Abstract
The possibility of determining the size of the delamination region and the depth of its location in non-metallic multilayer low-conductivity materials using the developed pulsed eddy current equipment by analyzing changes in the amplitude-time distribution of differential signals along the scan line is provided. A method for obtaining information on the shape and size of delaminations based on the use of a non-stationary thermal method of non-destructive testing is also provided. The effectiveness of the proposed methods for assessing the parameters of discontinuities in composite materials, as well as the productivity of the selected technical solutions is confirmed by the results of experimental studies conducted on samples of carbon fiber composite materials with artificially created structural defects in the form of delaminations of various sizes and shapes.
