To understand the curing behavior of a new kind of high temperature curing carbon ifber rein-forced epoxy prepreg in depth, differential scanning calo-rimetry (DSC) is carried out to make a systematic research on the characteristic parameter and cure degree of the cur-ing action, and the cure kinetic equation is obtained by ap-plying a phenomenological model. Through the research, the apparent characteristic curing temperature of the resin system is acquired, which provides theoretical foundation and basic data for determination and optimization of the curing process of the prepreg.
