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.
