In this study, the neat epoxy and nanocomposites with volume fraction (1, 3, 5, 7 and10%) of nano SiO2 particles reinforced with six layers of chopped mat E-glass fibers (CM) specimens were prepared by molding method. The results of Impact strengths of EP/SiO2 nanocomposites reinforced with 6 layers of CM E-glass fibers showed that Impact strength has a random behaviour with increasing volume fraction of SiO2 nanoparticles. The results showed an increase of Impact strengths with increasing the SiO2 nanoparticles volume fraction at 1% vol. of SiO2 nanoparticles, then decreases with increasing volume fraction at 3% vol. of SiO2 nanoparticles, then the Impact strength increases with increasing volume fraction of SiO2 nanoparticles until the Impact strength reach to maximum values (78.93KJ/m2) at 7% vol. of SiO2 nanoparticles. And then Impact strength decreases with increasing volume fraction at 10% vol. of SiO2 nanoparticles.Also the results of shore D hardness of EP/SiO2 nanocomposites reinforced with 6 layers of CM E-glass fibers showed that Hardness No. an increase with increasing the SiO2 nanoparticles volume fraction at 1% vol. of SiO2 nanoparticles, then decreases with increasing volume fraction at 3% vol. of SiO2 nanoparticles, then the Hardness No. increases with increasing volume fraction of SiO2 nanoparticles until the Hardness No. reach to maximum values (85.03) at 10% vol. of SiO2 nanoparticles.
