| Outline of Final Research Achievements |
We proposed shape memory polymer composite systems with an embedded heating mechanism, and demonstrated that deployment properties can be controlled through temperature distributions applied to the materials, using experiments and finite element analyses. The systems utilized viscoelastic properties (temperature-dependent properties) of fiber-reinforced shape memory polymer composites that change their shapes by heating. We experimentally showed that deployment ratio and time changed depending on heating patterns, and established a method to predict deployment properties with consideration of deployment time as well. Moreover, we presented numerical simulations based on shell elements employing three-layer models which allowed us to analyze deployment dynamics with high precision considering the properties of thin composite materials.
