| 摘 要： | 采用阴离子接枝法对Kevlar纤维（KF）进行改性.利用偏光显微镜研究了未改性Kevlar纤维（KF0）和改性Kevlar纤维（KF1）增强尼龙6复合材料的结晶情况，界面横晶的形成机理及影响因素.结果表明，在尼龙6/ KF复合体系中，KF0和KF1的加入都能诱发其表面的基体PA6形成横晶，在低温下纤维的诱发横晶能力小，形成的横晶不致密、不完整;在高结晶温度Tc下形成的横晶完整而致密，纤维的诱发横晶能力大;KF1与基体有较强的结合力，故其诱发横晶能力较KF0强。

| Abstract: | In the paper,Kevlar fiber was modified by anionic grafting of nylon 6.The mechanism and influence of transcrystallization in raw Kevlar fiber reinforced nylon6 copmposites(PA6/KF0)and modified Kevlar fiber reinforced nylon6 copmposites(PA6/KF1) were studied by PLM,so did the crystallization instance.The results show that both KF0 and KF1 can do crystalline nucleation to matrix,and form interfacial transcrystallization;At certain situation,the nucleation of KF increases with temperature,that is to say,higher temperature contributes to forming compact and integrated transcrystallization;Because the modified Kevlar fiber adjoins the matrix well,its nucleation is stronger than that of the raw Kevlar fiber. |
