In this study, The relationship of between the load stress and number of cycles (S-N curve) about Carbon Fiber Composite Cable (CFCC) are obtained by fatigue testing of repeated tensile cycles. The strain in 4 edges points of thimbles of both ends, that are assessed with strain gauges. In S-N curve behavior, CFCC is fixed in number of cycles to failure of load amplitude about 65 kN. Breaking point of CFCC is edge of thimble in both ends.
