title = "Shape recovery performances of a deployable hinge fabricated by fiber-reinforced shape-memory polymer",
abstract = "A new type of fiber reinforced thermoset styrene-based shape-memory polymer composite (SMPC) is developed and analyzed. The main objective is to systematically characterize the shape recovery properties of SMPC, which is a foundation for SMPC used in deployable structures. Firstly, the deployment dynamics of cured SMPC shell is presented. Then, the shape recovery performance is investigated by finite element analysis (FEA). The deployment process of curved SMPC shell (from 0-180 degree) is simulated by the geometrically nonlinear analysis. The deployment moment increases with the increase of the thickness of curved shell, and the strain show somewhat uniform in the central part of the curved shell. Furthermore, a hinge made of SMPC is fabricated, which consists of two curved SMPC shells in opposite directs. The deployment of hinge can be achieved in about100s by applying a 20V voltage. The deployment ratio approaches approximate 100 \%. Finally the deployment of a prototype of solar array actuated by the hinge is demonstrated.",
