Progress in Research on Polyimide Composite Bushings for Aeroengine

Abstract

Properties, research progress and application status of polyimide composite bushings for aeroengine were reviewed. The manufacture technology, performance and applications of graphite filled composite bushings, braid composite bushings and chopped fiber composite bushings were primarily introduced. It is pointed out that low cost, continuous manufacture process, high heat resistance and long-service life will be the main directions of polyimide composite bushings for aeroengine and its materials system in the future.
