摘　　要：研究了纤维体积比对三维编织芳纶纤维增强尼龙(简称K_(3D)/PA)复合材料力学性能的影响。同时,研究了γ射线辐照处理对K_(3D)/PA的影响。研究发现,随着芳纶纤维体积比的增大,K_(3D)/PA的力学性能提高;芳纶纤维经γ射线辐照处理后,表面含氧量有所提高,并出现新的官能团。纤维经表面处理后,K_(3D)/PA的弯曲强度、弯曲弹性模量及剪切强度均比未处理的高,但冲击强度较低。The influence of fiber volume fraction on the mechanical properties of K3D/PA and the effect of Kevlar fiber surface treatment by y-ray on K3D/PA were studied. The result shows that the mechanical property of K3D/PA increases with the increase of Kevlar fiber volume fraction, the content of oxygen on Kevlar fibers treated by y-ray increases, and the flexural strength, the flexural modulus and the shear strength of K3D/PA treated by y-ray are higher, but the impact strength is lower.
