Thermal and mechanical properties of current POSS polyimides, as well as details of atomic oxygen erosion studies, will be provided upon request. Edwards AFRL will provide a POSS dianiline monomer if needed. PHASE I: Develop and demonstrate a prototype POSS Kapton polyimide with minimal conductivity of 10^-8 siemens and optical transparency (in the ultraviolet/visible wavelength range) similar to Kapton. Provide 3 (6 in. by 6 i, 2 mil thick) conducting Kapton polyimide films containg 0, 10, and 20 weight % POSS PHASE II: Establish performance parameters through experiments and prototype fabrication of a space grade conducting 10 and 20 weight % POSS Polyimide. Provide physical, optical, and mechanical characterization before and after simulated lower earth orbit and geosynchronous orbit exposure. Deliver 3 films each (25 in. by 25 in., 2 mil thick) of conducting 10 and 20 weight % POSS polyimides. DUAL USE COMMERCIALIZATION: These are improvements of a critical class of materials (polyimides) used in hundreds of military and commercial applications. REFERENCES: 1. Phillips, S. H., Haddad, T.

OBJECTIVE: Develop higher energy density solid propellant ingredients that possess acceptable physical properties for higher performing solid propellants for SC and BMD applications. DESCRIPTION: The DoD requires higher performing solid propellants for use on space access and strategic missile systems. Current energetic ingredients are unable to provide the performance needed to meet the performance goals of the Integrated High Payoff Rocket Propulsion Technology (IHPRPT) Phase III goals. These propellants must simultaneously possess higher energy and density while maintaining acceptable hazard, mechanical, and processing properties. The research areas may include, but are not limited to, the following: identification, synthesis, and characterization of new ingredients (e.g., fuel, oxidizer, plasticizer, binder, and/or burn rate modifiers) to increase
