Abstract :
The characterization of carbon-fiber-reinforced plastics (CFRP) using multi-frequency eddy current sensors are presented in this paper. Three sensors are designed for bulk conductivity measurements, directionality characterization, fault detection and imaging of CFRP samples. Models describing the interaction of the sensors with the CFRP plate samples are developed to provide explanation and physical insights. A signal processing method is developed to compensate for the variation in lift-off during the measurements.
