The application of an eddy-current test technique for the detection of material flaws in graphite-reinforced aluminum panels is discussed. This particular technique involves scanning the specimen and recording both real and imaginary impedance components of the test coil using a format similar to that of an ultrasonic C-scan. The benefits of this approach are discussed and the results are compared with those of X-radiography and ultrasonics.
