NIPPON GOMU KYOKAISHI, 1994 圧電セラミックス粒子と導電粒子を充てんした高分子複合材は, 新しい制振機構を有する制振材料である. 新しい機構に加えて, この複合材は, 高分子粘弾性や粒子間内部摩擦による従来の粒子充てん高分子制振材料の特性も有している. 圧電制振効果と呼ばれるその新しい制振機構は, 複合材中の圧電性と消費回路に由来するものである. 圧電粒子に伝達された振動エネルギーは, 圧電効果によって電気エネルギーに変換され, 導電粒子間の導電路を通りジュール熱に変わるというものである. 本研究では, 制振性能と複合材の弾性率との関係を議論した. この制振材料の圧電効果は, 複合材中の振動伝達効率に関係する. 圧電粒子の粒子径を変化させて, それぞれの制振性能と複合材の弾性率を測定した.
