Abstract

The continuous development in transportation sector makes the development of the tire a necessity to suit the modern requirements of transportation sector. This work aims to study the effect of using pre-tension technique to improve the flexural and adhesion properties of bead ply in rubber tire that enhances its perpormance and increase its working life. Pre-tension levels ranging between (0 - 1250 MPa) were applied on each single reinforcing wire at room temperature before vulcanization process. The results showed that the increasing in maximum bending strength, bending stiffness, and maximum shear strength was (26 %) due to pre-tension. The single fiber pull-out test results revealed that the debond shear strength was increased by (27% ) pre-tension on steel wires .
