INVESTIGATION IN TO THE STATIC AND DYNAMIC PROPERTIES OF LIGHTWEIGHT STRUCTURAL SANDWICH PANEL

Abstract

Analytical investigations on the static and dynamic behaviour of light weight structural sandwich panels, which are widely employed in maritime, aircraft, transport, and mechanical/civil engineering applications, are provided. These light, thin-walled structures can vibrate ferociously and are sensitive to even the smallest disturbances. So, the main goal of this work is to improve sandwich panels' static and dynamic behaviour by investigating various face sheets and core materials. Studies on carbon-based polymer nanocomposite are currently generating more interest because to its favourable thermal, electric, magnetic, and structural characteristics. In this study, functionally graded carbon nanotube reinforced polymer composite faces with a 3D graphene foam core and functionally graded carbon nanotube reinforced polymer composite faces were all used to make the sandwich panels. Also, the thermal stresses created in this structure when these panels are exposed to a thermal environment have a significant impact on the dynamic behaviour. Hence, the honeycomb core and polymer composite sandwich panels with reinforced FG-CNT face sheets are examined in various thermal environments. This study examines the properties of forced and free vibration to analyse the dynamic behaviour of a structure
