“…Since the properties of the subcell were obtained by the equivalent homogenization of fiber bundles with matrix, the 0 and 90 subcells can be considered unidirectional fiber-reinforced composite for analysis. 44,45 An optimized 3D Hashin failure criterion was introduced by combining the theories of Hashin 46 and Hou, 47 comprising four failure modes (including longitudinal tension, longitudinal compression, transverse tension and transverse compression), which can be expressed as follows:…”

The jointing problem has become increasingly prominent with the growing applications of composites in industrial fields. Besides, the hybrid bonded‐bolted (HBB) joint has aroused extensive attention for its excellent mechanical performance. In this study, numerous tests and simulations were conducted to investigate the load‐bearing performance of the plain‐woven carbon fiber‐reinforced plastic (CFRP) laminates HBB joints under quasi‐static uniaxial tensile conditions. The influence of HBB morphological parameters was systematically analyzed. The 3D Hashin failure criterion was successfully implemented in the finite element model for the failure analysis of a numerical equivalent cross‐ply laminate structure.Highlights FEA‐based mechanical property analysis tool for CFRP bonded‐bolted joint. Quantitative influences of HBB morphological parameters are discussed. Failure modes of HBB with different characteristics are revealed.

“…There are various reasons for this, such as structural insufficiency, deficient concrete, great incoming loads and sometimes complying with the new standards (Aljazaeri Zena, 2018;Saeed et al, 2022b;Zeybek et al, 2022). Several strengthening composites and systems ranging from engineered cementitious composites (ECC), fibre reinforced polymers (FRP), textile reinforced mortar (TRM) and steel reinforced grout (SRG) have emerged for upgrading the civil engineering structures (Xie et al, 2022;Liu et al, 2023;Sadrolodabaee et al, 2023). Among these TRM gained great recognition as strengthening material for existing structures.…”

Textile reinforced mortar (TRM) is mainly used for strengthening of existing structural members whereas, on the other hand Textile reinforced concrete (TRC) is a technology implied in construction of new members for enhancing the structural behaviour. Application of TRM on the tension zone of the reinforced concrete (RC) slabs to improve the flexural capacity has been investigated by many researchers in the past. However, the effectiveness of textile fabrics, used as internal reinforcement in the RC slab (TRC technology) needs to be studied. The paper, therefore, presents the experimental research conducted on three one-way RC slabs specimens reinforced using textile grid. An innovative Polyacrylonitrile (PAN) based carbon textile grid was used as internal reinforcement in combination with the steel bars. Two textile-reinforced RC slabs having one and two layers of textile grid (SRC + 1T and SRC + 2T respectively) and one reference slab (SRC) was fabricated to investigate the flexural behaviour under a four-point loading system. The internal textile reinforcement layer(s) was confirmed to be effective, particularly in terms of improving the cracking load, ductility, deformability and toughness. The material ductility of SRC + 1T and SRC + 2T slabs were increased by 41% and 44% compared to SRC slab. Also, the deformability ratio was found to be greater than 4, indicating a ductile failure of textile-reinforced slabs. Further, based on the load-deflection relation, moment-curvature curves were derived. Moreover, these curves were also developed using Eurocode two prediction model. The experimental and the predicted moment-curvature curves showed good agreement.

“…Continuous-filament fabrics made of high-strength and high-stiffness fibers have high flexibility and lightweight advantages and are widely employed in the blast and ballistic protection systems (Wang et al., 2023). The fabric’s architecture significantly affects the fabric targets’ protective ability (Liu et al., 2023; Miqoi et al., 2020; Pan et al., 2021) and ballistic mechanisms (Abtew et al., 2019a). Many studies have been conducted on the impact resistance of high-performance fabrics.…”

3D angle interlock woven fabric(3DAWF) has great potential for impact protection. This paper investigates the ballistic mechanism of 3DAWF(5 layers of angle interlock – through the thickness) under normal and oblique impact. The full-size mesoscale model of 3DAWF under different impact directions and angles was established and systematically studied to reveal the 3DAWFs’ ballistic mechanism. The numerical studies of 3DAWF subjected to 0°, 15°, 30°, 45°, and 60° oblique impacts from two impact directions along 3DAWF structure configurations were carried out. We found that 3DAWFs’ ballistic performance increases non-linearly with impact obliquity. The ballistic mechanisms change with impact directions because of 3DAWFs’ anisotropic structure. This work also demonstrates the impact damage mechanism, energy absorption evolution, and stress wave distribution of the 3DAWF under oblique high-velocity impact. The findings are constructive for the 3DAWF applicated in ballistic protection.
