| Abstract | ||
| This research deals with the study the effect of adding the silica particles and alumina particles separately with different ratio (5, 10, 15, 20, and 25 pphr) on the hardness and wear rate of natural rubber NR and styrene butadiene rubber SBR. The results show that the hardness increases with the increase the loading level of reinforcing particles, while the wear rate decreases with the increase the loading level of the reinforcing particles. The largest value of the hardness and the lowest value of the wear rate were for styrene butadiene reinforced with 25 pphr of silica as compared with natural rubber. Also the reinforcing by SiO2 increases the hardness and decreases the wear rate more than of Al2O3. The results indicated that the hardness and the wear rate for SBR and NR reinforced by SiO2 and Al2O3 at (25 pphr) illustrated in the following table: | ||
