Research Abstract

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.
