The overall objective of this study is to expand the performance space of carbon-fiber reinforced polyimide composites using a synergistic combination of hybrid inorganic-organic, nano-structured chemicals and state-of-the-art oligoimide chemistry. The addition of nano-structured chemicals both retains the light-weight nature of organic polymers and imparts substantially improved erosion resistance to high energy atomic oxygen and vacuum ultraviolet radiation, as well as high temperature mechanical performance and oxidative stability. In particular, this study will formulate hybrid, nano-structured polyimide composites, from the molecular to the macroscopic level, while tailoring their properties to the service durability requirements of Air Force-related applications.
