碳纤维增强树脂基复合材料的热失重特性研究

Study on thermogravimetric characteristics for carbon fiber reinforced resin matrix composites

在实验室研究了两种典型的树脂基复合材料T30 0 / 540 5和T30 0 /HD0 3热老化过程中的热失重特性 ,得到了几种不同温度下两种树脂基复合材料的热失重 时间曲线及失重速率 时间曲线。由此定性地分析了温度、时间对树脂基复合材料热失重特性的影响 。

Thermogravimetric characteristics were researched in lab for two styles of carbon fiber reinforced resin matrix composites(CFRRMC) under thermal aging. Curves of thermogravimetric(TG) and thermogravi metric speed(-dTG/dt) vs time at several temperatures were obtained respectively. Subsequently, effects of temperature and time on thermogravimetric characteristics were analyzed qualitatively. Consequently the threshold temperature was determined, at which thermal aging under control of physical aging transformed into another one under control of chemical aging.
