Abstract:
Due to the electrical anisotropy of carbon fiber reinforced polymer （CFRP）， this paper presents a method to inverse the anisotropic conductivity of unidirectional CFRP laminate using eddy current testing （ECT）. The relationship between the conductivity and probe signal of ECT is studied by means of numerical simulation. Finally， the accuracy of inversion result is improved by optimizing the initial conductivity by use of experimental data.
