Analytical results are presented for the reflection of acoustic waves from liquid‐laminated composite interfaces. The composite is oriented such that the laminates are stacked normal to thex3directions with propagation confined to thex1‐x2plane. The fluid‐composite interface is assumed to be normal tox2. Because of the complex microstructure of composites, continuity conditions exist on both the macro (liquid/composite interface) and micro (laminate interface) scales. Because of the number and nature of these conditions, exact solutions are exceedingly difficult, if not impossible, to obtain. As an alternative, we formulate an approximate analysis in which the composite medium is replaced by a homogeneous, yet dispersive, medium. In the process of replacing the composite with such a material model, the microcontinuity conditions are utilized. Numerical results are presented to demonstrate the dispersive behavior of leaky surface waves on the composite.
