Abstract: In this paper, the cure kinetic parameters of the toughed epoxy resin (BA9913) were gained by dynamic DSC analysis based on the phenomenological model. Also, the phenomenological model of BA9913 resin was established. The curing degree of BA9913 were determined under different heating time at 100 ℃. Then, the relationship between curing degree and heating time of BA9913 resin was investigated with Dibenedetto equation based on the tested data, and the equation of glass transition temperature and curing time were obtained. The relationship between conversion at gelation and glass transition temperature of BA9913 resin was also obtained by shear modulus testing method. Then, the time-temperature-transition (TTT) diagram was presented based on the above results. Two kinds of T300/BA9913 composites under different isothermal time were manufactured by the guide of the TTT diagram. The internal quality, basic mechanical property and glass transition temperature of them were studied. The result show that the curing curve of T300/BA9913 now in use could be further optimized.

Key words: the toughed epoxy resin, BA9913, cure kinetic, glass transition temperature, time-temperature-transition diagram
