<p>PURPOSE:To impact lightweight properties while enhancing rigidity and strength by forming an Ni plating coating layer to the outer surface of each high strength steel wire. CONSTITUTION:A large number of high strength steel wires 7 are arranged in parallel to each other at a predetermined interval so as to form a plane and integrated by a resin 8. A reinforcing sheet material 6 is wound around a rod main body 5 so that the longitudinal direction of the high strength steel wires 7 becomes almost parallel to that of the rod main body 5 and fixed by an adhesive. An Ni plating coating layer 9 is formed to the outer surfaces of the high strength steel wires 7 at this time. This Ni plating coating layer 9 is plastically processed at the same time when cold wire drawing processing is performed after the plating treatment of the wire material. The high strength steel wires 7 are formed by employing low carbon two-phase structure steel filament having a wire diameter of 100mum or less and tensile strength of 300 or more and the cross-section of said filament is formed into an oval having long and short diameters.</p> |
