The current research aims to develop the mechanical properties by treating the fiberglass with nano materials. The methodology that was adopted can be summarized as prepare the (tensile, impact, and vibration) molds with proper ASTM dimensions by CNC machine, after that preparation of nanoparticle suspension that consists of H2O and (1wt%, 3wt%, and 5wt% SiO2) respectively. Firstly, magnetic stirring was used for mixing H2O and Silica powder for 10 minutes. Secondly, the ultrasonic was used to disperse nanoparticles in water for 15 minutes. The mechanism that was adopted in treating fiberglass was immersion the pieces of fiberglass in nanoparticle suspension for one minute at room temperature and after that heated the fiber at 50C in thermal furnace for 10 minutes to accelerate the drying process, after that drying the fibers for two hours to remove the moisture of fibers. The hand lay up process was used for preparation the samples that fabricated of epoxy and 2layers of E-glassfiber at RT and normal humidity. The control case was the results of samples fabricated of epoxy with fiberglass without treatment with nano silica. The comparison between the results that occurred from the samples fabricated of epoxy and two layers fiberglass that immersed in nanoparticle suspension and the control case to know the development in mechanical properties.The key findings showed that highest value of impact was 36kJ/m^2 in samples fabricated of epoxy and fiberglass that immersed in nanoparticles suspension with 1wt% SiO2 and 99wt% H2O with increasing percentage 43% as compared to control case. The highest value of tensile was 45MPa in control case. The highest value of natural frequency was in samples manufactured from epoxy and 2layers fiberglass treated by 1wt% SiO2 with increasing percentage13% as compared to control case
