Investigated in this paper is a new hybrid cable-wire consisting of outer new Fiber Reinforced Plastic(FRP)and a steel wire as a core. First of all, a design method of cross section of the new hybrid cable-wire is proposed on the basis of the safety factors of 1.7, 3.0 and 1.1 against the yield limit state of the core steel wire, the ultimate limit state of the hybrid wire and the hazard state corresponding to the breaking of the outer FRP by accidents from standpoint of fail safe, respectively. Next, the mechanical properties of carbon-steel hybrid wires are dealt with, which consist of outer CFRP containing parallel carbon fibers and a core steel wire, and are dimensioned by the design method and produced by a method called the pultrusion method for trial. Results of a static tensile test, bending test, lateral pressure test and fatigue test prove the possibility of their application to structural cables and the necessity of further study for developing reliable anchorage systems of hybrid cables. A corrosion test emphasizes the importance of investigation on countermeasures against galvanic corrosion of carbon-steel hybrid wires.
