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.
