Defect characterization in layered composites using a pulsed eddy-current technique

The practical possibility of determining the size of the delamination area and its depth of location in nonmetallic multilayer low-conductive materials is demonstrated using the unique pulsed eddy current equipment facilities. Operational integrity and efficiency of the application of the developed techniques and engineering solutions are confirmed by the results of the experimental studies performed on the carbon-fiber-reinforced plastic specimens with artificial defects in the form of delaminations varying in sizes and shapes.
