Saturated transverse permeability of unidirectional rovings for pultrusion: The effect of microstructural evolution through compaction
Abstract
<jats:title>Abstract</jats:title><jats:sec><jats:label /><jats:p>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‐based preforms were reported and compared with the permeability values of roving‐based preforms in the literature. A representative preform was infused under vacuum conditions. Its thickness was varied to replicate the different compaction values observed in permeability tests. Micrographs were then collected from it and analyzed to highlight the microscale transformations caused by processing/compaction on the fiber arrangement. The analysis revealed that compaction resulted in the reorganization of filaments along the direction of the applied compaction. Overall, the uniformity of the spatial filament distribution, i.e., the homogeneity within the fibrous domain, increased with increasing compaction. Furthermore, the microstructural analysis demonstrated transverse anisotropy within the tested domains, indicating that the obtained permeability results represented an upper boundary. In addition to the experimental analyses, various transverse permeability models, which were developed based on recently introduced statistical descriptors of fiber distribution, were evaluated by using the statistical descriptors extracted from the analyzed cross‐sections. Among these models, the one correlating the second neighbor fiber distance with apparent permeability exhibited good agreement with the experimental results.</jats:p></jats:sec><jats:sec><jats:title>Highlights</jats:title><jats:p><jats:list list-type="bullet"> <jats:list-item><jats:p>Transverse permeability measurement of a roving‐based reinforcement was presented.</jats:p></jats:list-item> <jats:list-item><jats:p>The influence of compaction on the microstructure was investigated at the filament level.</jats:p></jats:list-item> <jats:list-item><jats:p>Filament distribution in a pultruded profile was analyzed by using statistical descriptors.</jats:p></jats:list-item> <jats:list-item><jats:p>The results of the experiments and the models in the literature were compared.</jats:p></jats:list-item> <jats:list-item><jats:p>The correlation between microstructural features and apparent permeability was discussed.</jats:p></jats:list-item> </jats:list></jats:p></jats:sec>
