Abstract :
Simulations of carbon-fiber-reinforced plastics (CFRP) using the finite element method in electromagnetic tomography nondestructive evaluation systems are presented in this paper. Ansoft Maxwell 3D models describing the interaction of the sensors with both unidirectional and cross-woven plate samples are built and analyzed to show the CFRP orientations. A circular sensors array is designed and 400 test holes are punched through the CFRP plate respectively in order to acquire the sensitivity matrix data based on which the image of the plate can be reconstructed. Calculation shows that the proposed method can roughly sense the damaged area.
