Abstract

Styrene butadiene rubber (SBR) and natural rubber (NR) composites reinforced with alumina (Al2O3) and precipitated silica (SiO2)particles had been prepared separately by calendaring process.It had been studied the adding effect of the alumina and silica particlesseparately at different ratio (5, 10, 15, 20, and 25 pphr٭) on the tensile characteristics ofnatural rubber NR and styrene butadiene rubber SBR. The results show that the tensilecharacteristics increase with the increase loading level of the both reinforcing particles.The maximum values of the tensile characteristics were for natural rubber as comparedwith styrene butadiene rubber, and the reinforcing effect of silica particles higher than of alumina.The results indicate that the maximum tensile strength at break, modulus of elasticity, and elongation percentage at break were (70MPa, 18, 350%) respectively for natural rubber reinforced with(25 pphr) of SiO2.
