摘　　要：以耐高温聚酰亚胺为基体树脂,高硅氧纤维为增强体,采用模压加工方法制备了高耐热树脂基复合材料,使用热失重分析仪、动态热机械分析仪、力学性能测试机和连续太赫兹无损检测系统对所制备的树脂基复合材料进行了耐热性能、力学性能表征和无损检测,研究了复合材料中各组份配比不同对其性能的影响。结果表明,所制备的G2树脂基复合材料性能最佳,内部无明显分层和气孔,并且具有较高的耐热性能以及良好的力学性能。Resin matrix composites with high temperature resistance polyimide as matrix resin and high silica fiber as reinforcement were prepared by moulding.Thermal resistance,mechanical properties and non-destructive testing of resin matrix composites were studied by thermogravimetric analyzer,dynamic thermomechanical analyzer,mechanical property tester and continuous terahertz nondestructive testing system.The influence of the ratio of component on the performances of the composites was studied.These results show that the prepared G2 resin matrix composites have the best performances with no obvious delamination,no pores and high heat resistance.
