Ramanujam Sarathi – Ravindrakumar Sahu – Michael G. Danikas

   In recent times, epoxy nanocomposites are used as electrical insulating materials. It is essential to understand the mechanical properties of such electrical insulating materials for proper design of insulation structure of power apparatus. Fundamental characteristics of epoxy nanocomposites are analysed through wide angle X-ray diffraction (WAXD) studies. The results of the study indicates that intercalated structures are formed above 5 wt % of clay in epoxy resin. Hydrophobic characteristics are analyzed through contact angle measurement. Characteristic variations in material properties of epoxy nanocomposites due to water ageing are analysed through vibration studies. Vibration test results indicate that natural frequency of vibration and damping factor of the material increases by adding up to 5 wt % of nano clay to base resin.

Keywords: nanocomposites, epoxy resin, insulation, vibration test, contact angle
