“…It is remarkable that the cross-linking of the UHMWPE fabric with as low as 1 wt % 1 resulted in a statistically significant increase in V 50 ( p < 0.05), especially given that the UHMWPE fabric was placed behind 11 layers of aramid material. As described above, we attribute this increased performance to intra- and interyarn covalent cross-links that may increase the energy absorbed by intrayarn sliding and interyarn slippage − (Figure C). Indeed, this is reminiscent of the hydrogen-bonding network that exists within aramid polymers, and which is thought to be the basis of the outstanding ballistics performance for aramid fabrics.…”

“…This network would strengthen the overall structure at two levels: improving the integrity of the yarns (intrayarn cross-link) and preventing slippage between crossing yarns (interyarn cross-links at intersections). This is particularly relevant when considering that interyarn friction and intrayarn sliding are major contributors to energy absorption during projectile penetration. − …”

We demonstrate that topical cross-linking of woven ultra-high molecular weight polyethylene (UHMWPE) fabric with a small-molecule bis-diazirine reagent can enhance the fabric’s resistance to tear and perforation and could provide a lead to further increase the protection provided by a soft body armor made from UHMWPE materials. A series of experiments confirms that the enhancement is likely due to cross-links formed within and between the yarns constituting the woven fabric and that cross-linking particularly strengthens the fabric along its bias direction. The treated fabric was incorporated into multilayer composite panels and challenged in ballistic tests. These measurements revealed that as low as a 1 wt % cross-linker can significantly increase the V 50 ballistic limit by 18 m/s.

“…The meso-scale yarn level FE models can help to analyze the stress propagation mechanisms in yarns more accurately. Chu et al [14] and Zhou et al [15] found in their simulations that the friction between yarn and yarn, yarn and projectile in plain woven fabrics is an important form of energy absorption. The energy absorption of the fabrics can be increased by controlling the inter-yarn friction in a certain range.…”

“…The penetration of projectile into fabrics is a complex nonlinear transient process, which is difficult to examine by experimental methods. The ballistic responses and impact energy absorption mechanisms of the fabrics can be further studied with the help of finite element (FE) modeling [12][13][14][15][16][17][18][19]. In the cases of fabric modeling, the macro-scale models often neglect the yarn geometry by homogenize the fabric structure, and the micro-scale models include too much details by modeling the filaments reactions within the yarns.…”

In order to achieve an efficient ballistic protection at a low weight, it is necessary to deeply explore the energy absorption mechanisms of ballistic fabric structures. In this paper, finite element (FE) yarn-level models of the designed three-dimensional (3D) angle-interlock (AI) woven fabrics and the laminated two-dimensional (2D) plain fabrics are established. The ballistic impact responses of fabric panels with and without the interlocking Z-warp yarns during the projectile penetration are evaluated in terms of their energy absorption, deformation, and stress distribution. The Z-warps in the 3D fabrics bind different layers of wefts together and provide the panel with structural support along through-the-thickness direction. The results show that the specific energy absorption (SEA) of 3D fabrics is up to 88.1% higher than that of the 2D fabrics. The 3D fabrics has a wider range of in-plane stress dispersion, which demonstrates its structural advantages in dispersing impact stress and getting more secondary yarns involved in energy absorption. However, there is a serious local stress concentration in 2D plain woven fabrics near the impact location. The absence of Z-warps between the layers of 2D laminated fabrics leads to a premature layer by layer failure. The findings are indicative for the future design of ballistic amors.

“…In the past decades, Shear Thickening Fluids (STFs) have been widely used in ballistic and impact-resistant materials and have attracted considerable research interest. 25 Therefore, in this study the low-velocity impact compressive response of the 3 D E-Glass Fiber Reinforced Polymer (GFRP) composites with the STF matrix as cushioning materials has been carefully investigated.…”

Whereas most previous studies have focused on improving the penetration resistance of Shear Thickening Fluids (STFs) treated composites, in this study, the dynamic compressive response of single and multi-ply 3 D E-Glass Fiber Reinforced Polymer (GFRP) composites with the STF matrix was investigated by using a drop-weight low-velocity impact test. The experimental results revealed the STF improved the compressive and cushioning performance of the composites such that with increasing its concentration, further improvement was observed. The five-ply composite containing the STF of 30 wt% silica nanoparticles and 1 wt% carbon nanotubes (CNTs) reduced the applied peak force by 56% and 26% compared to a steel plate and five-ply neat samples, respectively. A series of repeated impacts was performed, and it was found that the performance of high-concentration composites is further decreased under this type of loading.
