摘　　要：选取不同短切玻璃纤维(SGF)含量的聚酰胺66(PA66)/SGF复合材料,研究对比PA66/SGF复合材料与热固性环氧树脂基绝缘材料的物理性能、力学性能和绝缘性能。结果表明,随着SGF含量的增加,PA66/SGF复合材料的密度增大,但均低于热固性环氧树脂基绝缘材料标准;弯曲强度、拉伸强度和冲击强度增大,当SGF含量达到20%以上时,复合材料的综合力学性能达到热固性环氧树脂基绝缘材料标准;击穿强度和耐电弧时间增加,优于热固性环氧树脂基绝缘材料标准。因此,PA66/SGF复合材料作为高压开关设备绝缘件材料是可行的,但实际应用还需进一步的工程应用研究。PA66/short glass fiber(SGF)composites with different content of SGF were prepared and their physical prop⁃erties,mechanical properties and insulation properties were investigated and compared with those of the thermosetting epoxy⁃based insulating materials.The results indicated that the density of PA66/SGF composites increased with an in⁃crease in the SGF content,but it is still lower than the standard of thermosetting epoxy⁃based insulator material.The composites presented an increase in bending strength,tensile strength and impact strength of when the content of SGF is more than 20%.The comprehensive mechanical performance of the composite can reach the standard of thermosetting epoxy⁃based insulator material.Moreover,the dielectric strength and arc resistance time of the composites were im⁃proved to be better than the standard of thermosetting epoxy⁃based insulator material.In conclusion,it is feasible to employ the PA66/GF composites as an insulation material for use in HV switchgear.However,an engineering application research is still necessary for the practical application of the PA66/GF composites.
