卫星在轨运行过程中,太阳翼会受到恶劣的低真空、温度等环境因素影响,为了提高太阳翼在轨运行过程中的可靠性,对聚酰亚胺薄膜与太阳翼基板的粘贴技术进行了实验研究。结果表明:对聚酰亚胺薄膜表面进行电晕处理,能够显著地提高其表面粗糙度。聚酰亚胺薄膜与硅橡胶结合力得到大大提高,聚酰亚胺薄膜与基板剥离强度达到8.59N/cm,经过热真空及温度循环实验验证,电晕后的聚酰亚胺薄膜薄膜与基板粘贴牢固可靠,能够适应空间恶劣的环境。电晕技术为聚酰亚胺薄膜与基板的粘贴提供了一种有效的表面处理方法,可以推广至航天器其他舱外部件上使用。
During the orbit operation of the satellite,the solar wings will be affected by bad environmental factors such as low vacuum and temperature.In order to improve the reliability of the solar wing in orbit,the bonding technology of the polyimide film and thesolar wing substrate was experimentally studied.Corona treatment on the surface of polyimide film can significantly improve the surface roughness.The bonding strength between polyimide film and silicone rubber was greatly improved.The peeling strength of polyimide film and substrate reached 8.59N/cm.The thermal vacuum and temperature cycling experiments showed that the polyimide film after corona was firmly and reliably adhered to the substrate and could adapt to the harsh space environment.Corona technology provided an effective surface treatment method for the bonding of polyimide film and substrate,which can be extended to other extravehicular parts of spacecraft.
