The Comparison of mechanical properties between vinyl ester-titan and vinyl ester-clay nanocomposites

In this study، various amounts of clay nanoparticles and titan nanoparticles (1، 3 and 5% wt.) were introduced into a vinyl ester resin matrix by high shear mixer. The influence of these nanoparticles on the mechanical properties (tensile strength، tensile modulus، flexural strength، flexural strength and fracture toughness) is investigated. To investigate the structure of nanocomposites، X-ray diffraction (XRD) and transmission electron microscopy (TEM) tests are done. The XRD test shows that the structure of clay-vinyl ester nanocomposites is exfoliated. The results of tensile، flexural and fracture toughness experiments show that clay is better than titan in the improvement of the mechanical properties. Clay- vinyl ester nanocomposite with 1% wt. of clay has the better mechanical properties than others samples.
