The present study investigated the mechanism for enhancing the functionality (shape fixity and shape recovery) of shape memory polymer (SMP) composites, as potential candidates for new structural materials applied to space deployable structures, using experiments and micromechanical analyses. Especially, through deployment tests under a thermomechanical cycle, the relationship between fiber architecture and deploymentperformance was clarified, and basic knowledge was obtained for mesoscale material design of optimal functionality. Since the functionality is closely related to fiber elasticity and temperature-dependent characteristics of the polymer, the micromechanical mechanism gained from the aspect was also clarified using thermomechanical finite element analyses.

本文通过实验和细观力学分析，研究了形状记忆聚合物（SMP）复合材料作为空间可展结构新型结构材料的增强功能（形状固定性和形状恢复性）的机理。特别是通过热机械循环下的展开试验，阐明了纤维结构与展开性能之间的关系，为优化功能的细观材料设计提供了基础知识。由于功能性与纤维弹性和聚合物的温度依赖性密切相关，因此还使用热机械有限元分析阐明了从这方面获得的微观力学机制。
