Influence of Alumina and Zinc OxideNanoparticles on The Tensile, Impact and Hardness Properties of Epoxy Nanocomposites

The present work investigates the effect of addition different concentration of nano Alumina (Al₂O₃) and nano zinc oxide (Zno) by (1%, 3%, 5%) weight fraction with epoxy as the matrix on the tensile, impact and hardness properties. Preparing the samples by using hand lay-up technique, magnatic sterrier, vacuum chamber and ultra-sonication method. The results show that there are increases in tensile strength and impact toughness at 3% Al₂O₃ nanoparticles (21%) and (189%) respectively compare to pure epoxy. Due to adding 3% Zno nanoparticles there are increase in tensile strength by (21%) and increase impact strength (28%) compare to pure epoxy. In addition, the hardness improved slightly when increase nanoparticles materials of both components. (paper)
