“…The kink band formation may come from fiber bending because of the roller imprint in the three points bending loading. 32,33 For Specimen B, significant matrix cracks and delamination are found at the bottom as shown in Figure 9(b). Meanwhile, AE signals with high-amplitude and high-energy are generated, as shown in Figures 5(b) and 6(b).…”

Two kinds of carbon aramid/epoxy hybrid woven composite specimens with different fiber orientations were prepared. The progressive flexural damage behaviors of the composites were studied. The failure process was monitored in real time by acoustic emission during the test, and the characteristics of the acoustic emission signals originating from the damage were deeply studied. In addition, the internal damage initiation/evolution and failure mechanisms were characterized by X-ray micro-computed tomography. The results show that composite specimens exhibit higher strength and obvious quasi-brittle damage behavior when carbon fiber orients along the loading direction, and the macroscopic failure is mainly shear fracture, which propagates in the direction of thickness, and the damage is dominantly distributed above the neutral plane of specimen. When aramid fiber orients along the loading direction, composite specimens show high ductility and the failure modes are mainly ply fracture at the bottom, delamination (inter-ply delamination and intra-ply delamination) and tensile fracture of the tows. The combination of acoustic emission and X-ray micro-computed tomography analysis provides an insight for further elucidation of the progressive damage initiation/evolution and failure mechanism of composites.

In recent years, the research interest on three-dimensional warp interlock woven fabrics (3DWIFs) as reinforcement in composites is warranted and obtained popularity due to their advantages over two-dimensional laminated fabrics. The current literature tends to address the aspects of mechanical properties of 3DWIFs by experimental and numerical approaches. This review aims at providing an overview and comprehensive understanding of dry 3DWIFs. The filaments/yarns used, the common structures, and categories of 3DWIFs are reviewed. Recent characterizations of the mechanical performance of dry 3DWIFs are discussed. Theoretical and numerical models for predicting the mechanical properties of dry 3DWIFs are also delineated. The critical review can provide valuable ideas and guidance for future studies.

“…Due to their lower crimps, the warp and weft interlock composites showed better tensile behavior as compared to the bi-directional interlock composite. The off-axis angles among the different yarns while developing the 3D woven fabrics also showed an influence on the mechanical properties of the materials [ 35 , 36 ].…”

Recently, three-dimensional (3D) warp interlock fabric has been involved in composite reinforcement and soft ballistic material due to its great moldability, improved impact energy-absorbing capacity, and good intra-ply resistance to delamination behaviors. However, understanding the effects of different parameters of the fabric on its mechanical behavior is necessary before the final application. The fabric architecture and its internal yarn composition are among the common influencing parameters. The current research aims to explore the effects of the warp yarn interchange ratio in the 3D warp interlock para-aramid architecture on its mechanical behavior. Thus, four 3D warp interlock variants with different warp (binding and stuffer) yarn ratios but similar architecture and structural characteristics were engineered and manufactured. Tensile and flexural rigidity mechanical tests were carried out at macro- and meso-scale according to standard EN ISO 13 934-1 and nonwoven bending length (WSP 90.5(05)), respectively. Based on the results, the warp yarn interchange ratio in the structure revealed strong influences on the tensile properties of the fabric at both the yarn and final fabric stages. Moreover, the bending stiffness of the different structures showed significant variation in both the warp and weft directions. Thus, the interchange rations of stuffer and binding warp yarn inside the 3D warp interlock fabric were found to be very key in optimizing the mechanical performance of the fabric for final applications.
