The main thrust of this work was to develop a technique for measuring the anisotropic properties of materials. A low frequency (5MHz) technique was developed using a single transducer similar to the one used in acoustic microscopy, to measure anisotropic properties of ceramic matrix composite (CMC) materials. Experiments were conducted to verify that the velocity of the SAW is a function of the fiber orientation and fiber content of unidirectional CMC. Several important anomalies were imaged and compared to the results obtained from destructive analysis.
