A method of determining the fiber direction elastic modulus of a thin-ply unidirectional fiber reinforced metal matrix composite using ultrasonic plate waves is described. The results obtained by the ultrasonic technique are compared to values of Youngs modulus from mechanical tests on the same materials. The agreement shows that the ultrasonic method is a reliable and essentially nondestructive way of determining Youngs modulus in thin unidirectionally reinforced metal matrix composites. ultrasonic characterization, graphitealuminum, graphitemagnesium, graphitecopper, boron aluminum, metal matrix composites, nondestructive evaluation.
