Inflatable, Rigidizable Space Structures

Inflatable, rigidizable space structures are transformed from their initially flexible state to one that offers permanent shape-holding and structural integrity through an active rigidization process.  Internal resistive heating was used to induce matrix consolidation and curing of novel, thermoset-coated carbon fiber tows for the purpose of spacecraft rigidization. The ability to dictate this physical transformation through temperature-controlled resistive heating highlights the responsive nature of thermoset polymer composites and demonstrates the advantages of active rigidization. Feedback temperature control was implemented so as to provide a reliable, robust heating method for prescribing material-specific curing profiles.
