In order to explore the process of using the new toughness curing agent， the curing kinetics of tetraglycidyl—4，4''—diaminodiphenyl methane （AG-80）/ triglycidyl-p-aminophenol （AFG-90） and triamine terminated polyether curing agent （TAPE） were investigated by non-isothermal DSC method. Málek method and isoconversional method were conducted to study the kinetics model and curing reaction mechanism， and mechnical properties of two epoxy systems were also explored. The results show that the initial curing reaction temperature of two systems are nearly 50^oC with good reactivity. The curing reaction process of the systems suit the Sestak-Berggren kinetic ［SB（m，n）］ model. The strain at break of two systems is higher than 3.74%， which shows the two systems have good reactivity and toughness.
