Abstract
The methods of differential thermal analysis (DTA) and differential scanning calorimetry (DSC) have been used to study the kinetics of curing a thermoset epoxy binder, complicated by intensive self-heating, in an adhesive prepreg based on aramid Ruslan fiber. The most adequate reaction scheme has been chosen and the kinetic parameters of the curing reaction have been determined for each elementary stage. A generalized kinetic model of the reaction has been constructed based on experimental data obtained by DTA and DSC. The selected model has been tested by solving an opposite problem—namely, constructing a series of calculated DTA and DSC curves and evaluating their compliance with the experimental data.
