| Abstract: |
| The effects of dynamic fatigue on the adhesion property between steel cords and rubber were investigated. The results showed that， as tensile deformation increased， the adhesion force of steel cords/rubber decreased gradually， and the covered rubber on the steel cord after pull-out appeared to form screw thread patterns. The adhesion force was higher when the screw thread pattern was more distinct. As the bending amplitude increased， the adhesion force of steel cords/rubber decreased slightly ， and the covered rubber on the steel cord after pull-out was not uniform ： less rubber on the stretched side and more rubber on the contracted side. As the parking time extended， the adhesion force increased at first and then decreased， and the maximum value appeared at 32 hours of parking time. |
