深空探测用柔性太阳毯的制备及性能

Preparation and Performance Evaluation of Flexible Solar Blanket for Deep Space Exploration

面向我国深空探测任务用新型柔性太阳毯,开展了柔性复合材料制备工艺技术、性能评价研究。结果表明,采用模压聚酰亚胺纤维增强有机硅橡胶柔性复合材料,能够满足柔性太阳毯需求。自动涂胶工艺能够实现高黏度硅橡胶均匀薄涂在聚酰亚胺薄膜表面。对比测试表明,硅烷偶联剂能够提高柔性太阳毯的T剥离强度,但使其低温柔韧性下降。

The preparation technology and performance evaluation of flexible composites were studied for the new flexible solar blanket used in deep space exploration missions in China.The results show that the molded polyimide fiber reinforced silicone rubber can meet the demands of flexible solar blanket.The automatic coating process can achieve the uniform and thin coating of high viscosity silicone rubber on polyimide film.The comparative test show that the silane coupling agent can improve the T-peel strength of flexible solar blanket,but reduce its flexibility at low temperature.
