The possibilities and limitations of eddy current methods for the inspection of carbon fiber-reinforced plastics have been investigated. The present investigation was undertaken to gain a better understanding of the possibilities and the limitations of eddy current methods for the inspection of CFRP tube. The main objective of this study is to evaluate the investigation of ECT for the inspection of defects containing saw-cut and circular hole in CFRP tube using the LeSATA<SUP>TM</SUP>. This research was carried out to characterize the ECT effect on the defect-shapes such as the saw-cut and the hole ones of CFRP tube and on the ratio of the defect-depth (20%, 40%, 60%, 80%, and 100% depth to the thickness of CFRP tube) and conclusions were obtained. 1) For the self-manufactured CFRP tube, the inspection of the defect between 100Hz and 1kHz was not possible and it had nothing to do with the defect-shape. The high frequency such as 100kHz~500 kHz made the inspection of defects possible. 2) The different 3-D pictures was obtained by the direction of axial and circumferential saw-cuts that have the same shape. The fact that both the sum of magnetic vector potential and the interference components were considered for the circumferential one, made them exaggerated. 3) While the depth of the defect was increasing, the phase angle was lowering and the amplitude of EC was gradually increasing. Therefore, while the lower amplitude of EC made the permeable depth of the signal deeper, it made the sensitivity of the defect lower.
