説明
CFRP laminate is very sensitive to the impact. Even a low impact creates a delamination and results in the deterioration of the structural reliability. In our previous study, electric resistance change method (ERCM) and two-stage electric potential change method (two-stage EPCM) are proposed to monitor the delamination in the CFRP laminate. ERCM is suited to be applied to the part of the structure where the high accuracy of estimation is required. On the other hand, two-stage EPCM is suited to be applied to the large structure or the part which required rapid monitoring. In this paper, asymmetrical dual charge EPCM is newly introduced. The method can reduce the number of electric charges compare to the ERCM and show fine estimation throughout the object although two-stage EPCM shows poor performance near the center of the charged electrodes. The proposed method is, therefore, to be a standard of the delamination monitoring methods which utilize the electrical property of CFRP laminate. FEM analyses and experiments are conducted in this paper. As a result, the applicability of the method to the practical use is confirmed.
