Epoxy resins are very used thermoset polymers because of their good combination of high elastic modulus and mechanical strength and good chemical and thermal resistance. One of their main limitations, the low

The conventional DSC has been extensively employed for studying the glass transition and crystallization. However, many metallic glasses have very small

nonisothermal (dynamic). The basic assumption for the application of DSC technique to the cure of the thermoset polymers is that the rate of the kinetic process (dα/d t ) is proportional to measured heat flow. The cure kinetics of uncatalyzed thermosetting

and vitrification. Gelation is the incipient formation of a cross-linked network, and it is a most distinguishing characteristic of a thermo-set. Gelation does not usually inhibit the process of curing, and it cannot be detected by techniques which are
]. Glass transition temperature ( T g ) is also a characteristic of each material, specially thermoset polymers. By definition, it is the temperature which defines when the polymer chains or network start their movements and it is the transition of a rigid
