<p>Flat textile article employed as intermediate product for manufacturing moulded bodies with the use of heat and pressure. In accordance with the invention the flat textile article, which consists of a flexible and flat support, for example of a fabric of glass fibre yarns used to reinforce moulded bodies, and of a polymer layer deposited on the support and bonded to the latter, exhibits the following characteristics: the polymer employed, for example a thermotropic polymer, is spinnable and is in the form of fibres and/or filaments which have a diameter of 0.5 to 30 mu m; the said fibres and/or filaments are obtained by the spinning technique using blowing of molten polymer, with the aid of a spinning head, and are extruded directly onto the support, the minimum distance between the polymer exit channel or channels of the die and the support being 10 mm; the layer of polymer fibres and/or filaments is bonded to the support, the separating force being at least 3 cN/cm. The flat article according to the invention can be converted into different moulded bodies, for example into fenders for motor vehicle construction.</p> |
