Effect of Black Carbon Composition on Hardness, Strength, Wear Resistance and Grip Coefficient of Tire Compound

Abstract

Abstract Purpose: The purpose of this work was to investigate the effect of arrow pattern tire compound on hardness, wear resistance and grip coefficient in dry and wet operation conditions. Methodology: The mixing compound would be consist of Rubber Smoked Sheet (RSS), Styrene Butadiene Rubber (SBR), Black Carbon, Paraffin oil, ZnO, Stearic Acid, Paraffin wax, Epoxy and Sulphur. The compound is mixed and heated to 100°C. After being cooled it is then conducted hardness test, performed wear test and tested for friction. Results: The hardness and the tensile strength of the tire compound increase with increasing black carbon composition. While the wear of the tire compound decrease with increasing black carbon composition. There were no significant differences of grip coefficient when black carbon increased. However, grip coefficient will decrease by 12% when operating conditions change from dry asphalt track to wet asphalt track. Applications/Originality/Value: The life of tire compound usage is increased by the addition of black carbon particles.
