In order to improve the stability of the rotor and explore new ways to replace traditional dampers， this paper studies the method of embedding carbon nanotube （CNT） short fibers into the rotor blades and enhancing structural damping by utilizing their viscoelastic slip effect. A micromechanical model is established to analyze the CNT viscoelastic slip mechanism. Based on the interface critical shear stress and the applied load， the slip behavior of CNT is analyzed， and an explicit expression between microscopic parameters and macroscopic damping is derived. This model fully considers the influence of key parameters such as geometric parameters and mechanical properties of CNTs on their damping effect. The results indicate that the damping effect predicted by the model is in good agreement with the experimental results. By embedding CNTs， the slip damping of the composite material can be significantly improved， reaching about 11 times the damping of the matrix.
