Polyimide and diphenyl oxide resins were found to provide superior heat resistant plastic systems in the form of glass reinforced laminates and filament wound composites. Glass fabric reinforced polyimide laminates based on Monsantos SKYGARD 700 resin and ironsides diphenyl oxide resin DP 4-94 were measured for flexural strengths. DuPonts polyimide resin PI-3301 was used successfully to prepare filament wound composites, as was the Ironsides diphenyl oxide system DP 4-94. The polyimide and diphenyl oxide resins were measured for flexural strengths. Dupont s polyimide resin PI-3301 was used successfully to prepare filament wound composites, as was the Ironsides diphenyl oxide system DP 4-94. The polyimide and diphenyl oxide resins were selected for future work regarding process optimization and design data generation, as a result of an initial screening program involving fifteen resin systems. Several commercially available glass finishes were examined in combination with the polyimides and diphenyl oxides. None offered significant advantages over others for heat aging in the 600-800 degrees F range. Author, modified-PL.
