| Abstract: |
| The effect of epoxidized natural rubber（ENR）dosage on the properties of natural rubber
（NR）/ENR composites was studied. The results showed that after ENR and NR were blended，the maximum
damping factor（tanδ） and damping temperature range（tanδ＞0. 3） of the NR/ENR composites increased，
and the temperature corresponding to the maximum tanδ moved to a lower temperature. As the dosage of
ENR increased，the shore A hardness，tensile strength and elongation at break of the NR/ENR composites
tended to decrease，and the modulus at 100% elongation showed an increasing trend. When the ENR dosage
was 10 phr，the temperature corresponding to the maximum tanδ of the NR/ENR composites was around 25
℃，and its comprehensive properties were the best. |
