Research progress and application of polyimide based composites in aeroengine were reviewed. The performance of PMR polyimide composites and its application in areoengine were introduced

and the preparation process

characteristic products and research advance of polyimide composite bushing were discussed. It is pointed out that the trends of polyimide composites for aeroengine in the future are of lower cost

higher heat-resistance

improved processing stability

and the establishment of polyimide database.
