The Department of Defense, specifically the United States Air Force, is seeking proposals for the development of advanced surface treatments for Astroquartz fibers as part of the SBIR program. The primary objective is to enhance the environmental and thermal durability of Polymer Matrix Composites (PMCs) used in aerospace applications, addressing issues related to moisture and thermal conditioning that currently limit their service life. Astroquartz-reinforced PMCs are critical for aircraft radome applications due to their superior dielectric properties, and the successful development of this technology could significantly improve maintainability and performance. Interested applicants must demonstrate prior relevant experience and submit their proposals by June 12, 2024, with the opportunity being part of a Direct-to-Phase-II solicitation, which allows for immediate Phase II funding based on previous work. For more details, visit the official solicitation page at DOD SBIR/STTR.
