Epoxy/gamma-Al(2)O(3) nanocomposites were prepared with a homogenizer and followed by a stepwise thermal curing process in this study. The dispersion of gamma-Al(2)O(3) nanoparticles was examined with a transmission electron microscopy (TEM). Meanwhile, the effects of gamma-Al(2)O(3) nanoparticles on thermal, dynamic mechanical and tensile properties of epoxy/gamma-Al(2)O(3) nanocomposites were also investigated and discussed. When the gamma-Al(2)O(3) content was increased from 1 phr to 5phr, results revealed that gamma-Al(2)O(3) nanoparticles were effective to enhance both the stiffness and toughness of epoxy resin. Meanwhile, the maximum properties of glass transition temperature (T(g)), T(d5%), storage modulus, tensile modulus. and elongation at break were observed in the epoxy/5phr gamma-Al(2)O(3) nanocomposite.
