“…The non-spherical deformation was caused by the orientation of the textile fibers, which can also be seen in Figure 12c, where the deformation of the fiber bundles is very clear. The theoretical and experimental approach of woven fiber in the carbon composite at various axis of damage during dynamic loading was described in literature [28] and well matches with the damage behavior observed here, such as matrix cracking and fiber debonding on the composite. The overall fiber orientation and rupture through the composite from the edge towards the center is supported by the supplementary file Video S1.…”

The internal structure of fiber reinforced geopolymer composite was investigated by microfocus X-ray computed tomography (µCT) under mechanical impact. µCT is a non-destructive, multi approach technique for assessing the internal structures of the impacted composites without compromising their integrity. The three dimensional (3D) representation was used to assess the impact damage of geopolymer composites reinforced with carbon, E-glass, and basalt fibers. The 3D representations of the damaged area with the visualization of the fiber rupture slices are presented in this article. The fiber pulls out, and rupture and matrix damage, which could clearly be observed, was studied on the impacted composites by examining slices of the damaged area from the center of the damage towards the edge of the composite. Quantitative analysis of the damaged area revealed that carbon fabric reinforced composites were much less affected by the impact than the E-glass and basalt reinforced composites. The penetration was clearly observed for the basalt based composites, confirming µCT as a useful technique for examining the different failure mechanisms for geopolymer composites. The durability of the carbon fiber reinforced composite showed better residual strength in comparison with the E-glass fiber one.

“…For traditional meso-scale finite element solid models, the discrete mesh are quite tedious owing to the complex yarn architecture and the cross section shapes. A non-uniform element size and distorted elements are most probably obtained, which not only affects significantly the computational efficiency of the analysis, but also results in the inaccurate stress and strain distribution [17,18]. Voxel meshing is an advanced method to generate meshes of any kind of textile architecture.…”

A study is conducted with the aim of developing voxel-based finite element method related to the whole fiber distribution for predicting the macro-mechanical properties of 3D orthogonal woven composites. For the rationality of this model, multi-scale finite element method, which is on the basis of the surface and interior representative volume cells, and digital image correlation tests are carried out. The results show that the proposed voxel-based finite element method is capable of precisely calculating the macro-level properties of 3D orthogonal woven composites, validated by the comparison the mechanical behaviors as well as the full-field strain fields.

“…They conducted parametric studies to ascertain how the fiber strength distribution affects material mechanical properties. Patel et al 19,20 conducted tensile and compression experiments and dual-scale modeling research on hybrid 3D woven composites. They utilized a dual-scale model to replicate the evolution of damage during tension and compression, analyzing the effects of fiberbundle bending and geometric defects.…”

Three‐dimensional (3D) orthogonal woven composites can overcome the drawback of weak interlaminar strengths in traditional laminated composites and exhibit excellent resistance to out‐of‐plane impact, however, the significant difference in properties in the in‐plane orthogonal direction will limit the potential range of application thereof. Predicting elastic properties and exploring methods of adjustment are therefore of paramount importance. Using computed tomography (CT) scanning to obtain detailed parameter models, a corresponding dual‐scale model of microscopic representative volume element (RVE) and mesoscopic RVE was established, and the accuracy of the model was experimentally validated, which can predict the elastic properties of materials. In addition, the influences of the yarn fiber volume fraction and weaving distance on elastic properties were evaluated using the elastic modulus visualization method, and a formula integrating these two factors is provided for adjustment of the in‐plane orthogonal Young's modulus.Highlights Experimentally validated microscale and mesoscale RVE models were established. The influences of factors on elastic properties were visualized. The relationship between Young's modulus and influencing factors was derived. A reliable strategy for adjusting the in‐plane Young's modulus was proposed.
