Description

A layer of a fiber reinforced composite consists of many plies. For wavelengths of the same order of magnitude as the ply thicknesses, but still much larger than the fiber diameters, the ply interfaces will act as surfaces of reflection and transmission. A thick layer of a fiber-reinforced composite may then be expected to display many of the features of a solid with periodic structuring. For through-the-thickness propagation of time-harmonic mechanical disturbances, these features include passing and stopping bands.
