A Comparative Analytical, Numerical and Experimental Analysis of the Microscopic Permeability of Fiber Bundles in Composite Materials

International audienceIn this comparative study, convenient analytical models evaluating the permeability of unidirectional fibrous media towards normal and parallel flow are selected. These models are compared with respect to available data early published. Static and transient mode simulations are launched in order to filter out the consistent bibliography values; analytical models are later compared with respect to the selected data.The analysis of the comparative study presents that Bahrami and Tamayol, Drummond and Tahir, Berdichevsky and Cai ISCM, and unified (square) models have good agreement with these data for longitudinal microscopic permeability components. Concerning transverse microscopic permeability, Berdichevsky and Cai ISCM (hexagonal), Gebart (hexagonal), Drummond and Tahir (hexagonal), and Kuwabara models are elected to be the most accurate models
