Wear and mechanical prop erties of epoxy/MgO-SiO2 hybrid nanocomposites

Abstract

Preparation of epoxy/MgO and epoxy/SiO2 nanocomposites isstudding. The nano composites were processed by different nanofillers concentrations (0, 0.01, 0.02, 0.03, 0.04, 0.05, 0.07 and0.1 wt%). Epoxy resin and nanocomposites containing differentshape nano fillers of (MgO:SiO2 composites), are shear mixing withratio 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/(MgOSiO2)hybrid nanocomposites. Experimental tests results indicate thatthe composite materials have significantly higher modulus ofelasticity than the matrix material but the hybrid nanocompositeshave lower modulus of elasticity. The wear rate was decreased innanocomposites and hybrid nanocomposites than the matrix materialand fatigue resistance was increased in nanocomposites and hybridnanocomposites than the matrix material.
