| 中文摘要: |
| 采用机械共混法制备碳化硅（SiC）/氟橡胶（FKM）复合材料，SiC添加前用偶联剂KH560进行表面改性，研究改性SiC用量对SiC/FKM复合材料性能的影响。结果表明：随着改性SiC用量的增大，SiC/FKM复合材料的硬度增大，拉伸强度在一定范围内得到有效提升，阻尼性能和耐液体介质性能略有降低；当改性SiC用量为15份时，SiC/FKM复合材料具有良好的加工性能、物理性能、阻尼性能、热稳定性和耐液体介质性能，综合性能较优异。 |
| 英文摘要: |
| In this study，Silicon carbide（SiC）was modified by coupling agent KH-560，the SiC/
fluororubber （FKM） composites were prepared by mechanical blending，and the effect of the modified
SiC amount on the properties of the SiC/FKM composites was studied. The results showed that，with the
increase of the modified SiC amount，the shore A hardness of the SiC/FKM composites increased，the tensile
strength was effectively improved within a certain range，while the damping property and liquid medium
resistance were slightly reduced. When the modified SiC amount was 15 phr，the SiC/FKM composite had
better processability，physical properties，damping property，thermal stability and liquid medium resistance，
showingexcellent overall performance. |
