| Abstract | ||
| The aim of this research was to study the ability of improving the impact resistance and Vickers microhardness of composite material based on aluminum metal reinforced by 5, 10, and 15wt.% of chopped alumina fibers. Stirring casting method has been used to make composite material by using vortex technique which is used to pull the chopped alumina fibers to inside the melted aluminum and distributed them homogeneously. Regarding the impact test, results shown that the impact resistance of the composite material are more than that in the aluminum metal and these values are increased with increasing of the amount add fibers and they reached maximum values at (10 wt. %). Then they are decreased at (15 wt. %) but these values remain at higher values than that in the aluminum metal. While the Vickers microhardness reached maximum values at (15 wt. %). | ||
