利用热熔法预浸料,采用热压罐固化工艺制备了T700S/QY8911复合材料.首先考察了QY8911双马树脂的黏温特性,然后通过表面张力与接触角测定、界面剪切强度测试、吸湿前后玻璃化转变温度测定、复合材料基本力学性能测试及断口形貌分析等方法综合考察了T700S/QY8911复合材料的界面匹配性.结果表明:QY8911树脂在较长的温度和时间范围内具有较低黏度,T700S/QY8911预浸料具有优异的预浸料工艺适用性,其最佳制备温度为90～110℃.T700S/QY8911复合材料界面剪切强度在高温下具有较高的保持率,浸泡360h后的Tg仅比干态下降了19℃,干态/150℃,湿态/20℃及湿态/150℃下层间剪切强度、弯曲强度及弯曲模量保持率均大于50%,且层剪破坏试样纤维与树脂结合紧密.实验结果表明,T700S/QY8911复合材料具有良好的界面匹配性.
