| 摘 要： | 以傅瑞德-克拉夫茨(Friedel-Crafts)反应为基础,活化处理Twaron纤维的惰性表面。对经过活化处理的Twaron纤维进行了单丝拔出(SFP)、X射线衍射(XRD)、扫描电镜(SEM)、红外图谱(FTIR)、表面电子能谱(XPS),以及表面自由能等测试。测试结果显示,经过活化处理后,Twaron纤维表面因环氧基团的接枝而使表面自由能显著增加;纤维表面的结晶结构未发生显著改变,纤维的本体强度未降低;相对应的环氧树脂基复合材料的单丝拔出强度提高了约50%。 |

| Abstract: | Twaron fiber surface was modified via a novel chemical approach based on Friedel-Crafts reaction.After the modification treatment,the surface properties were investigated via SFP,XRD,SEM,FTIR,XPS and Surface Free Energy measurement,and so on.The results show that after the treatment,the oxygen/carbon ratio of Twaron fiber surface increases remarkably because of Epoxy group graft,and the crystal structure of Twaron fiber surface was not destroyed,moreover the single fiber pull-out strength value of Twaron fiber/Epoxy composites was enhanced by about 50 %. |
| Keywords: | Twaron fibers interfacial properties Friedel-Crafts reaction surface treatment |
