If successful, the proposed self-healing polymer technology would greatly increase the damage tolerance of current FRP composite materials as well as future, next-generation polymer nanocomposites. The resulting increase in composite durability would greatly increase the structural efficiency of vehicle designs as well as increase their overall lifetime. Ultimately, the proposed technology would allow for reductions in weight for space exploration vehicles thereby reducing the cost of space exploration (i.e., due to reduced launch costs). Beyond NASA, the proposed technology could see use in virtually any large-scale, structural composite application where damage tolerance is of great concern. Potential applications include commercial and military satellites and aircraft, military naval marine vessels, wind and water turbine blades, automobiles and sporting goods among many others. Improvements based on the proposed technology would allow reductions in component mass (i.e., due to increased structural efficiency) as well as reductions in maintenance costs thereby increasing the commercial viability of the target application.
