Abstract : P13N Polyimide Resin was modified to provide autoclave moldability for boron monofilament and graphite fiber prepregs and to improve the thermo-oxidative stability of composites. It was shown that a modified P13N resin provided autoclave molded boron and graphite reinforced composites which possessed mechanical properties equivalent to press molded P13N composites. Concept validity was determined for improving the thermo-oxidative stability of cured P13N RESIN BY USE OF CROSSLINKING PROMOTER- ADDITIVES. It was established that further developmental efforts are necessary to obtain composites using crosslinking promoter-additives in the resin and also to develop vacuum-bag materials systems for use at cure temperatures greater than 500 F.
