摘　　要：采用熔融挤出工艺制备了尼龙(PA)6/环氧树脂(EP)/LiCl/SiO2复合材料。研究了EP的含量对PA6/EP/LiCl/SiO2复合材料的结晶行为、力学及加工性能的影响。研究发现,随着EP含量的增加,复合材料的结晶度降低、结晶不完善程度增大、PA6结晶受限,PA6/EP/LiCl/SiO2复合材料的拉伸强度、缺口冲击强度、弯曲强度总体上表现出先增大后减小的趋势,而熔体流动速率呈先减小后升高的趋势。当EP含量为3份时复合材料的拉伸强度、缺口冲击强度和弯曲强度均达到最大值,分别为94.68 MPa,11.5 kJ/m2和135.36 MPa。PA6 / EP / LiC1 / SiO2 composites were prepared through melting extrusion process. The effect of EP contents on the crystallization behavior, mechanical and processing properties of the composite were studied. The results show that with the increase of EP content, crystallinity of the composite decreases, incomplete crystallization degree increases, the crystallization of PA6 is restricted, and tensile strength, notched impact strength, bending strength of the composite first increase then decrease, melt flow rate of the composite first decreases then increases. When EP content reaches 3 phr, the tensile strength, notched impact strength and bending strength of the composite reach maximum（94.68 MPa, 11.5 kJ/m2 and 135.36 MPa）.
