| Abstract: |
| In ultra high frequency（UHF）band，the effect of the type and addition level of carbon black on the electric property of tire rubber was investigated experimentally.The results showed that，the electric resistivity of rubber composite was only slightly affected by the type of carbon black and the dielectric property was affected greatly, while the permittivity（ε） and tanδ increased with the increase of the addition level of carbon black. The dielectric property of rubber composite highly depended on the operating frequency，and in the UHF band，ε and tanδ tended to decrease with the increase of frequency. Temperature change could influence the dielectric parameters of rubber composite，but had less influence on tanδ when frequency was over 2 GHz. |
