Краткое описание

A method of identifying the equilibrium moisture concentration in a thin polymer resin surface layer of a polymer composite material (PCM) is proposed. The purpose of the method is to estimate and predict moisture absorption throughout the volume of a composite package. The method also allows structural changes inside the surface layer to be detected. Over time, changes appear in the volume of the PCM, causing degradation of the exploitation characteristics of PCM materials and structures based on them.

Ключевые слова: composite, structure, moisture absorption, prediction, aging
