Tires operate in challenging environments. Tire reinforcement (cord/fabric) fibers are the dominant reinforcement against external forces on tire with tight bonding to tire rubber, and therefore, their adhesion to tire rubber is a key factor of tire safety. This project was initiated to modify the surface of fibers in order to improve their adhesion to tire rubber, and bonding strength of fiber-rubber composites was the scale to measure the adhesion strength. Former investigators observed characteristic laser-induced structure on synthetic fibers and steel cord surfaces after irradiation, which is considered by us as an advantageous factor in developing bonding strength of fiber-rubber composites. We applied various UV laser treatments on the surfaces of (steel/fiber) cords in order to obtain characteristic structures. Surface modification was observed under scanning electron microscope (SEM). In consideration as factors in bonding strength, mechanical properties of the matrix rubber had been tested in addition to its thermal properties by differential scanning calorimetry (DSC) and filler dispersion properties by atomic force microscopy (AFM). As the main test for adhesion strength, we executed a fiber pull-out test method developed by our research group for bonding strength of cord fibers to SBR rubber as well as silicon rubber in both neat and carbon black filled forms for comparison purpose. Our experiment results revealed better adhesion strength when using silicone rubber matrix
