| Abstract: |
| The effects of pre-dispersed p-aramid pulp on the processing property of composites，the dispersion of the pulp in the composites，and the brittle-fractured surface of the composites were investigated by adding Kevlar Engineered Elastomer（EE） in neat SBR or carbon black and silica reinforced SBR.The results showed that when the addition level of EE is less than 10 phr，the effect of EE on the Mooney viscosity of the composites is negligible；the dispersion of the pulp in matrix depended on the processing shear stress；the processing technology played an important role in the dispersion of the pulp. |
