Future NASA missions in aeronautics and space exploration will require vehicles that are significantly lighter, more durable and have greater functionality than those available today. Advanced materials will play an important role in achieving these goals. New materials must be developed that are lighter in weight and have mechanical (strength, stiffness or toughness), electrical (conductivity, shielding, insulation), and thermal (conductivity, insulation, emissivity) properties that far exceed that of currently available materials. In addition, these applications will demand materials that are self-sensing, self-actuating and self-healing as well as multifunctional. While conventional materials science approaches may answer many of these needs, it is clear that alternative approaches that employ recent advances in nanotechnology and biomimetrics must also be explored. The development of nanostructured materials can lead to systems with significantly enhanced properties over conventional materials. Use of nanostructured materials in aerospace applications can lead to substantial reductions in critical vehicle weight and improvements in durability and performance. Research at NASA Glenn Research Center in the development of nanostructured materials for aerospace power and propulsion systems has led to new materials with considerable promise towards achieving desired weight, safety and performance requirements for future NASA aeronautics and space exploration missions.
