摘要:

柔性复合材料壳面可在一定曲率半径范围内弹性弯曲收纳,展开后具有一定的自支撑能力,可为星载可展开天线研制提供新型解决途径。随着高应变薄壁碳纤维复合材料结构的发展,关于柔性壳面可展开天线的应用研究日益增多。综述了几类典型柔性壳面可展开天线反射面实现形式,分析了影响柔性壳面可展开天线发展的关键技术,为该类型天线反射面的研制提供了参考。

Abstract:

Thin-walled shells made of flexible composites can be folded in a small radius with its elasticity, and can bear small compression load once deployed. These features enable these structures to be used for some certain spaceborne reflectors. Deployable reflectors made of flexible composites shells have received intensive research with the development of high strain thin-walled composites. Several typical reflectors made of flexible composites shells are reviewed in this paper, and the key technologies needed for the development of the flexible shell deployable reflectors are analyzed.
