- Title
Sorption and diffusion of moisture in polymer composite materials with drop-weight impact damage.

- Abstract
The effect of drop-weight impact energy on the moisture diffusion coefficient and the limiting moisture saturation of next-generation GFRPs and CFRPs was investigated. The damage induced by a drop-weight impact decreased the compression strength and increased the moisture diffusion coefficient and the limiting moisture saturation of five tested polymer composite materials by 20-70% on the average. For describing the moisture uptake kinetics, the Langmuir model is found to be preferable, because the model with bonded and free water provided a coefficient of determination R ≥ 0.998.
