The Department of Defense, specifically the United States Air Force, is seeking proposals for the development of a fiber/filament capable of withstanding extreme combustion environments, specifically temperatures of 3000°F for at least one hour, as part of the SBIR program. The objective is to create a resultant fiber/filament that can be fabricated into rope seals, which are critical for high-performance hypersonic flight and propulsion systems, where existing materials fall short. Proposers are required to provide detailed reports on their approach, including previous experimental results, and must demonstrate the feasibility of their solutions through rigorous testing and documentation. The solicitation is set to open on May 28, 2025, with proposals due by June 25, 2025, and further details can be found at the provided source link.
