Abstract
Calculated results are presented for ultrasonic wave propagation in fiber‐reinforced composite material containing voids, where the fiber reinforcement is unidirectional. Both elastically isotropic and anisotropic fibers are considered. The propagation direction is taken as normal to the fiber length and expressions are obtained for the longitudinal‐ and shear‐wave velocities as a function of composite void and fiber volume fraction. The results exhibit reasonable behavior and a comparison of calculated data and such experimental data as are available shows fair agreement.Keywords
