【 摘 要 】

Continuous development in transportation sector makes the development of tires a necessity as manufacturers strive to meet increasingly high requirements. This work aims to study the effect of using a pre-tensioning technique to improve the tensile properties of bead ply in rubber tire to enhance performance and increase working life. Pre-tension levels ranging between 0 and 1,250 MPa were applied on single reinforcing wires at room temperature prior to the vulcanization process. The results show that the tensile strength and maximum tensile strain of bead specimens were increased by 86.66% and 14.7%, respectively, as the pre-tension level increased from 0 to 1,250 MPa. The stress strain curves for the specimens showed a large increase in strength with little increase in strain. The modulus of elasticity (Young's modulus) of bead specimens increased by 85.92 % as the pre-tension level increased from 0 to 1,250 MPa.
