| Abstract: | A new damping composite of CPE/BaTiO3/VGCF has been developed on the basis of the piezo-effect and conductivity mechanism. The conductivity of composites varied with the VGCF content are tested and analyzed. The results indicate that the conductivity of composites grows up slowly as the VGCF content is in the range of 10%-20%. It is very useful for industrial application to control the conductivity of composites by adjusting the VGCF content. In addition, at the range of - 50 - 1201, the dependence of loss factor on the VGCF content varied with the temperature are tested and analyzed by dynamic mechanical and dielectric behavior measurement of the composites, and expected results are obtained. |
