Modeling and Simulation of Polymer Nano-Composite to Study Mechanical Properties

Abstract

In the competitive environment of aircraft industries it becomes absolutely necessary to improve the efficiency and performance. Modern aircrafts like Boeing 787 and Airbus A350 comprise of around 50% of composite materials by weight. The performance advantages associated with reducing the weight of aircraft structural elements has been the major impetus for military aviation in composites development. Polymer Nano Composites (PNC) due to low cost, light weight, ease of production and designing of end product polymer material are extensively produced in most of the bulk industrial consumable production. However, the lack in strength and low modulus hinders its utility at high end engineering application due to fatigue and creep failure as compared to metal and ceramics. In order to enhance its properties reinforcement are introduced nano scale to increase is mechanical strength, heat and temperature resistance and decrease in permeability. Nano scale is so small that its visualization and manipulation of properties creates challenges at experimental perspective. Thereby, employing computational approach to develop a structure and examine further how properties varies with change of time and conditions that temperature, pressure, stress and concentration. Modeling and optimization of Polymer Nano Composites, that is, Graphene Nano Sheet with Polyvinyl Alcohol (GNS-PVA) , Graphene Nano Sheet with Polyvinyl Chloride (GNS-PVC) through Simulation Software (Material Studio). Series of simulation shows its Young‟s Modulus has increased to considerable value. By virtue of exceptional properties demonstration Graphene based polymer nano composite are used where high performance and strength desired under extreme temperatures and pressures like aerospace. The increase in Young‟s Modulus is evident as its raise from 67 % up to 124 % with in-cooperation GNS in PVA. Young‟s Modulus value through simulation shows linear increase in Young‟s Modulus is observed with increase of weight percentage of Graphene from 3.5 to 5 weight percent whereas after 5.1 to 6 weight percent the increases in not linear. The maximum achieved value is approximately 124 percent increase. With incorporation of Graphene Nano Sheet in Polyvinyl Chloride the maximum value observed after increase weight percent is 4.42 GPa which is almost 53 percent increase in Young‟s Modulus
