A Comparison of Ultrasonic and Mechanical Test Values of the Principal Young's Modulus of Unidirectional Metal Matrix Composites,
Abstract
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 Young's modulus from mechanical tests on the same materials. The agreement shows that the ultrasonic method is a reliable and essentially nondestructive way of determining Young's modulus in thin unidirectionally reinforced metal matrix composites. ultrasonic characterization, graphite/aluminum, graphite/magnesium, graphite/copper, boron aluminum, metal matrix composites, nondestructive evaluation.
