The Department of Defense (DOD) is seeking proposals for the development of advanced surface treatments for Astroquartz fibers. The objective of this project is to increase the environmental and thermal durability of various Polymer Matrix Composite (PMC) systems, which include a range of resin matrices from 350 degree Fahrenheit-curing epoxies to advanced polyimides. Astroquartz-reinforced PMCs are widely used in radome applications on aircraft due to their excellent dielectric properties. However, their limited durability can impact their service life and maintainability. The project aims to identify key factors contributing to limited durability, develop optimized surface treatment processes for Astroquartz reinforcements, and develop tailored coupling agents to enhance durability. This is a Direct-to-Phase-II (D2P2) topic, meaning no Phase I awards will be made. In Phase II, the awardee(s) will conduct a comprehensive root cause analysis and develop optimized surface treatment processes or tailored coupling agents. In Phase III, the awardee(s) can pursue commercialization of the technology and scale up production. The contractor must also generate qualification data on the final Astroquartz fabric PMC. The project is open for proposals until June 12, 2024. For more information, visit the solicitation link.
