In this paper, the influence of dispersion methods on dispersion degree of nanoc1ay in epoxy matrix was studied. The dispersion degree of nanoc1ay was evaluated by various, method, namely XRD, viscosity measurement and TEM techniques. The results showed that high speed stirring (2000 rpm) may create the interchalated structure of nanoclay in matrix: the d-spacing of 128E increased from 23.33 A to 38.02 A, and for 130E from 26.71 A to 40.12 A after 10 hours stirring. The combination of high speed stirring with ultra sonication still more increases the dispersion efficiency: the d-spacing of both studied nanoclay was increasing almost 2 times. The presence of nanoclay increased fracture toughness of nanocomposites compared to neat epoxy.
