Air Force Research Laboratory, Materials and Manufacturing Directorate, (AFRL/MLBC), solicits research proposals for "1000 Degrees Fahrenheit Carbon-Carbon Material Development". The principal objective of this effort is to develop an oxidation-protected structural carbon-carbon (C-C) composite for use in environments experiencing temperatures from 1000 Degrees Fahrenheit to 1500 Degrees Fahrenheit. The unique properties of C-C provide enabling material solutions for both aircraft and space launch systems. Applications include heat exchangers, exhaust wash structural aft decks, internal hot structures, turbine and rocket engine components, and thermal protection surfaces. C-C begins to oxidize in air at approximately 750 Degrees Fahrenheit, and as a result its material properties, such as strength and thermal conductivity, degrade. Previous oxidation protection research efforts concentrated on higher temperatures (2600 Degrees Fahrenheit and higher) resulting in protection schemes that are not effective for lower temperature use. This effort concentrates on these lower temperatures and the associated applications. The intended result of the effort is to demonstrate oxidation protection and long term survivability in the 1000 Degrees Fahrenheit to 1500 Degrees Fahrenheit temperatures range for selected applications while maintaining structural and thermal performance.
