region of the molded article; c) bonding the polyurethane composition to the defined region of the molded article to a substrate; and d) curing of the polyurethane composition. The method according to the invention is distinguished by a rapid hardening (early strength) of the polyurethane composition; the composite produced by the use thereof can therefore be stressed or machined just a short time after application of the polyurethane composition and bonding of the molded article to the substrate.
(FR)
L'invention concerne un procédé de collage de pièces moulées constituées de compositions fibreuses contenant une matrice plastique (KFZ) au moyen de compositions polyuréthanes. Ledit procédé comprend les étapes suivantes : a) application d'un rayonnement IR sur une zone définie d'une pièce moulée constituée de FKZ ; b) application d'une composition polyuréthane sur la zone définie de la pièce moulée ; c) assemblage à un substrat de la composition polyuréthane appliquée sur la zone définie de la pièce moulée; d) durcissement de la composition polyuréthane. L'invention est caractérisée par un établissement rapide de la résistance (résistance initiale) de la composition polyuréthane, ce qui permet de traiter ou de solliciter le composite ainsi produit dans un bref délai après l'application de la composition polyuréthane et après l'assemblage de la pièce moulée au substrat.
