对 HKT800碳纤维表面形貌、元素、官能团等进行了表征分析；对 AG80环氧树脂配方体系进行了优化；然后对 HKT800碳纤维/AG80环氧树脂复合材料的力学性能及界面情况进行了测试分析.结果表明,HKT800碳纤维具有比较高的表面活性,表面元素的 O/C、N/C 比例分别达到了25．2％,4．5％,活性与非活性碳原子之比达到0．91；质量比为100∶30∶3时, AG80/DDS/BF3.MEA 树脂体系能够在150℃的工艺条件下固化；HKT800碳纤维/AG80环氧树脂复合材料0°拉伸、弯曲和压缩强度分别达到2682,1874和1639 MPa,层间剪切强度为110 MPa.
The surface topography,elements,functional groups of HKT800 carbon fiber were characterized,the recipe of AG80 epoxy resin was optimized,then the mechanical and interface performance of HKT800 carbon fi-ber/AG80 epoxy resin composite were analyzed.The results showed that:the ratio of O/C and N/C in surface elements reached 25.2% and 4.5%,the ratio of active carbon atoms was 0.91,so the surface activity of HKT800 carbon fiber was higher.The epoxy resin could be cured at 150 ℃ when the mass ratio of AG80,DDS, BF3 .MEA was 100∶30∶3.The tensile,flexural and compression strength of HKT800 carbon fiber/AG80 ep-oxy resin composite were 2 682,1 874 and 1 639 MPa,interlayer shear strength was 1 10 MPa.
