Curing kinetics model

WebJan 18, 2024 · The isothermal kinetics of curing was described by means of model fitting and the isoconversional approach (Friedman method). Accurate n-order approximation was obtained for all systems under study. In particular, the 2-order equation fits well with the main part of curing excluding high degrees of conversion. WebCuring Kinetics Models. The resin material models in Inspire Resin Transfer Molding support two models for simulating curing kinetics, the Generalized Curing Kinetics Model and the Constant Rate Curing Kinetics Model. Both of these models are used to compute the "degree of curing", which is a scalar variable. Its value ranges from 0.0 to 1.0.
