Functionalized CNTs for Composites with Little to No Resin

Completed TRL 2 (started at 1, targeting 2)

Description

In this work, CNTs functionalized with thermally labile groups will be used to fabricate composites containing little to no polymer resin.

Benefits

Fabrication of complex composite structures exhibiting CNT-like mechanical properties would allow for lower scrap and reducing part count. Additionally, the achievement of CNT-like properties in these structures would reduce vehicle weight resulting in fuel savings and increased cargo personnel carrying capability. By using CNTs modified with thermally labile groups, composite fabrication would not be limited to traditional flat panels as with CNT tapes/sheets but be expanded to making complex structure thereby opening the design space.

How to get involved

This is early/mid-stage (TRL 2) — 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.
