The effect of electron beam on the mechanical and thermal properties of hybrid epoxy/clay/TiO 2 nanocomposites

Abstract

In this research, the effects of electron beam on the mechanical and thermal properties of epoxy resin/clay/TiO₂ nanocomposite were studied. The epoxy/clay/TiO₂ nanocomposite was prepared by dispersing clay and TiO₂ nanoparticles in epoxy matrix. The dispersion of the clay/TiO₂ in the epoxy matrix was characterized by X-ray diffraction and transmission electron microscopy analyses. The obtained results confirm the structure of exfoliate and intercalate in the prepared samples. Mechanical properties and thermal stability of nanocomposites were studied by tensile test and simultaneous thermo-gravimetric–differential thermal analysis. In order to study electron beam irradiation effects, nanocomposites were exposed to electron beam irradiation in 100, 500, and 1000 kGy doses. The results show that mechanical characteristics and thermal stability of epoxy resin/clay/TiO₂ decreased with irradiation.
