Preparation and characteristics of an advanced polyester tire cord with hybrid effect

Abstract

Many efforts have been made to study new reinforced materials to meet the increasing demands of various products. Hybrid cords have attracted a great deal of attention due to low cost and incomparable properties. Nylon and polyester are currently two of the most prevalent materials used as tire cords, while how to incorporate both of their desirable properties into one cord has been a meaningful scientific research. In this study, a new advanced polyester tire cord was developed by adopting the design of experiment. Its stress–strain curve demonstrated a high modulus typical for the standard polyester thus improving tire dimensional stability and handling performance and high breaking elongation up to 21.7% that was a favorable characteristic of nylon cord creating a hybrid effect. H-adhesion experiment showed that this advanced cord had comparable adhesion to rubber as the standard polyester tire cord and could be used for production of tires.
