讨论了氰酸酯树脂、环氧改性氰酸酯树脂、环氧树脂及其M40J碳纤维复合材料耐水性能.考察了几种体系的吸水率、吸水前后力学性能变化,并通过SEM分析其微观状态变化.结果表明,氰酸酯及其改性体系具有低的吸水率,力学性能无明显变化,复合材料吸水率低于浇铸体,拉伸模量、剪切强度有一定程度下降,分析认为主要是由复合材料界面破坏引起的.

In this paper, cyanate ester, epoxy modified cyanate ester, epoxy resin and M40J composite's properties of water-enduring at 100℃ were studied. The analysis of the rate of water uptake and the changes of mechanical properties before and after immersion was reported. It was found that cyanate ester and its modified system owned lower water uptake and had no apparent changes on mechanical properties. The rate of water uptake of composite is lower than that of the cast, but the tensile modulus and shear strength descend. The main reason is the interface is destroyed.
