Effect of Nano Silica on the Mechanical Properties of Styrene-Butadiene Rubber (SBR) Composite

Abstract

The aim of this research is to study the effect of nano silica which use as a filler with loading level (0.1, 0.3, 0.5, 1, 3, 5, 10, 20, 30, 40 pphr) on mechanical properties of SBR such as Tensile strength, elastic modulus, hardness, abrasion, fatigue and tear resistance. The results show that on addition of small quantities of nano silica an increase of mechanical properties occurs. While at high percent of nano silica aggregation in rubber matrix occurs and decrease themechanical properties.
