Viscoelastic analysis of polymer composites is focused to understand effect of meso-scale structure of composite on the internal friction for application of vibration damping in precision instruments. In this paper, the meso-scale structure of the composite is supposed to be periodically clustered hexagonal array of fibers. Internal damping of the composite is evaluated by energy dissipation in cyclic response. Interaction of fibers and viscoelasticity of the matrix cause the energy dissipation in the composite. To evaluate the damping capacity of the composite in details, a homogenization theory with multi-scale asymptotic expansion is used to analyze meso- and macro-scale behavior of the composite
