On the basis of the piezo effect and conductivity mechanism, a new damping composite of CPE/DZ/VGCF had been developed, the damping property was tested and analyzed in this paper. In order to further discussing the damping mechanism of composites, the dynamic mechanical behavior was tested and analyzed for a frequency of 5 Hz, 10 Hz, 30 Hz, 70 Hz, 100 Hz and a varied temperature from -70 ℃～120 ℃ when electrical conductivity was measured. And the dependence of modulus of elasticity and loss factor on the VGCF content was emphatically analyzed. Especially, the damping mechanism of organic molecular with strong dielectric behavior in the composites was studied.
