摘要
为提高碳纤维／环氧复合材料热氧化性能，采用热失重一差热分析（ＴＧ－ＤＴＡ）研究了稀土盐种类和用量对环氧树脂热稳定性的影响。结果表明，在２５０℃时环氧树脂的热失重近５％，加入０．５％稀土盐后热失重为零。
In order to increase the thermal-oxidation stability of carbon fiber/epoxy composite materials,the effect of type and quantity of rare earth salt on the thermal stability of epoxy resin have been studied by using the thermogravimetric-differential thermal analysis(TG-DTA)technique.The results show that the weight loss is 5 % for pure epoxy resin,and 0 % for epoxy resin mixed with 0.5% rare earth salt at the temperature of 250℃
