TDE—85/芳香胺树脂基体及碳纤维复合材料性能

Study on Properties of TDE -85/Aromatic Diamine Matrix and Carbon Fiber Composites

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．

Through applying a modified aromatic diamine to cure TDE-85 epoxy resin, a formula with high heat resistance, mechanical and processing properties is derived. According to the analysis of FT-IR, DSC and measurements of gel-time, the curing reaction is studied and the curing regulation is also modified. Through the study on the properties of its T-700 carbon composites, the matrix is proved that it can cohere well with carbon fiber and the fiber strength transforming coefficient is high up to 86.5%.
