Present study is to fabricate bell structure material which have bell structure pore in its body, and investigate its damping characteristic. First, bell structure materials, which a piece in a pore is ZrO2 ball and matrix is Al alloy, were fabricated by original method. Second, their damping characteristics were investigated by in-house damping evaluation system. As a result, bell structure material presented higher damping characteristic than those without bell structure. Moreover, the damping characteristic increased when the amount of the bell structure increased.
