THE TECHNOLOGY:

Inventors at the NASA Langley Research Center have developed a new UV (ultraviolet)-curable polymer carbon fiber composite and the origami-based deployable structures that are made from the new composite. The new composite and associated origami deployment system were developed for use in stronger, more reliable deployable space structures. These structures include beams for deployable habitats, booms, solar array frames, and antenna supports among others. The polymer shape memory effect allows the origami composite structures to be stored in a small, lightweight package and deployed on-site (i.e., in orbit, on the moon, etc.) through heating. The origami-based composite assemblies outperform other composite-based deployable structures in strength, are lighter than metals, are not susceptible to gas leaks like inflatable structures, and do not require motors to deploy.

Deployable space structures often rely upon telescoping or folding structures that either must be manually deployed or deployed by attached motors. These structures are often made from heavier (relative to carbon fiber composites) metals to provide enough strength to support a load. As such, there is a need for in-space structures that are lightweight, can be packaged compactly, and can be deployed easily. The composite material developed here does not require high temperature baking to cure the polymer, rather relying on UV light to solidify the polymer component. The composite is then included into origami-based structures that can fold and deploy using the polymer shape memory effect. The composite is first trained to assume the deployed structural shape when heated; it is then folded like origami and frozen into the packaged shape for storage and launch. Combining the composite material with the origami-inspired design leads to high strength structures (can hold at least 600 kg on Earth). To date, a ~5-inch prototype structural bar has been produced using the UV-curable composite and further development is on-going at NASA Langley. The deployable origami composite structures are at technology readiness level (TRL) 4 (component and/or breadboard validation in laboratory environment) and are available for patent licensing.
