“…. The 3D orthogonal woven composite (3DOW) is distinguished by its intricate design, where three sets of yarns are integrated in three orthogonal directions [9][10][11][12][13]. In this architecture, the x-yarns (weft) and y-yarns (warp) remain straight without any crimp, while the binder (z-yarn) travels from the fabric's top to its bottom, oriented in the throughthickness direction.…”

This study investigates the effects of the number of layers, x-yarn (weft) density, and z-yarn (binder) path on the mechanical behavior of E-glass 3D orthogonal woven (3DOW) composites during low-velocity impacts. Meso-level finite element (FE) models were developed and validated for 3DOW composites with different yarn densities and z-yarn paths, providing analyses of stress distribution within reinforcement fibers and matrix, energy absorption, and failure time. Our findings revealed that lower x-yarn densities led to accumulations of stress concentrations. Furthermore, changing the z-yarn path, such as transitioning from plain weaves to twill or basket weaves had a noticeable impact on stress distributions. The research highlights the significance of designing more resilient 3DOW composites for impact applications by choosing appropriate parameters in weaving composite designs.

“…Compared with the traditional laminates, threedimensional (3D) woven C/SiC composites have the advantages of stronger design space, higher interlayer fracture toughness, and higher impact damage tolerance, receiving the attentions in aerospace and automotive industries. [1][2][3][4][5][6] In particular, the hybrid 3D woven C/SiC composites not only have the advantages of good integrity for the orthogonal woven structures but also avoid the poor interlayer performances due to the different properties of various fibers. In addition, the hybrid carbon fiber can greatly improve the elastic modulus and strength of composites.…”

Due to the effects of manufacturing process, there are lots of distributed voids in the interior area of three‐dimensional (3D) woven C/SiC composites, leading to the difficulties in predictions of damage evolution and ultimate strength. In this work, the mesoscale geometry of 3D woven C/SiC composites is reconstructed based on the high‐resolution CT scanning, considering the yarn path, yarn profile, and void content. The CT‐based reconstructed model agrees well with the experimental observations. Then, the constitutive laws of mesoscale constituents and macroscale structure are established and implemented numerically by the user‐defined material subroutine UMAT. Finally, the established constitutive laws are applied for the reconstructed model, and the mesoscale and macroscale nonlinear progressive damage behavior of 3D woven C/SiC composite structures are predicted using the hierarchical multiscale method, which are also validated by the experiments. The established CT‐based multiscale computational scheme would be a potential tool for performance evaluation and design of composites.

This study investigated the high‐velocity impact behavior of composite plates with different hybrid ratios and structural configurations through experimental and numerical simulation studies. The results showed that the critical penetration velocity of the composite plate generally increases with an increase in the volume fraction of aramid fibers. The high‐velocity impact finite element model developed in this study accurately simulated the high‐velocity impact behavior of laminated fiber composite plates with various hybrid ratios and different structures. The impact failure patterns of the plates were analyzed, and it was observed that the carbon fibers on the back face were prone to tensile fracture, followed by the gradual fracture of aramid fibers. The numerical simulation results show significant differences in residual impact velocity and energy absorption when impacted from different sides and the impact from the aramid side resulted in better energy absorption, which is contrary to the findings in many existing research papers. These findings provide valuable insights into the impact resistance of composite materials and can guide the design and development of high‐performance composite structures for aero‐engine case designing.Highlights The high‐velocity impact behavior of C/K fiber epoxy resin matrix composite laminates are studied. The critical penetration velocity increases with the increase of aramid fiber volume fraction. The laminate absorbs most of the impact energy during the instantaneous impact time. Energy absorption ability is better when the impact surface is aramid fibers. Carbon fibers on the back side of the laminate are more prone to tensile fracture.
