“…As indicated, the overall thickness of the specimen decreases by 0.64 mm from the lowest fiber volume content of 47.4% to the highest one of 54.4%. These geometric models are different from the ones reconstructed in other studies ( [45][46][47][48] ), because all the fiber tows of the fibrous reinforcement are identified and individually labeled. Thus, the geometric features, orientations, and mechanical properties of fiber tows can be taken into account in the analysis.…”

“…The structured voxel file created allows a thorough analysis of the geometric features of the fiber tows contained in the specimen. • Material variability: Lower resolution micro-CT scans enable to model larger specimens that are more representative of material variability than single unit cells like in most previous investigations ( [32,[44][45][46] ). • Numerical simulations: Because the structure of the material has been identified and all the tows numbered, it is possible to create finite element meshes of the fibers and/or of the mesopores between the tows.…”

“…Transverse compaction can further cause the sinking of Z-crown into the surface weft yarn [24,25] and the flattening and widening of the warp and weft yarns. Asymmetrical shapes of the binder yarn [26], crimping of the through-thickness segment of the binder yarn [27,28] and fiber-breakage during 3D weaving [29] can also arise.…”

“…Image-based approaches were adopted in [25,26] to generate realistic geometrical models of 3D woven composites. To this end, the images of micro-CT scans were transformed into a voxel-based mesh representation [26] or into a tetrahedral mesh representation [25].…”
