Ultra-Lightweight Nanocomposite Foams and Sandwich Structures for Space Structure Applications

Microcellular nanocomposite foams and sandwich structures have been created to have excellent electrical conductivity and radiation-resistant properties using a new method that does not involve or release any toxicity. The nanocomposite structures have been scaled up in size to 12×12 in. (30×30 cm) for components fabrication. These sandwich materials were fabricated mainly from PE, CNF, and carbon fibers. Test results indicate that they have very good compression and compression-afterimpact properties, excellent electrical conductivity, and superior space environment durability.
