STUDY THE EFFECT OF STEEL WIRES PRE-TENSION ON THE BENDING AND ADHESION PROPERTIES OF BEAD PLY IN RUBBER TIRES

Abstract

Tires are considered important components of the vehicle by which the vehicle can move on the road. The continuous development in the transportation requires improving tires to suit the modern requirements of the transportation. This work includes studying the effect of using the pre - tension technique to improve the flexural and adhesion properties of bead ply in rubber tires. Pre-tension levels ranging between (0- 1250 MPa) were applied on each single reinforcing wire at room temperature before the vulcanization process. The results showed that the increasing in maximum bending strength, bending stiffness, and maximum shear strength by (26 %) due to pre-tension. The single fiber pull-out test results show that the debond shear strength was increased by (27 %) pre-tension on steel wires.
