摘　　要：采用马来酸酐接枝乙烯-1-辛烯共聚物(MAH-g-POE)及玻璃纤维(GF)对尼龙(PA)66进行共混改性,对共混材料的力学性能和微观结构进行了分析表征。结果表明:POE-g-MAH可改善PA 66/POE、PA 66/GF的界面结合,增强体系的相容性,是PA 66/POE-g-MAH/GF复合材料一种有效的界面增容剂;当PA 66/POE-g-MAH/GF配比(质量份)为65/10/25时,该复合材料的缺口冲击强度为268 J/m,拉伸强度为130 MPa。Nylon 66 was modified with maleic anhydride grafted ethylene - 1 - octene copolymer （MAH-g-POE） and glassfiber （GF）.The mechanical properties and micromorphology of the composite were analyzed and characterized. The results showed that the interracial bond of between PA 66 and POE or GF was improved by MAH - g - POE, and the compatibility of the system was strengthened too. When the mass fractions of PA 66, POE - g - MAH,GF were 65% ,10% and 25% correspondingly, the impact strength and tensile strength of the composite were 268 J/m and 130 MPa respectively .
