| 摘 要： | 研究了WBS-3环氧树脂固化体系的反应特性,分析了该固化体系浇铸体的性能;并以碳纤维(T-700S)为增强材料,采用手糊成型螺栓加压工艺制备了WBS-3/T-700S复合材料,研究了复合材料的常温力学性能、高温力学性能、水煮后力学性能和动态力学性能,并对弯曲断面进行分析。研究结果表明,WBS-3树脂基体黏度低、适用期长且韧性好,适合于手糊成型、缠绕成型等低成本制造工艺;由此制得的WBS-3/T-700S复合材料具有优良的力学性能和耐高温性能,其弯曲强度为1434MPa,拉伸强度为1972MPa,剪切强度为76.1MPa,玻璃化温度(Tg)超过210℃;该WBS-3/T-700S复合材料具有很好的界面粘接性(树脂对纤维的浸润性良好)、较低的空隙率且纤维分布均匀。

| Abstract: | The reaction characteristics of WBS-3 epoxy resin curing system were studied,and the casting performances of curing system were analysed. With carbon fiber(T-700S) as enhanced material,the WBS-3/T-700S composite material was prepared by hand-paste molding and bolt press technology. The mechanics performance at room temperature,mechanics performance at high temperature,mechanics performance after boiled and dynamic mechanics performance were studied and the crimped section was analysed for WBS-3/T-700S compo... |
