The environmental adaptability for porous polyimide cage materials is studied by using high temperature aging ex-periments.The results show that the tensile strength,impact strength and friction coefficient of materials have no obvious change,the IR spectra keeps unchanged before or after aging,and the glass transition temperature stays the same.The ther-mal stability and environmental adaptability for porous polyamide cage materials are good.
