The aim of this work is to prepare an novel phenolic resin(PF)film suitable for RFI process and gen鄄 erate its TTT cure diagram. Dynamic DSC technique was conducted to establish curing kinetic model that was used to describe the relationship of curing degree time temperature and of curing degree鄄glass鄄transition temperature on isothermal conditions. Establishing the relationship between the glass鄄transition temperature and curing degree allowed the determination of the vitrification lines of the resol resins. In addition, a gelation disk experiment was employed to study the gelation of resol resins. The degree of cure at gelation was found around 53. 33%. Based on the above results timetemperature transition diagram was presented.
