Thermo-kinetic Properties of Graphite-Enriched vinyl Ester Composites

What is it about?

* The study investigated the properties of composites made from graphite-enriched vinyl ester resin (GVER) with different amounts of graphite micro-platelets (GMPs). * Thermo-gravimetric analysis was used to study the thermal degradation behavior of the composites under non-isothermal conditions. * Various iso-conversional methods, such as Kissinger, Flynn-Wall-Ozawa, Kissinger-Akahira-Sunose, and Tang method, were applied to calculate the apparent activation energy (Ea) of the composites. * The Ea values increased with the addition of GMPs, indicating higher thermal stability of the composites. * The elastic modulus and glass transition temperature of the composites also increased with the addition of GMPs, indicating improved mechanical and thermal properties. * The study provides valuable insights into the thermo-kinetic behavior of graphite-enriched vinyl ester composites, which can be useful for various applications in industries such as aerospace, automotive, and construction.
