    摘要: The invention relates to a method for producing a PVC long fibre thermoplastic, in which initially at least one hybrid yarn (3) containing reinforcement fibers (1) as well as plastic material (2) is produced. Said plastic material (2) is selected in such a way that it has a high binding affinity with PVC and in which the hybrid yarn (3) is covered with PVC, preferably in the way of an extrusion method and based on the high binding affinity of the plastic material (2) is internally connected to the PVC covering (6).

    摘要: The invention relates to a hollow-chamber section, in particular a hollow-chamber section for windows or doors, said section comprising an extruded section body (1) which consists of plastic and has a number of hollow-chamber walls (2, 2'), said hollow-chamber walls (2, 2') forming a number of hollow chambers (3). Preferably, some regions of the hollow-chamber walls (2, 2') are fibre-reinforced by means of short fibres (4). Some regions of the hollow-chamber walls (2') are additionally reinforced with long fibres (5), in particular continuous fibres embedded directly in the plastic matrix of the hollow-chamber walls (2').
