Non-isothermal curing kinetics of Tung-maleic anhydride and epoxy resin

The non-isothermal curing kinetics of Tung-maleic anhydride and epoxy resin E-51 blend with 1% DMP-30 by weight was studied by Malek method.The real curing process was stimulated well using mechanism equation estak-Berggren.The active energy calculated by iso-conversion ratio method was 69.78 kJ/mol.The pre-exponential factor A was 4.567×108 min-1 and the values of n and m were 1.082 and 0.456,respectively.Based on the curing kinetic equation obtained,the calculated curing time of the system with 98% conversion rate was 115 minutes at the curing temperature 137.05 ℃.
