摘　　要：以天然橡胶(NR)和顺丁橡胶(BR)为基料,以短切碳纤维(SCF)为添加剂,制备了SCF/NR/BR复合材料,考察了SCF用量对NR/BR的摩擦性能及力学性能的影响。结果表明,SCF可增强NR/BR基体的强度,增大其硬度。在NR/BR混合胶中加入15份SCF可以降低混合胶的摩擦系数,减少混合胶的磨损量,提高混合胶的耐磨性能。SCF增强的NR/BR在摩擦过程中发生了磨粒磨损和黏着磨损,形成了卷曲磨屑。Natural rubber(NR) and cis-polybutadiene rubber(BR) were used as base materials and short carbon fiber(SCF) was used as additive to prepare SCF/NR/BR composites, and the effects of SCF amount on the friction and mechanical properties of NR/BR were investigated. The results showed that SCF could enhance the matrix strength and hardness of NR/BR. When 15 phr SCF was added into NR/BR compounds, the friction coefficient and wear volume could be reduced, and the wear resistance could be improved. NR/BR composites enhenced by SCF experienced abrasive wear and adhesive wear during the friction process, resulting in the formation of crimp abrasive.
