Abstract:

采用改性的单体反应物聚合法(MPMR)合成了一系列低黏度、耐高温异构聚酰亚胺树脂,研究了树脂预聚物分子质量对树脂的高温流变行为、固化后热氧化稳定性的影响,并对树脂的分子结构及其复合材料的加工工艺性能、力学性能进行了表征。结果表明:树脂预浸液常温储存期大于两个月,亚胺化后PI-2纯树脂最低黏度为154Pa·s,固化后树脂质量损失5%的温度大于560℃;石英纤维/PI-2树脂基复合材料在室温和500℃的弯曲强度分别为917、197MPa,弯曲模量分别为29、22GPa,拉伸强度分别为760、341MPa,拉伸模量分别为32、31GPa,压缩强度分别为570、95MPa,层间剪切强度分别为62、10MPa。
