In this method, polyethylene fibers are elongated by 850%˜1,200% and are exposed to a radiation of 2.5˜3.5 Mrads, thus being cross-linked. The first surface of a fabric sheet, made of the polyethylene fibers, is exposed to a voltage of 20,000˜25,000 V while passing over a plurality of rollers, thus being modified at the first surface. A first matrix sheet, melt-extruded at a temperature of 300° C.˜380° C., is formed on the modified first surface of the fabric sheet, prior to an integration of the first matrix sheet with the modified surface of the fabric sheet. The integration is accomplished by a first elastic roller and a first cooling roller. The second surface of the fabric sheet is processed in the same manner as that described above. A second matrix sheet is layered on the modified second surface of the fabric sheet, thus forming a fabric-matrix layered body.

Abstract: A method and apparatus for applying an extrudable material to a substrate, in which a concentrated light beam is directed onto the substrate before or after the application of the extrudable material. The energy of the beam is concentrated on the substrate surface, wherein it is subsequently transferred to the extrudable material deposited on its surface, thereby increasing the temperature and lowering the viscosity of the closely situated material so as to facilitate material penetration into the substrate. This method allows the use of illumination of modest energy density, of wavelengths absorbed by the extrudable material, or of such cross-sectional extent that it may not be transmitted through the extrusion device by which the extrudable material is deposited.
