Abstract
As we all know that the mechanical characterization of any material plays a vital role in performance of the material throughout its life cycle. One of the major parameters in calculating the mechanical properties of carbon fiber reinforced nanocomposite is glass temperature. Understanding glass transition behaviour of polymer nanocomposites are crucial for optimizing their mechanical properties and performance. We used “Molecular dynamics simulations” to calculate sequel functionalization effect on glass transition behaviour of carbon fiber-reinforced epoxy (LY556) nanocomposites. In this investigation three distinct form of graphene that is pristine graphene, Graphene modified with amine and graphene modified with carboxyl is studied. In this simulation the glass transition temperature (Tg) of pure carbon fiber and epoxy is lower than that of graphene carbon fiber and epoxy composites (GCFEC). The Tg of pristine graphene is higher that of the functionalized graphene and the Tg of graphene functionalized with amine is much higher than that of graphene functionalized with carboxyl group. The results of this simulation are very much close to the experimental results hence this approach can be used to anticipate the glass temperature of epoxy composites. So, from this study it can be concluded that glass transition temperature of carbon fiber reinforced nanocomposites can gives better results on functionalization of graphene.
