Self-deployable structures for advanced space applications: analysis, design and small scale testing

The aim of this PhD project is to evaluate, design, manufacture and test Self- Deployable structures using a Shape Memory Composite (SMC) technology to be used on advanced space applications, including both small and large space structures such as solar sails, antennas, solar panels and de-orbiting systems. This technology can also enable innovative missions from debris capture to solar system exploration and more. In particular SMPs based mechanisms are here proposed, and feasibility is demonstrated by means of experimental tests targeted to show their suitability to space applications. After a review on space mechanisms and SMC applications, selected designs have been proposed and test campaigns have been performed, including material characterization and the deployment of small scale prototypes. Even if this is only a starting point, achieved results are in accordance with literature and provide an original contribution to the self-deployable structures for space applications.
