A phononic composite material providing structural strength and blocking the propagation of elastic waves over a frequency range referred to as the bandgap. In one embodiment, the phononic composite material consists of a plurality of periodic units, each of which includes a central fiber, a relatively soft interface layer surrounding the fiber, and a matrix layer surrounding the interface layer. The properties of the interface layer may be adjusted, e.g., by adjusting the temperature of the phononic composite material, to transition from a state with a bandgap to a state lacking a bandgap.
