The results of Impact strengths of EP/SiO<sub>2</sub> nanocomposites reinforced with 6 layers of CM E-glass fibers showed that Impact strength has a random behaviour with increasing volume fraction of SiO<sub>2</sub> nanoparticles. The results showed an increase of Impact strengths with increasing the SiO<sub>2&nbsp;&nbsp;</sub>nanoparticles volume fraction at 1% vol. of SiO<sub>2</sub> nanoparticles, then decreases with increasing volume fraction at 3% vol. of SiO<sub>2</sub> nanoparticles, then the Impact strength increases with increasing volume fraction of SiO<sub>2</sub> nanoparticles until the Impact strength reach to maximum values&nbsp; (78.93KJ/m<sup>2</sup>) at 7% vol. of SiO<sub>2</sub> nanoparticles. And then Impact strength decreases with increasing volume fraction at 10% vol. of SiO<sub>2</sub> nanoparticles.Also the results of shore D hardness of EP/SiO<sub>2</sub> nanocomposites reinforced with 6 layers of CM E-glass fibers showed that Hardness No. an increase with increasing the SiO<sub>2</sub>&nbsp;nanoparticles volume fraction at 1% vol. of SiO<sub>2</sub> nanoparticles, then decreases with increasing volume fraction at 3% vol. of SiO<sub>2</sub> nanoparticles, then the Hardness No. increases with increasing volume fraction of SiO<sub>2</sub> nanoparticles until the Hardness No. reach to maximum values&nbsp; (85.03) at 10% vol. of SiO<sub>2</sub> nanoparticles.</p> ER -
