Saturated transverse permeability of unidirectional rovings for pultrusion: The effect of microstructural evolution through compaction

The transverse permeability of roving/tow-based fiber reinforcement is of great importance for accurate flow modeling in the pultrusion process. This study proposes an experimental approach to characterize the roving-based fiber beds' permeability under different compaction conditions. The experimental permeability results of thick roving...
