In this article, the influence of nanoclay Closite 30B on the tensile, the flexural and the punch properties of 2D woven Glass/Epoxy laminate composite have been investigated experimentally. The glass/epoxy/nanoclay laminate have 12 layers and 50% fiber volume fraction is manufactured by VRTM method. Fibers have a plain‐weave configuration with density of 200 g/m 2 , while the nano‐epoxy resin system is made of diglycidyl ether of bisphenol A (Epon828) resin with jeffamine D400 as the curing agent and an organically modified modified montmorillonite in a platelet form, namely Closite 30B. The nanoclay is dispersed into the epoxy system in a 0, 1, 2, 3, 5, and 7% ratio in weight with respect to the nano‐matrix. The results have shown that the maximum improvement in the tensile strength, the failure strain, and toughness are 13, 7, and 27%, respectively, by 7% nanoclay and in the modulus is 9% by 3% nanoclay. The results of three bending flexural test indicate that the maximum improvement in the flexural strength and flexural modulus are 11 by 3% nanoclay and 48 by 5% nanoclay, respectively. Moreover, the result of punch tests have shown that the maximum improvement in energy absorbed is close to 46 by 5% nanoclay for crosshead speed of 1mm/min and close to 23 by 3% nanoclay for crosshead speed of 100 mm/min.
