Research Abstract	This study investigates a concept of gossamer adaptive structure systems that have variable geometry characteristics in order to achieve various advanced missions in orbit. We propose the use of shape memory polymers for the adaptive inflatable structures and the variable-length shape memory coil. Furthermore, the deployable composite film structure is proposed that combines the film structures and the actuators developed with shape memory polymers. It is shown that the deployment of the proposed film structure was stable when the shape memory polymer is used as an actuator for the deployment.
