Epoxy resin is very popular polymer as based material in industry and engineering field such for coatings, insulated of electronics circuit, aerospace industry, etc. However, the researchers intensively explored the nanocomposite especially since Toyota Research Group has done research about the nylon-6/montmorillonite system. The combination of mica platelet and Ag nanoparticle is used as filler in this nanocomposite system, and therefore it is known as nanohybrid which is applied in different content to consider its effect to epoxy resin DGEBA properties. The three different content of nanohybrid was proposed to be identified there are 0 wt%, 0.3 wt%, 0.7 wt%, and 1.0 wt% of nanohybrid. The fine dispersion of nanohybrid actually induced the alteration of epoxy resin mechanical properties. The structure of modified epoxy resin is denser than pristine epoxy resin and it increased the hardness properties and tensile strength properties of epoxy resin. However, the frequency and temperature also affected of the epoxy resin thermomechanical properties alteration which the glass transition temperature (Tg) of nanocomposite increased with longer relaxation time. The polymer chains mobility also enhanced related shift factor result of WFL equation with itself motion related its ΔCp.
