Abstract
An inflatable for an evacuation system may comprise a nano-fiber material defining an inflation chamber. The nano-fiber material may include a nano-fiber fabric formed of woven nano-fibers, an interior thermoplastic polymeric coating formed over a first side of the nano-fiber fabric and oriented toward the inflation chamber, and an exterior thermoplastic polymeric coating formed over a second side of the nano-fiber fabric and oriented away from the inflation chamber.
