Abstract: Epoxy resins are used as Lightweight Automotive components, hydrophobic coating, corrosive-resistant thermosetting linings, and other applications. To understand the effect of epoxy resin with Graphene(G)-red Lead oxide (Pb3O4) filler with the application of heat, the thermal behavior of the hybrid composite material is studied in detail. Microstructure characterization of the produced composites had performed employing EDX and SEM. Analyses of the epoxy matrix microstructure have confirmed a relatively uniform distribution of fillers. TGA, DSC, and Longitudinal heat flow methods, were used to determine the thermal behavior of prepared materials by ASTM standards. Heat resistivity and Thermal conductivity of the material increase by adding 0.5 wt% of G initially increase but decreases with an increase in the density of the composite. Specific heat capacity and CTE increase with density for hybrid material. A decrease in Diffusivity indicates a proven thermally insulating material. A simple method adopted for fabrication tends to reduce cost. Epoxy-based Graphene-red lead oxide with modified properties has proven to be a good insulating material.
