摘　　要：国产CCM40J-6K高模碳纤维基板的空间高低温热循环耐受性是决定其是否可以大规模应用于空间太阳电池板的关键因素,必须解决交变热环境下的面板与电池电路的匹配性和长寿命问题。本文以国产CCM40J-6K高模碳纤维/环氧复合材料的太阳电池板为研究对象,开展了热循环环境适应性试验研究,分别从国产和进口碳纤维基板适应高低温交变能力对比、国产碳纤维基板铺设电池电路后适应热环境能力以及电池板在轨寿命等3个方面进行测试试验。结果表明:国产碳纤维CCM40J-6K所构成的电池板综合性能与进口M40JB-6K相当,CCM40J-6K基板与三结砷化镓电池片匹配性良好,国产碳纤维电池板经疲劳热循环后的开路电压和短路电流的变化率分别为0.55%和0.24%,太阳电池片和玻璃盖片外观完好无损,太阳电池电路与基板聚酰亚胺面保持绝缘,且碳纤维表面无脱粘现象。说明国产碳纤维CCM40J-6K能够应用于太阳电池板研制。The spacial thermal-cycle tolerance of the substrate based on domestic high-modulus carbon fiber(CCM40J-6K)was a key factor that determine whether it can be applied to solar cell panels on a large scale,and the matching between the panel and the solar cell and the on-orbit service life for solar cell panel in the alternating thermal environment must be solved.The solar cell panel based on domestic high-modulus carbon fiber/epoxy composite of CCM40J-6K was taken as the research object,and the test research of thermal-cycle environmental adaptability was carried out.In this paper,tests had been carried out from three aspects:the comparison of domestic and imported carbon fiber substrates for adapting to the capacity of high and low temperature alternating,the ability of domestic carbon fiber substrates to adapt to thermal environment after laying solar circuits,and the on-orbit service life of solar cell panels.The test results show that the comprehensive performance of the solar cell panel based on domestic carbon fiber CCM40J-6K is comparable to that of the imported M40JB-6K.The CCM40J-6K substrate has a good matching with the triple-junction GaAs solar cell.The change rates of open-circuit voltage and short-circuit current of solar cell panels based on domestic carbon fiber after fatigue thermal cycling are 0.55%and 0.24%,respectively.The appearance of the solar cell and cover glass is intact,the solar cell circuit is insulated from the polyimide surface of the substrate,and the surface of carbon fiber has no debonding phenomenon.It shows that the domestic carbon fiber CCM40J-6K can be used in the development of solar cell panels for solar array.
