Abstract:
      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.
