We study the effective energy dissipation properties of solid polymer matrixes filled with coated spherical and fibrous inclusions coated with a layer of lossy viscoelastic material. The matrix and the inclusions are assumed to be separated by equal-thickness interfacial layers of a lossy viscoelastic material. We show that the remarkable loss amplification mechanism is operative in such particulate-morphology materials when the effective loss properties of composite can exceed the loss properties of the pure matrix by more than 20 times.
