Mechanical properties of graphene nanoplatelets reinforced epikote 828 under dynamic compression

In this experimental investigation, the influence of graphene nanoplatelets (GNPs) on dynamic behavior polymeric material such as diglycidyl ether bisphenol A (DGEBA) epoxy is investigated using Split Hopkinson Pressure Bar (SHPB). Nanocomposite samples with a different weight percentage GNPs i.e. 0, 1, 2, 5 wt% were fabricated and tested under compression to understand nanofillers mechanical performance epoxy. The results established that changing mass fraction greatly influences confirmed optimal was 1 because good dispersion viscosity. While, further increase in resulted degradation strength agglomeration sheets, porosity, their poor interfacial bonding. Moreover, each nanocomposites at three impact pressures 1.5, 4 bar. main objective quantify effect strain rate resulting damage modes. This study high increases viscosity porosity void structure which generates high-localised stresses into matrix causing premature failure loading.
