ABSTRACT
This is a statistical study of the dynamic humidity diffusion through the polyester/glass fibre composite. It analyses the influence of the environmental conditions like the temperature, the flow velocity and the pressure on the humidity diffusion through the composite material. It is divided into an experimental plan and a data analysis, which exploit the experimental results in order to analyse the process of humidity diffusion by highlighting the effects of the influencing parameters. The increase in the temperature, the pressure, the flow velocity and the percentage of fillers additives (ASP400) induce an augmentation in the diffusion coefficient and the amount of absorbed humidity. We can affirm that the flow velocity and the pressure have a higher impact on the diffusion parameters than the temperature. Moreover, the increase in the percentage of the fillers additives (ASP400) decreases the effect of the pressure and the flow velocity on the diffusion parameters.
