Determination of Isothermal Cure Kinetic parameters of Epoxy/ 1,8- Naphthalene Diamine/ Barium Carbonate Composite

Epoxy resins are the most important class of thermosetting resins that find application in surface coating, composite matrices, adhesive,encapsulation of electronic components, and aerospace industries. [1] .The kinetics of the curing of epoxy resin has been widely studied with isothermal and dynamic differential scanning calorimetry (DSC). DSC which measures the heat flow from the reacting system are extensively used to study curing reactions [2]. During curing, epoxy resins display extensive branching, passing through the gel point before the formation of macromolecular structures. In this study we have reported kinetic parameters on the epoxy /1, 8-diamine naphthalene/ barium carbonate composite cured under isothermal conditions.
