| 摘 要： | 分析了用于卫星天线反射器的金属薄膜/复合材料结构在模拟空间环境寿命试验的高低温循环过程中的应力;给出了金属薄膜在经历高低温循环时产生微裂纹的机理。根据微裂纹产生机理,提出了选用合适的过渡层材料在金属薄膜和复合材料基底之间形成应力释放层,抑制金属薄膜产生微裂纹。仿真分析和试验结果均证实了这一方法的可行性,并提出了进一步降低微裂纹产生的措施。

| Abstract: | The thermal stress of metallic film/composite material substrate structure for satellite antenna reflector during high-low temperature cycle is analyzed and simulated in this paper.Samples after high-low temperature cycle was observe and analyzed by microscope,and the mechanism of microcrack formation in the metallic films is also described.An appropriate material was used for forming a stress-releasing layer between metal film and composite material substrate;which intends to release the breaking stress ge... |
