Research Progress of Oil-Bearing Materials for Porous Polyimide Cages
With the progress of science and technology,aerospace technology is developing rapidly,so there is an urgent need for oil-bearing with long life,high precision and high reliability.Porous polyimide materials not only possess excellent high and low temperature resistance,radiation resistance and good mechanical properties of polyimide,but also have the advantages of self-lubrication,light weight and low density of porous materials,which are widely used in aerospace and other fields.Therefore,the working characteristics,research status and existing problems of porous polyimide oil-bearing materials are systematically introduced in this paper,so as to provide reference for further research of porous polyimide oil-bearing materials.
