Abstract

The kinetics of curing binder in prepreg was studied by differential scanning calorimetry method. The most adequate scheme of the curing reaction was selected and the kinetic parameters of the curing reaction for each elementary stage of the process were determined. On the basis of experimental data, generalized kinetic models of the curing reaction were constructed, and then the curing modes of the binder in the prepreg were selected were selected based on both experimental and calculated data, which were tested on technological equipment. As a result, the degree of material curing was determined.
