Abstract EN
New types of piezoelectric damping materials, including carbon nanotubes (CNTs)/lead magnesium niobate (PMN)/epoxy (EP) resin, are developed.
The tan δ area (TA) analysis method is selected to evaluate the damping properties which obviously clarifies the effect of maximum loss factor (tan δ) and effective temperature range on damping properties.
Furthermore, the dominant factor of damping enhancement is quantitatively analyzed via the value of TA.
Compared with PMN, the interfacial friction of CNTs acts as the dominant factor for the content less than 0.6 wt.%.
The maximum damping percentage of CNTs reaches 29.14%.
CNTs form loop circuits gradually with the content of CNTs increasing, and electrical energy generated via piezoelectric effect of PMN is efficiently dissipated through the conductive network.
Thus, PMN becomes the dominant factor as the content of CNTs exceeds 0.8 wt.%, and the damping percentage reaches 47.43% at the content of CNTs of 1.0 wt.%.
