Ultrasonic leaky plate wave propagation in ceramic composite laminates has been investigated using acoustic reflection methods. From ultrasonic measurements on a unidirectional composite plate, experimental velocity dispersion curves for plate wave modes have been constructed. A simple theoretical model has been fitted to the data. The model has been used to estimate some of the unknown constituent elastic constants. Nondestructive characterization techniques, exploiting leaky plate waves in a scanning configuration, are demonstrated. These scans permit the construction of detailed spatial maps of elastic behavior or occurrence of discontinuities in the composite.
