In the current research, magnesium oxide nanopowder (n-MgO) was prepared using dry chemistry method. The structural characterization of the prepared n-MgO was carried out using x-ray diffraction (XRD) technique and scanning electron microscope (SEM). The powder was mixed with epoxy resin at ratios of 2%, 4%, 6% and 8%. The effect of reinforcement of n-MgO on thermal properties of epoxy-resin-based composites such as thermal rate and insulation index was studied at three different temperatures: 380, 680 and > 1800 K. Thermal testing that was carried out included thermal conductivity measurement using Mathis TCi and erosion rate test using oxy-acetylene flame technique. The results showed that increasing the content of n-MgO can significantly enhance the thermal properties such thermal conductivity, thermal diffusion, specific heat capacity as well as thermal resistance.
