Selection of Fitting Models of the Moisture Content for Paper Honeycomb Sandwich Panel

The influence of temperature and relative humidity on the moisture content of paper honeycomb sandwich panels was studied. The moisture content of paper honeycomb sandwich panels was fitted by three mathematical models. The fitting results were evaluated by experimental data, and the best fitting model and its parameters were determined. The results indicate that in three models, the GAB (Guggenheim, Anderson and De Boer) model is the best suited to predict the moisture content of paper honeycomb sandwich panels in different temperature and humidity conditions.
