摘　　要：选用TDE-85和E-51作为主体树脂,制备了一种T700碳纤维复合材料,并对这种复合材料进行耐湿热老化研究,分别测定其抗剪切强度、抗拉伸强度及模量和玻璃化转变温度随老化时间的变化值。结果表明,该T700碳纤维复合材料耐湿热老化性能较好,其力学性能在2 000 h的老化过程中变化不太大,但是其玻璃化转变温度值降低很多。One kinds of T700 carbon fiber composite is produced with TDE-85 and E-51 epoxy resin, resist to thermal and wetting aging research on this composite is also done. Gauging the shear strength, tensile strength and modulus, glass transition temperature of the composite and their change during the aging test. The results shows this kinds composite is resist to thermal anti wetting aging, its mechanical properties change little in this test, but its glass transition temperature declines a lot during aging test.
