| 摘 要： | 采用甲苯-2,4-二异氰酸酯(TDI)和环氧树脂(EP)混合制得的表面改性剂对Kevlar纤维进行表面接枝处理,利用扫描电子显微镜观察Kevlar纤维改性前后的表面形貌及改性Kevlar纤维与弹性体间剥离界面的破坏形貌,用衰减全反射傅里叶变换红外光谱仪分析Kevlar纤维改性前后表面化学基团的变化,研究了改性效果和机理。结果表明,TDI和EP发生了化学反应,改性剂可在Kevlar纤维表面引入活性基团,从而显著改善了Kevlar纤维与聚合物基体之间的界面粘合状态。 |

| Abstract: | Toluene-2,4-diisocyanate(TDI) and epoxy resin(EP) were mixed to prepare the surface modification agent and it was used for surface grafting treatment of Kevlar fiber.The surface morphology of Kevlar fiber with or without surface modification and fracture morphology of debonding interface between modified Kevlar fiber and elastomer were observed by SEM.The changes of surface chemical groups between modified and non-modified Kevlar fiber were analyzed by ATR-IR,and the modification effect and mechanism were studied.The results showed that there was a chemical reaction between TDI and EP and the surface modification agent could bring the activate groups into the surface of Kevlar fiber,which could strongly improve the interfacial adhesion property between Kevlar fiber and polymer matrix. |
| Keywords: | Kevlar fiber modification interfacial adhesion TDI epoxy resin |
