摘　　要：研究了 T3 0 0 /540 5和 T3 0 0 /HD0 3这 2种先进复合材料在热氧老化中的失重率、力学行为和玻璃化转变温度随老化温度与老化时间的变化。发现它们的热氧化机理包括脱湿、残余低分子组分的挥发、后固化、热分解和物理老化等 。The changes with aging time and aging temperature in weight loss, mechanical properties and glass transition temperature of two types of advanced composites, T300/5405 and T300/ HD03, during thermooxidizing aging were studied. It was found that the aging mechanisms involved may include moisture desorption, evaporation of residual low molecular weight components and post curing, decomposition and physical aging of resin matrix. The effect of each mechanim depends on the aging temperature.
