选用了一种改性芳香胺来固化ＴＤＥ—８５环氧树脂，得到了一种耐热性、 工艺性及机 械性能都很好的环氧树脂基体，并结合ＦＴ—ＩＲ，ＤＳＣ及凝胶化时间的测试分析对该基体的固化 反应进行了研究．优化了固化工艺制度，并对该基体的Ｔ—７００碳纤维复合材料的性能进行了研 究．实验证明，该基体与碳纤维粘结良好，纤维强度转化率最高可达８６．５％，可用作碳纤维复合材 料湿法缠绕成型用高性能树脂基体．
A modified aromatic amine was chosen to cure TDE-85 epoxy resin. An epoxy resin matrix with good heat resistance, process and mechanical properties was obtained. FT-IR, DSC and gelation The time of the test analysis of the matrix curing reaction was studied. The curing process was optimized, and the properties of T-700 carbon fiber composites were studied. Experiments show that the matrix and carbon fiber bonding well, the fiber strength conversion up to 86.5%, can be used as carbon fiber composite material for wet winding high performance resin matrix.
