Abstract：A type of composite was made of unsaturated polyester resin(UPR), carbon fibre(CF), and nanosize carbon black(CB). The electrical and basic mechanical properties of the composite with electric field induced and conventional molding was compared and analyzed. The results showed that the conductivity of composite was anisotropic and could be enhanced when the filling amount was appropriate with 0.3V/μm direct current (DC) electric field induced. The best CB filling amount was 0.5phr. At that time, the volume resistivity of composite with CF filling amount was 3,6,9phr reduced 46.8%,29.0%,12.5% at axial direction, and 28.6%,18.8%,8.3% at normal direction of electric field line. Meanwhile, the basic mechanical properties of composite was not changed by electric field induced,and maintained substantially constant.
