Abstract : In this present work, we report the synthesis of RGO-PVDF nanopowder using the classical hydrothermal reaction process at 150°C in one pot followed by polymeric binding with PVA to create a highly elastic piezo-resistive sensing sheet. In this process, scanning electron microscopy (SEM) and X-ray diffraction (XRD) studies were carried out to characterize the morphology of the resulting nanopowder. This sensing sheet is pasted on the upper layer of the glass fibre-reinforced composite (GFRP) produced by the hand lay-up method. The combined manufactured samples were tested on a universal testing machine (UTM) to characterize the mechanical properties of the composite in tension and flexural following ASTM standards. Simultaneously, the change in resistance of nanosensing sheets was also recorded and the data were correlated to determine the properties and response characteristics of the smart RGO-PVDF nanosensor, which has been encountered and verified by using the adequate numerical technique.
