摘　　要：梳理了空间可展结构的分类及发展趋势,从铰接可展结构-带簧铰链、杆状可展结构、面状可展结构及体可展结构四个方面调研了刚性基体高应变复合材料在空间可展结构中的应用现状,从力学和黏弹性特性方面提出了其在可展结构中的应用优势及需要考虑的问题。高模量、低密度、低膨胀系数的刚性基体高应变复合材料是空间可展结构的应用方向,而刚性基体高应变复合材料可展结构的设计方法,以及将其用于大尺寸可展结构的低成本和高精度制造工艺仍有很大的探索空间。In this paper,the classification and development trend of deployable space structures are summarized.The application status of stiff matrix high strain composites in deployable space structures is summarized from four aspects:hinged deployable structures-spring hinges,rod like deployable structures,plane like deployable structures and volume deployable structures.The application advantages and problems to be considered in deployable structures are proposed from the mechanical and viscoelastic properties.The stiff matrix high strain composite with high modulus,low density and low expansion coefficient is the application direction of space deployable structures.However,the design method of rigid matrix high strain composite deployable structures,as well as the low-cost and high-precision manufacturing process for large size deployable structures,still have a lot of space to explore.
