CA 2472838

Described is a composite material having a flexible synthetic composite matrix, and a textile support web embedded therein. This composite material is characterized in that the composite matrix is based upon a cross-linked polyurethane, in that a textile support web is integrated into the polyurethane composite matrix, and in that a textile patterned surface is formed on at least one side of the polyurethane composite matrix. The textile support web is preferably comprised of a woven fabric or knitted fabric and is expediently arranged centrally within the polyurethane composite matrix. Advantageously, the process for producing this composite material consists in that during the cross-linking of a reactive parent material of a polyurethane, a textile support web is completely inserted into the parent material of the polyurethane matrix, which has been applied to a subcarrier, and a textile patterned surface is bonded to the cross-linking polyurethane layer, as soon as the inner stability will allow an even, single-sided embedding without the material breaking through, after which the polyurethane layer is reacted out. This material is characterized in that it can be bent, folded, and rolled, and can be sewn. It exhibits favorable properties with respect to flammability rating, color fastness, and resistance to fading. The composite matrix based upon a cross-linked polyurethane is preferably formed using a reactive high-solids polyurethane (PUR) system.
