The concept of 3-D cylindrical deployable structures could be an effective technology in extreme environments such as outer space. These forms have the advantage of being able to be deployed in three dimensions, but on the other hand, there are still issues related to the thickness of the material when it is made into an actual structure. This study examines the behavior of 3-D cylindrical rigid deployable structures proposed in 2018, which is not affected by thickness, during the deployment process. Through these experiments, we will clarify problems during deployment behavior and study detailed form design for actual use.
