As developed the automobile industries, the complex and high performance electric equipment have been embedded into the various parts of automobile, such as the safety sensor, automatic driving module. The antistatic technique should be considered to prevent the malfunction of electric equipment in automobile. To remove the electrostatic in the automobile, the antistatic tire cord can be used as a path for the electrical flow. In this study, the PET cord yarn was coated with the various concentrations of carbon black to improve the electrical conductivity of tire. The electrical path on the surface of carbon black-coated PET cord yarn were investigated by using the SEM. The digital multi meter were used to investigate the antistatic performance of carbon black-coated PET cord yarn. The interfacial bonding properties between the PET cord yarn and the rubber matrix were investigated by the H-pull test with respect to the various concentrations of carbon black in dip-coating solution. |
