| Abstract: |
| The influence of maleic anhydride modified liquid polybutadiene（MLPB）on the properties of short aramid fiber（SAF）reinforced natural rubber（NR）composite were investigated.The results showed that NR was collaborative reinforced by SAF and carbon black，and the interface bonding between rubber matrix and fiber，static and dynamic mechanical properties were improved obviously by adding MLPB.With the addition level of MLPB increasing，the modulus at 100% elongation increased，the tensile strength，elongation at break and tear strength of the composite were the best when the addition level of MLPB was 4.5 phr. |
