Abstract
The permeation and diffusion processes in continuously reinforced polymers were investigated from both theoretical and experimental viewpoints. Composite sheets were made by reinforcing cellulose acetate with glass ribbons. These sheets exhibited good adhesion between the filler and the continuous polymer phase. The permeability in the composite films was less than in the unfilled cellulose acetate due to increased tortuosity and increased polymer phase resistance to diffusion. To explain the experimental data, a mathematical model was developed using a modified equation originally formulated by Nielsen for composite permeability. Good agreement between the model predictions and the experimental data was achieved.Keywords
