Abstract

The article treats the possibility of estimation of specific defects occurring in carbon-carbon composite materials by eddy current method of nondestructive testing. With the help of the developed mathematical model of electromagnetic field distribution, there has been analyzed the influence of the range of parameters on the estimation of the defects’ depth including the diameter of the absolute transformer overhead eddy current converter and the frequency of the excitation current on the estimation of the depth of such defects, as well as the influence of the defect orientation relative to the surface. The article analyzes sensitivity of defect depth estimation for different values of excitation current frequency and transducer diameter. The possibility of large defects estimation is confirmed by means of tests on specimens-simulators with kerfs of different depth made of carbon-carbon material.
