A study was conducted to determine the effect of processing parameters on the processability and properties of autoclaved fiber reinforced PMR Polyimide composites. Composites were fabricated from commercially available graphite fabric and glass fabric PMR Polyimide prepreg materials. Process parameters investigated included degree of resin advancement, heating rate, and cure pressure. Composites were inspected for porosity by ultrasonic 'C' scan and photomicrographic examination. Processing characteristics for each set of process parameters and the effect of process parameters on composite mechanical properties at room temperature and 600 F are described.
