采用双螺杆挤出机制备了玻璃纤维（GF）增强尼龙6（PA6）复合材料，系统地研究了GF质量分数对PA6/GF复合材料的力学性能、热性能、密度、吸水性和加工流动性的影响。结果表明，PA6/GF复合材料的冲击强度、拉伸强度、弯曲强度、弯曲模量、密度和热变形温度均随着GF质量分数的增加而增加，而吸水率和熔融指数随着GF质量分数的增加而减小。形态结构显示，当GF质量分数为30%时，GF在PA6基体中得到了有效的包裹和分散。

Glass fiber (GF) reinforced nylon 6 (PA6) composites were prepared with a twin?screw extruder. The effects of GF mass fraction on the mechanical properties, thermal properties, density, water absorption and processability of PA6/GF composites were systematically investigated. The results show that the impact strength, tensile strength, flexural strength, flexural modulus, density and thermal deformation temperature of the composites increased with the increase of glass fiber content, while the water absorption and melt flow rate decreased with the increase of glass fiber mass fraction. The morphology showed that the GF was effectively wrapped and dispersed in the PA6 matrix when the GF mass fraction was increased up to 30%.
