This study presents the results of investigating the effect of moisture on the dielectric properties of epoxy materials. Measurements were carried out using gravimetric and dielcometric methods with an LCR meter at 12 kHz. A strong correlation was established between changes in dielectric permittivity and moisture content, confirming the applicability of the method for quantitative in situ moisture monitoring. Additionally, FTIR spectroscopy revealed signs of hydrolytic modification and plasticization of the epoxy network. The dielcometric method demonstrated high sensitivity to structural variations and proved to be a promising tool for diagnosing critical polymer components under operating conditions.
