Tensile and Electrical Measurement Data for Improving the Mechanical and Electrical Properties of PES Resin EG Composites

Electrical and tensile measurements for PES resin composites containing expanded graphite (EG), ultrasonicated EG, and vacuum processed EG. This is an updated version of the data published in https://doi.org/10.5281/zenodo.15092846 and later versions which were modified as data was processed further. The density normalised tensile data and simulation results were added to the latest version and data relevent to another mansuscript was removed.
