We have over 30 years experience designing and developing lightweight multifunctional integrated structural systems for space vehicles and lunar habitats for NASA and aerospace companies. Systems include space frames, foldable plates, composites and laminated inflatable structures. recent developments include designs for re-deployable inflatable structures for the lunar surface addressing the issues of regolith abrasion, folding fatigue, and extreme temperatures and radiation. We have proposed and investigated many applications for these systems.
