摘　　要：分别采用碱、硅烷偶联剂、阻燃剂对剑麻纤维(SF)进行表面处理,采用模压成型工艺制备了SF/酚醛树脂(PF)复合材料。研究了SF表面处理方法对SF/PF复合材料的摩擦磨损性能、力学性能、吸水性的影响,借助扫描电镜观察了复合材料磨损面的形貌。结果表明:SF经阻燃剂处理后,SF/PF复合材料的磨损体积为0.00053cm3,比未处理的SF/PF复合材料减少了77.2%;SF经硅烷偶联剂处理后,SF/PF复合材料的冲击强度、弯曲强度分别比未处理的SF/PF复合材料提高18.7%、15.4%,且耐水性也有一定改善。The sisal fiber （SF） was pretreated by alkali, silane coupling agent and flame retardant respectively. The SF/phenol formaldehyde （PF） composite was prepared by compression molding technology. The effects of treatment methods of SF on frictional and wear property, mechanical property, and water absorption of SF/PF composite were studied, the morphology of the worn surface of the composite was observed by SEM. The results show that： after SF is treated by flame retardant, the wear volume of SF/PF composite is 0.00053 cm3, which decreases by 77.2% compared with untreated SF/PF composite; after SF is treated by silane coupling agent, the impact strength and bending strength of SF/PF composite increase by 18.7% and 15.4% respectively compared with untreated SF/PF composite, and the water absorption of the composite is also improved.
