This paper describes that the influence of filler condition on dynamic behavior of rasin. Mica is used as filler to the epoxy resin. The influence of the perticlue size and concentration of mica is investigated. As the results, the natural frequency and damping ratio of the structural vibration mode is affected by the filler condition. And the influence of filler is different in each vibration mode. Especially, the higher mode influenced by filler condition. Additionally, there is the optimal filler condition which can add both high damping and stiffness. Thus for achiving high stiffness and damping, the filler conditon is the key factor.
