| Abstract | ||
| Preparation of epoxy/MgO and epoxy/SiO2 nanocomposites is studding. The nano composites were processed by different nano fillers concentrations (0, 0.01, 0.02, 0.03, 0.04, 0.05, 0.07 and 0.1 wt%). Epoxy resin and nanocomposites containing different shape nano fillers of (MgO:SiO2 composites), are shear mixing with ratio 1:1,with different nano hybrid fillers concentrations (0.025, 0.05, 0.1, 0.15, 0.2 and 0.25 wt%) to preparation of epoxy/(MgO-SiO2) hybrid nanocomposites. Experimental tests results indicate that the composite materials have significantly higher modulus of elasticity than the matrix material but the hybrid nanocomposites have lower modulus of elasticity. The wear rate was decreased in nanocomposites and hybrid nanocomposites than the matrix material and fatigue resistance was increased in nanocomposites and hybrid nanocomposites than the matrix material. | ||
