Abstract:The curing reaction kinetics of an eutectic aromatic amine/ epoxy resin E44 system is investigated by
nonisothermal DSC method. The kinetic parameters of this system are calculated by Kissinger, Ozawa and Crane equations:
the apparent activation energy E =49. 2 kJ/ mol(by Kissinger and Ozawa methods), the reaction order n =
0. 95(by Crane equation), the frequent factor A =2. 60×105 s-1(by Kissinger method). The kinetic model of the curing
process based on n order reaction equation is established, which is used for modeling the curing reaction characteristics.
The curing conditions are defined as follow: 50℃ /2 h, 140℃ /2 h, post-curing 200℃ /2 h. The curing behavior
of the system is hardly affected by the change in the amount of the filler boron carbide (B4C) added into the
eutectic aromatic amine/ epoxy resin E44 system.
