摘　　要：采用原位聚合法制备了尼龙6/芳纶纤维(PA6/KF)复合材料。测试结果显示复合材料的拉伸强度从50.4 MPa提高到75.3 MPa,弯曲强度从41.1 MPa提高到72.1 MPa,热变形温度从44.5℃提高到83.1℃,而其冲击强度略有下降。SEM和DMA结果表明:尼龙6与芳纶纤维的界面粘结性好,复合材料的刚性得到提高。Nylon6/Kevlar fiber（PA6/KF） composite was prepared via in-situ polymerization. The results showed that the tensile strength,flexural strength and heat distortion temperature improve from 50.4 MPa,41.1 MPa,44.5 C to 75.3 MPa, 72. 1 MPa,83.1 C respectively,while the impact strength decreased slightly. The results of SEM and DMA showed that nylon6 and Kevlar fiber had strong adhesion in interface,and the rigidity of the composite was improved.
