摘要
研究了应用于航天器表面的环氧树脂材料在不同温度时的表面带电程度,通过设置不同的束流密度,研究了温度、电子束流密度变化对环氧树脂表面充电水平的影响。 结果表明: 在243~363 K温度范围内,当束流密度为0.5 nA/cm2、1 nA/cm2时,环氧树脂表面充电平衡电位均呈现先降低后升高再降低的趋势;束流密度为2 nA/cm2时,环氧树脂表面充电平衡电位变化幅度不大。可见小束 流时温度对表面充电平衡电位的影响更大;束流密度越大,温度对充电的影响越弱,因此表面充电平衡电位越稳定。
Abstract
Surface charging level of epoxy resin materials applied to spacecraft surface at different temperatures is investigated. By setting different beam density, effects of temperature and electron beam density change on surface charging level of epoxy resin are investigated. Results show that when the beam density is 0.5 nA/cm2 and 1 nA/cm2, the surface charging balance potential of epoxy resin shows the trend of decreasing first, increasing and then decreasing in the temperature range from 243 K to 363 K. When the beam density is 2 nA/cm2, the variation range of surface charging balance potential of epoxy resin is not big. It can be found that when the beam density is small, effects of temperature on surface charging balance potential are stronger. The greater the beam density is, the weaker the effect of temperature on surface charging balance potential will be, so the surface charging balance potential of epoxy resin is more stable.
