Carbon Fiber Reinforced, Zero CME Composites

Technical Abstract: This project proposes to develop moisture insensitive, high performance, carbon fiber laminates for future missions. Current space-qualified resins swell as moisture is absorbed. Eliminating moisture induced swelling (i.e. strain) will permit reallocation of telescope error budget and simplify integration and test activities. A relatively simple laminate production process is envisioned where eutectic alloy will replace traditional polymer resin matrix. In terms of strain, eutectic alloys are insensitive to moisture absorption and possess tailorable properties. Key fiber and alloy adjustments will achieve the best blend between laminate moisture insensitivity, thermal and structural properties.

Telescope metering structures, optical benches, deployable precision booms, and reflectors for astrophysics, earth observing, and planet finding missions including: SAFIR, TPF, ATLAST, SPECS, UVOIR, ACE, and DESDYNI. Ground-based submillimeter telescope truss tubes and primary mirror panels for CCAT.

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.
