Graphene Nanoplatelets Reinforced Epoxy Composites for Aerospace Application: A case study for Thermal Behaviour

A study was conducted to examine the effects of graphene nanoplatelets (GNPs) on the thermal characteristics of polymer nanocomposites, which are extensively utilised in packaging, biomedicine, and microelectronics. Following ASTM guidelines, samples of GNPs and epoxy were made by shear mixing and solution compounding. Thermo Gravimetric Analyzer (TGA) and Differential Scanning Calorimetry (DSC) were used to examine the samples' thermal stability and glass transition temperature. The results showed that weight retention improved with increasing graphene content, while the addition of GNPs considerably improved thermal properties. As the GNP content increased from 20% to 30%, the glass transition temperature (Tg) climbed from 50°C to 53°C. This study provides important information for material developers by highlighting the possibility for enhanced thermal performance of graphene-dispersed polymer nanocomposites.
