HIGH-STRENGTH FIBER COMPOSITE MATERIAL CABLE DAMAGE EVALUATION METHOD AND DAMAGE DETECTION DEVICE

摘要

[Problem] To provide a damage evaluation technology that is capable of easily and non-destructively detecting and evaluating damage in a high-strength fiber composite material cable. [Solution] The invention is a damage evaluation method for a high-strength fiber composite material cable in which strands (3, 3) comprising electrically conductive high-strength fiber composite material are twisted together in a state of mutual insulation. Taking neighboring strands (3, 3) as a pair, a value having a correlation to the electrostatic capacity of the strands (3, 3) is measured, and the existence of damage is evaluated on the basis of a comparison result for the measured value.
