Abstract

A series of experiments on impregnation of viscous liquid to single-layer woven glass fiber mat are conducted. We mainly focus on the effect of the wettability between the viscous liquid and fiber bundles. It is found that impregnation velocity changes by varying the wettability. We illustrate how the macrovoids form by tracking the flow front in the fiber bundles under various capillary number. We indicate macrovoid formation is drastically affected by the wettability.
