On the basis of the piezo effect and conductivity mechanism, a new damping composite of CPE/DZ/VGCF has been developed, the damping property has also been tested and analyzed in this paper. In order to further discussing the damping mechanism of composites, the dielectric behavior is tested and analyzed in the frequency range 1 kHz^1000 kHz and in the temperature range from -50 ℃~120 ℃. And the measurement of DSC is carried out for a varied temperature from -70 ℃~130 ℃, when the electrical conductivity is measured. Especially, the damping mechanism of organic molecular with strong dielectric behavior in the composites is ascertained.
