In thermosetting epoxies, thermomechanical properties can be enhanced by conscious selection of curing agents. Full cross-linking leads to a maximum in the glass- transition temperature. However, relation between glass temperature and epoxy matrix depends on several factors beyond degree, such as molecular weight polymers, network organization, amount branching, presence hydrogen bonds. this study, we investigated adding non- stoichiometric ratios resin Epikote 828 agent Jeffamine D230. The investigations were done through combination dynamics simulations experiments, primarily differential scanning calorimetry nanoindentation. Reorganization fewer clusters with higher degree linearity overcomes effect reduction glass-transition increasing concentrations epoxy. elastic, shear, compressive moduli remained constant. Hence, moderating con- tent has potential improve thermal while maintaining mechanical for system.
