摘要: Abstract We investigated the effect of rigid spherical inclusions such as microcapsules and fillers on permeability fabrics by using glass beads model inclusions. Beads with a range diameters (40–800 μm) volume fractions (2.5–10%) were sieved between layers woven E-glass fabric targeting fiber fraction 40%. Permeability measurements completed X-ray microtomography to analyze samples pore structure estimate their Computational Fluid Dynamics simulations. Experimental numerical estimates also fitted Kozeny accounting for porosity specific surface samples. identified threshold curve related bead diameter below which follows that plain packed textile, above strong departure from this trend is observed, induced distortions textile. This behavior was closely correlated internal features
