Abstract

A method for gluing of shaped bodies made of fiber composite compositions containing a plastic matrix KFZ with polyurethane compositions, the method including: a) application of IR radiation to a defined region of the shaped body of KFZ; b) application of a polyurethane composition to the defined region of the shaped body; c) bonding of the polyurethane composition on the defined region of the shaped body to a substrate; and d) curing of the polyurethane composition. The method is distinguishable by a rapid strengthening (early strength) of the polyurethane composition, so that the bond produced with its use can be machined or stressed already a short time after the application of the polyurethane composition.
