In order to study the effect of crepe paper on the curing characteristics of epoxy resin, we analyzed the curing process of epoxy resin and epoxy impregnated paper system by differential scanning calorimetry (DSC). The kinetic model parameters of curing reaction were calculated by Flynn-Wall-Ozawa and Malek methods. The results show that both the curing reaction of epoxy resin and epoxy impregnated paper system conform to the autocatalytic kinetic model. The hydroxyl group in the crepe paper has a catalytic effect on the curing reaction, which leads to the decrease of the activation energy of the curing reaction. The restraint of crepe paper leads to the decrease of the frequency factor and reaction order, so that the curing rate of epoxy impregnated paper system is slower than that of epoxy resin. At the same temperature, the curing process of epoxy impregnated paper requires more time.
