Composites usage according to their properties such as high strength to weight ratio, high resistance to corrosion and their ability to build complex shapes in different industries are increased, but due to their Vulnerability against unwanted impact loads, their usage has been limited. Relatively higher costs of carrying out low velocity impact (LVI) test and data sampling limit due to short experiment time in one side and adaptation of quasi-static impact (QSI) test results with LVI on the other, convinced researchers to use QSI instead of LVI. This research investigated the effect of different percentage of nanoclay (1%, 3%, 5% and 7%) on impact properties of glass-epoxy composite. For this purpose, QSI test was used to forecast this nano-composite’s behavior. To disperse and distribute nanoclay homogeneously inside the resin, mechanical and ultrasonic mixers have been used; EDAX photograph token from nano-resin section confirmed the success of this process. QSI test results showed that adding 3% nanoclay to glass-epoxy composite, increases absorbed energy up to 16% and stiffness up to 12%. It was also determined by perusing SEM photographs that specimens containing 7% nanoclay had a decreased in mechanical properties due to adhesion of nanoparticles.
