Temperature Effect on Surface Charge of Epoxy Resin

Abstract

Abstract: To study the charge level of epoxy resin material applied to the surface of the spacecraft at different temperature, by setting different beam density, the effect of temperature and electron beam density on the surface charge level of epoxy resin was studied. Experimental results show that, in the temperature range of 243 K to 363 K, when the beam density is 0.5 nA/cm2 and 1 nA/cm2, the surface charge balance potential of epoxy resin showed the trend of decreasing first and then increasing and then decreasing. When the beam density is 2 nA/cm2, the range of surface charge balance potential of epoxy resin is not big. So, when the beam density is small, the effect of temperature on the surface charge balance potential is stronger. The greater the beam density is, the weaker the effect of the temperature on the surface charge balance potential, so the surface charge balance potential of epoxy resin is more stable.
