Macroscopic loss factor and shear modulus of a sea-island type polymer-based composite is calculated by using the equivalent inclusion method combined with the Mori-Tanaka theorem. The influences of the loss factor and the shear modulus of the particle on the macroscopic loss factors and shear modulus of the composite are examined under the shear applied stress. Consequently, an aspect ratio of the particles influences on both of the macroscopic loss factor and the shear modulus of the composite. Moreover, it is found that an optimum range of shear modulus of the particles exists for the maximum value of the macroscopic loss factor of the composite in the case of any aspect ratio of the particles.
