Abstract : Techniques were developed for fabricating carbon fiber composites using a Naval Ordnance Laboratory developed high temperature resin, phenylated polyquinoxaline (PPQ). Composites with interlaminar shear and flexural strengths about 80% of those for similar epoxy composites were obtained. Heat aging at 343 deg C (650 deg F), in air, revealed excellent initial strength retention at temperature but significant loss of strength after 168 hours.
