| Outline of Final Research Achievements |
The aim of this study is to develop a novel concept of adaptive structure systems by using shape memory polymers as the structural materials. The results obtained through this study are summarized as follows. Firstly, the use of a pre-elongated shape memory polymer element was proposed and verified in laboratory experiments to show its ability reduce the slack and wrinkled area of flexible thin membrane space structures such as solar sails. Secondary, the painted heater on the surface of the shape memory polymer elements was studied to show its effectiveness to efficiently and uniformly heat up the temperature of the elements above its glass transition point. Further, it was shown that the heater layer did not affect the capability of the shape recovery of the element by tuning the thickness of the layer but slightly change the visco-elastic properties, which must be considered when the elements are subjected to dynamic force.
