Time-temperature-transformation (TTT) cure diagram for EPY epoxy system

Abstract: Time-temperature-transformation (TTT) cure diagram for EPY ® epoxy system Summary-Curing reactions of the EPY ® epoxy system (Epidian 6 + TETA) applied for machine foundation chocks were studied to determine time-temperature-transformation (TTT) isothermal cure diagram for this system. Differential scanning calorimetry (DSC) and rotational viscometry were used to obtain the experimental data. Empirical models based on dependence between conversion degree and glass transition temperature, as well as reckoning o… Show more

“…De Benedetto's equation is one of the most widely used method for describing the variation between T g and curing degree. 2,26,27 An empirical parameter λ is used to correlate the T g of the incompletely cured sample to those of the uncured and totally cured samples, as shown in eq. (7):…”

“…In this work, the different cure states are achieved by choosing different curing temperatures, due to the fact that the maximum achievable degree of cure below the glass transition temperature is limited through the diffusion controlled termination of the reaction (see [7]). A widely used measurement technique is the torsional parallel plate rheometer (see [22,25,27] and further works).…”

“…A CTT cure diagram is based on the data similar to the data collected for the time-temperature-transformation (TTT) isothermal cure diagram introduced and developed by Gillham et al [7,8]. The TTT diagram calculated for the EPY ® epoxy system was presented in the previous article [9]. CTT diagram can be developed through a certain transformation of TTT diagram [9,10] bearing in mind that gelation occurs at the same chemical conversion regardless of temperature [5].…”

“…The TTT diagram calculated for the EPY ® epoxy system was presented in the previous article [9]. CTT diagram can be developed through a certain transformation of TTT diagram [9,10] bearing in mind that gelation occurs at the same chemical conversion regardless of temperature [5]. Therefore, a gelation curve in TTT diagram becomes transformed into a gelation line in CTT diagram, whereas the vitrification curve is now presented as the glass transition conversion-temperature curve (Fig.…”
