Completed TRL 4 (started at 3, targeting 4)
Develop a technology to form low cost; high-precision mirror assemblies from Amorphous Metals: Take AMs from TRL-1 to TRL-3 in FY12,Fabricate a reproducible isogrid backing from AM; Form a near-optically smooth surface with curvature in a one-step casting process; Develop a composite with a controllable CTE by adding negative CTE second phase particles; Investigate casting methods (forging, casting, etc.), Develop new IP on materials and processes, Engage with industry to work towards scale-up.
This RT&D project could revolutionize the way small mirrors are fabricated for spacecraft (JPL, NASA, commercial or military). Amorphous metals can be formed into atomically smooth mirrors with the correct curvature in a single casting step (little or no polishing). High stiffness, low density isogrids can be cast (nearly impossible to replicate with a different metal). AM composites can be designed to have controllable CTE. AM's are perfect for optical mechanisms (due to their elasticity) and can be joined seamlessly. AM coatings have excellent reflectivity and are scratch resistant
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
