“…The crack-arresting mechanism of such composites is improved by the uniform distribution and high surface area-to-volume ratio of the reinforcement (wire mesh) (Kaish et al, 2018). The wire mesh deformation and failure absorbed more than 80% of the impactor's kinetic energy, while frictional energy dissipation only accounted for roughly 10% of impact energy (Wang et al, 2021).…”

The current study use varied steel wire meshes in lightweight concrete to investigate the effects on mechanical properties in lightweight aggregate concrete (LWAC). There were three types of steel wire mesh used: hexagonal (chicken) wire mesh, welded square wire mesh, and expanded metal mesh in various layers and orientations in LWAC. Several mechanical properties such as flexural strength (FS), compressive strength (CS), and energy absorption (EA) were investigated. A total of 45 prisms specimens with dimension of 100x100x500mm ( width x depth x length) was casted for FS, 33 cube specimens were prepared for CS 150x150x150mm, whereas 45 specimens were costed for EA tests with a dimension of 400x300x75mm (LxWxH) respectively for 14 days of curing. The experimental results shows that the wire mesh as an additional reinforcement in the beam, enhanced the flexural behavior of the beam by distributing the forces along the section. The increment of the flexural resistance of the reinforced concrete due to the addition of one layer of chicken wire mesh, welded square wire mesh, and expanded metal mesh is 52.96%, 23.76%, and 22.2% respectively. The flexural strength in one-layer hexagonal wire mesh shows the highest FS which is 29.49MPa compared to the rest of the layers. However, the lowest FS were found in the wire mesh with one layer in all three meshes (hexagonal, welded, and expanded). There is a gradual decrease in the CS of concrete incorporating LWAC by increasing the layers of the hexagonal, welded, and expended wire mesh. The highest CS were found in the hexagonal wire mesh with one layer that is 36.56MPa. There is no such variation in the CS of combination of all three types of meshes and were found 29.79MPa. The highest energy was recorded in the expanded and chicken wire mesh with three layers before the ultimate failure that 1108.7 and 1425.6 Joul whereas, for welded square wire mesh, the highest energy absorption (752.3Joul) were found in the combination of three layer. For the first layer of hexagonal wire mesh reinforced concrete, the energy absorption was increased by 82.81% before crack whereas, it increases 88.34% before ultimate failure. Finally, it was concluded and recommended that hexagonal wire mesh outperforms than welded and expanded wire meshes.

“…Yang, 55 Wang, 56 and Wales 57 et al studied the failure mode of aramid mesh under medium-speed impact and stainless steel mesh under low-velocity impact successively. Yang placed the mesh with the most minor yarn diameter at the impact center; and used mesh with decreasing density at the fabric boundary.…”

Mesh-fabrics that enable flexible designability and structural mechanical load-bearing have been developing rapidly in the past several decades. Currently, there is an increasing demand for mesh-fabrics with lightweight and high strength in engineering fields. Nevertheless in practice, design, manufacture, and application of mesh-fabrics are often dealt with separately, which could lead to the performances of final products unable to meet the need of specific scenes. This article introduced the classifications and preparation processes of mesh-fabrics. The mechanical properties under various load conditions were described. Then different methods of structural and numerical simulations were reviewed. Current application status of mesh-fabrics were summarized; Finally, several suggestions have been provided to address challenges for the research, development, and application of mesh-fabrics. Look forward to the future, it is expected that mesh-fabrics will play a key role in innovative and high technology engineering fields.

“…[22] Otherwise, ion implanted glass has smaller bond angle, higher density and compressive stress, thus strengthening the surface of the material. [23,24] The mechanical properties of materials have an important influence on the LIDT of fused silica. Our previous researches indicated that argon ion implantation can lead to the reduction of Si-O-Si bond angle, the increase of surface density, the formation of compressive stress and the improvement of the mechanical properties and laser damage resistance of fused silica components.…”

Oxygen ions (O+) were implanted into fused silica at a fixed fluence of 1 × 1017 ions/cm2 with different ion energies ranging from 10 keV to 60 keV. The surface roughness, optical properties, mechanical properties and laser damage performance of fused silica were investigated to understand the effect of oxygen ion implantation on laser damage resistance of fused silica. The ion implantation accompanied with sputtering effect can passivate the sub-/surface defects to reduce the surface roughness and improve the surface quality slightly. The implanted oxygen ions can combine with the structural defects (ODCs and E' centers) to reduce the defect densities and compensate the loss of oxygen in fused silica surface under laser irradiation. Furthermore, oxygen ion implantation can reduce the Si-O-Si bond angle and densify the surface structure, thus introducing compressive stress in the surface to strengthen the surface of fused silica. Therefore, the laser induced damage threshold of fused silica increases and the damage growth coefficient decreases when ion energy up to 30 keV. However, at higher ion energy, the sputtering effect is weakened and implantation becomes dominant, which leads to the surface roughness increases slightly. In addition, excessive energy aggravates the breaking of Si-O bonds. At the same time, the density of structural defects increases and the compressive stress decreases. These will degrade the laser laser-damage resistance of fused silica. The results indicate that oxygen ion implantation with appropriate ion energy is helpful to improve the damage resistance capability of fused silica components.
