Study of mechanical performance of polymer nanocomposites reinforced with exfoliated graphite of different mesh sizes using micro-indentation

The first phase of this work aims to use the right additive nano-fillers choices, such as exfoliated Graphite (ExG), increasing mechanical, electrical, and thermal performances. In work, we are interested in quantifying effect particles' size on a polymer matrix's performance. For this, three sets polymers filled with Graphite, characterized by particle sizes, called meshes 50, 100, 150, were investigated. analysis, reinforced subjected indentation tests define local mechanical properties. sample is an epoxy 862 matrix graphite additives. each specific size, additives mixed percentages 0% act control, 0.5%, 4%, 8%, 16% weight. Matching pure polymers, have proven significant improvements elastic properties (such modulus, hardness, stiffness, etc.). Results showed that epoxy's affected percentage nano-additives. Through inspection load-displacement curve, it can be concluded nano-additive has influence plastic sample. Therefore, nanoparticles significantly improved material
