Abstract

The selection of the optimal kinetic model of curing of a molten epoxy binder in a prepreg based on an equal-strength carbon fabric is considered step by step. The influence of the process stages and the reaction flow pattern on the coefficient of determination of experimental and calculated dependences is shown. Using the methods of multivariate nonlinear regression, two functional dependencies between factors and response were analyzed according to the Prout–Tompkins and Avrami–Erofeev models. The kinetic parameters of the curing reaction have been refined.
