Pull-out analysis of laser modified polyamide tire cords through rubber matrix

The results showed that laser treatment increases the interfacial shear strength of rubber/fiber without reducing strength of cords. Finally, a mechanical model of failure based on pull-out method was used to investigate the effect of laser treatment on the adhesion strength of cord/rubber. Thus, an index of laser intensity was introduced which would be capable of predicting the influence of any laser treatments on interfacial shear strength between cords and rubber.
