Abstract:When the spacecraft is running on the geostationary orbit (GEO), due to the influence of high energy electron radiation, the surface and depth of dielectric material would be charged. Electrons will accumulate in high resistivity dielectric materials and are hard to release, which affect the normal operation of the spacecraft seriously. Based on the dielectric material theory and taken a method for modification by adding ZnO micron filler into epoxide resin (EP) body, this paper developed a new kind of modified EP composites with non-linear conductivity. The electrical test and breakdown test under strong electric field were then carried out. Experimental results show that the modified ZnO/EP material has excellent nonlinear-conductivity characteristics. The current density of 1% ZnO/EP sample is the largest, and 5% ZnO/EP sample is minimum respectively under the same electric field. When the electric field is more than 20kV/mm, the current density increases exponentially with increasing the electric field. The DC breakdown voltage of modified material also remain unchanged, and the sample of 5% filler content has the highest DC breakdown strength but smaller dispersion.
