In a recent in-house research program, the damping of twelve continuously-reinforced metal-matrix composite specimens was measured. The data were interpreted in the context of several material damping models, including thermoelastic damping due to transverse thermal currents and microstructural damping via the strain energy rule of mixtures. The reinforcing graphite fibers were found to have a significant impact on composite damping. Much work remains to be done before damping can truly become a design property of structural metal matrix composites, and several avenues for future research and development are discussed.
