Abstract
An inflatable structure includes an inflatable membrane with an outer surface, and a skin with a textured space-filling Turing pattern disposed on the outer surface of the inflatable membrane. A variable stiffness filament is coupled to the inflatable structure and the variable stiffness filament has a first stiffness at a first temperature and a second stiffness different than the first stiffness at a second temperature different than the first temperature. An electrical energy source is included and in electrical communication with the variable stiffness filament, and the electrical energy source is configured to apply Joule heating to and increase a temperature of the variable stiffness filament from the first temperature to the second temperature such variable stiffness actively controls a stiffness of the inflatable structure.
