The possibility of using the dielectric analysis method to control the process of impregnation and curing of epoxy binders in the process of manufacturing products from composite materials is investigated. Ion viscosity was used as a control parameter for the impregnation and curing processes. It was shown that the data obtained by dielectric analysis reflect well the dynamic viscosity and cure kinetics of the thermosetting binder and are consistent with the rheology and differential scanning calorimetry data. The control curing scheme of the binder was simulated during the manufacturing process of the bracket auxiliary power unit of the helicopter. The results of this work can be used in the manufacture of products of complex shape from polymer composite materials.
