Finite element analysis of mechanical and thermal properties of graphe

Defence-related equipment requires certain components which are sensitive to mechanical and thermal parameters. Polyvinylidene fluoride (PVDF) is a semi-crystalline thermoplastic polymer of fluorine. It is known for its piezoelectric properties as well as mechanical strength and has significant applications in various industries like electronics, automobiles, petrochemical, military aircraft, etc. Similarly, graphene has its own fascinating electrical and mechanical characteristics. A composite film made of these two materials in different proportions can be geometrized and simulated for analysis purpose. Recent developments have shown quite significant results; however, considering the two most extreme boundary conditions of high and low temperature; the behavior of mechanical properties in that condition becomes extremely vulnerable. Low-temperature loading finds its use in piezoelectric sensors for aircraft whereas high-temperature loading is the need of the hour in extreme weather conditions for equipment. This paper focuses on finite element analysis (FEA) of this composite material along with its simulation and comparison with its individual elemental properties and brings in significant conclusive applications for its use in the defense sector.
