This study considers the scattering of P and SV waves in SiC fiber-reinforced Al composite with interfacial layers. The fibers are assumed to be parallel to each other and randomly distributed with a statistically uniform distribution. We assume same-size fibers and same-thickness layers with nonhomogeneous elastic properties. The scattering of time harmonic P and SV waves by a cylindrical inclusion with a nonhomogeneous interface layer is analyzed and the results of the single scattering problem are applied to the composite medium. Numerical values of scattering cross-sections, phase velocities and attenuations of coherent plane waves, and effective in-plane elastic constants are obtained for a moderately wide range of frequencies. The numerical results show significant dependence on parameters containing fiber volume fraction and interface properties.
