Zusammenfassung:Fiber reinforced plastic products are produced in such a way that there is uniform resin dispersion throughout the product. Fabric is woven on a loom, and the reed dents of the loom are varied from the center to the edges of the fabric so that when the strain in the wrap and weft yarns is released once the fabric is removed from the loom, the fabric has uniform porosity. After removal of the fabric from the loom it is impregnated with a resin, such as epoxy, phenolic, or polyester resins, dried, formed into a desired product shape (as by molding), and the resin is cured. The loom reed utilized to produce the fabric has parallel frame portions with parallel reed wires extending between the frame portions with the dent size larger at edge sections of the reed than at intermediate sections, and with the dent size at intermediate sections larger than the dent size at a central section.
