Description:
6F-Polyimides with a phenylethynyl endcap (HFPE) were fabricated into carbon fiber composites using the standard polymerization of monomer reactant (PMR) approach via ester/acid route. Composites made from T650-35 carbon fabrics were evaluated at 600-700 F for their physical and mechanical properties as well as thermo-oxidative stability. In addition, concentrated HFPE monomer solutions were infused into stitched AS4 and T650-35 preforms to improve the composite performance under thermal cycling and rapid heating conditions.
