摘　　要：采用水煮试验法研究了多孔聚酰亚胺复合保持架材料的耐老化性。试验前后,材料的拉伸强度、摩擦因数无明显变化;红外谱图无显著变化,玻璃化转变温度保持不变;通过TGA、光学显微镜、SEM等检测,未发现材料水解。研究结果表明,多孔聚酰亚胺复合保持架材料的耐水解性较好,环境适应性较好。The aging resistance of porous polyimide cage composite materials is studied by using water boiling test method.Before and after test,the tensile strength and friction coefficient of materials have no obvious change,the FT-IR spectra has no significant change,and the glass transition temperature remains unchaged.The hydrolysis of materials is not found by TGA,optical microscopy and SEM.The research results show that the hydrolysis resistance and environmental adaptability of porous polyamide cage composite materials are good.
