2) property conservation percentage
性能保持率
1.
The mechanical properties of T700/epoxy resin composite were equivalent to those of T300/epoxy resin composite before aging,while the former was superior to the latter in respect to the property conservation percentage after aging for 70 d.
结果表明:湿热环境没有改变两种复合材料的破坏模式,但使复合材料的纵、横向压缩强度和剪切强度略有降低;对复合材料/金属胶接结构,湿热老化环境不会导致胶接界面产生损伤,但会使胶接强度下降;老化前两种复合材料的力学性能基本相当,老化70 d后T700碳纤维/环氧树脂基复合材料的性能保持率略优。

补充资料：塑性保持率
分子式：
CAS号：
性质：又称抗氧指数。系生胶试片经140℃×30min老化后的塑性值与塑性初值的比率，用来表示生胶抗氧化能力。是标准胶六项重要指标之一。
