Enhancement of Mechanical Properties and Handling Characteristic of Tire Rubber Using Different Percentage of Nano Aluminum Oxide and Carbon Black

Abstract

Rubber based composites are widely used especially in transportation. The goal of the this paper is to study mechanical properties and handling characteristics of rubber based composites of carbon black and Nano Alumina additive (50 nm), then select an optimal composition, then study the effect of adding particle on the cornering stiffness. Carbon black increased mechanical properties and enhanced the handling characteristics as well as Nano Alumina. The wear rate decreased rapidly with increasing nano filler percentage. Post UV (345 nm) laser vulcanization shows improvement in mechanical properties. The optimum values for composite rubber were (2.5% Nano Al2O3 and 60 phr Carbon Black) which gave 800 %, decreasing in wear rate and slipping as well as an increasing about 22% in cornering stiffness of rubber composite, while slight increasing was carried out in hardness of the same composite rubber.
