ABSTRACT:
The weight fractions of the phases of a composite material working specimen are determined nondestructively by first performing a sufficient number of nondestructive and destructive calibration measurements on the properties of calibration specimens. The information learned from the calibration specimens is used in combination with nondestructive measurements of the working specimen to determine the fractions of the phases therein, without damaging the working specimen. In one version of this approach, ultrasonic measurements are used to determine fractions of the fiber and matrix in a nonmetallic composite material.
