Weakening the deformation behaviors on contact interfaces or improving the damping property of polymer matrix composite is conducive to reducing or eliminating friction-induced vibration behaviors. A new high-density polyethylene (HDPE) matrix composite consisting of tetra-needle-like ZnO whiskers (T-ZnOw) and multi-walled carbon nanotubes (MWCNTs) was fabricated. The friction and vibration experiments illustrated that T-ZnOw clearly weakened the deformation behaviors, meanwhile MWCNTs embowed polymer with good damping property. Hence, MWCNTs jointed with T-ZnOw could reduce frictional force and enhance vibration absorbing ability, finally keeping the stability of the contact interface and reducing the friction-induced vibration behaviors. It would help in understanding the synergistic effect of MWCNTs and T-ZnOw on vibration behaviors and developing novel composites with low friction and high damping properties.

减弱接触界面的变形行为或提高聚合物基复合材料的阻尼性能有利于减少或消除摩擦引起的振动行为。制备了一种由四针状 ZnO 晶须 (T-ZnOw) 和多壁碳纳米管 (MWCNT) 组成的新型高密度聚乙烯 (HDPE) 基复合材料。摩擦和振动实验表明，T-ZnOw 明显削弱了变形行为，同时 MWCNTs 使聚合物具有良好的阻尼性能。因此，多壁碳纳米管与 T-ZnOw 结合可以降低摩擦力并增强吸振能力，最终保持接触界面的稳定性并减少摩擦引起的振动行为。
