“…The restrained force on the yarns dramatically rises until some yarns are broken. 13,14 In our case, pristine material underwent typical puncture mechanisms, such as yarn pull-out and fabric windowing, leading not always to significant yarns fractures but merely to their separation, which allowed penetrator passage. 15 After the test, the fabric appeared to be pierced with slightly spilled fibers, but without evident signs of broken yarns.…”

In an attempt to improve the puncturing behavior of a commercial technical textile, this study investigated the effects of fabric impregnation with waterborne polyurethane dispersions (WPUDs). The infusing solutions were prepared by mixing a commercially available WPUD with other components, such as water, hydrophilic and hydrophobic silica (SiO2) nanoparticles, and a crosslinker. Quasi-static perforation tests were performed on a dynamometer machine equipped with a spherical spike and pointed blade as piercing probes. The results showed that the polyurethane impregnation augmented the puncture performances of the treated textiles. Then, further improvements in the spike and blade strength of the impregnated fabrics were obtained by adding hydrophilic silica nanoparticles and crosslinker into WPUDs, respectively. No effect of silica functionalization (hydrophilic or hydrophobic) has been verified on the mechanical features of the respective treated samples for the tested filler contents of 3% and 5% in wt. The best fabric features (blade strength increase of +63% and puncture strength increase of +71% compared to the neat material) were obtained by combining the two additives, nano SiO2 and crosslinker, into the polyurethane. The performances of these last systems were also superior to those obtained by doubling the amount of polymeric dispersion applied to the neat materials. The discussion of the results was supported by electron scanning microscopy, infrared spectroscopy, and further measurements of the cutting resistance. Finally, the mass per unit area of the substrate for the impregnated samples was measured in order to assess weight gain due to treatment.

“…However, the resistance to needle puncture is much more complex, and requires careful consideration of the tightness of the fabric and the sharp profile of the needle. The puncture behavior of woven fabrics was investigated by Sun et al 93 It was observed that in the initial stage, when a sharp object contacts a woven fabric, the warp and weft crimped yarns gradually straighten and are held under tension. The stress developed in the straightened yarns is transferred to the neighboring yarns due to the integrity of the woven structure.…”

“…Recently, several studies have been done to evaluate and improve the stab and puncture resistance of woven fabrics used for ballistic protection. 63,84,89,99,100 For example, the puncture behavior of woven fabrics was investigated from experimental and finite elemental analysis approaches by Sun et al 93 Three types (plain, 2/2 twill, and 2/1 twill) were tested under quasi-static conditions, and the load-displacement curves were plotted. Good agreement between the simulated and experimental results was obtained.…”

Since the invention of small arms ammunition, the human torso has required protection from hand-gun bullets, and today’s civil and military personnel are regularly clad in soft body armor systems to cope with these threats. However, increasingly, the threat spectrum has widened to include a plethora of both edged and pointed weapons. Over the past two decades in particular, this has required development of either specific soft armors to defeat that particular threat, or the development of multi-threat vests that can resist both hand-gun bullets and knife and spike attacks. In this review, we provide more details about the various material combinations that are used to defeat a knife or spike, since these armor materials are a lot different from the conventional aramid fabrics, and numerous, widely-different solutions are being pursued. The penetration mechanisms associated with the various forms of attack—stabbing and slashing—are discussed, as well as the use of new fibers, shear thickening fluids, and nano-materials in developing these body armor systems.

“…In addition, many researchers [3][4][5][6][7][8][9][10][11] relate their studies with the effect of friction by using various methods such as quasi-static test, puncture resistance test, yarn pull-out test, and through modeling (LS-DYNA). A recent study by Sun et al [12] reported the puncture behavior of woven fabric in plain, 2/2 twill, and 2/1 twill using finite element analysis (FEA).…”

A study was conducted on the puncture resistance of high-strength nonwoven natural rubber latex (NRL)-coated fabrics. High strength unidirectional (UD) polyethylene fabrics were coated using single dipping (SD), double dipping (DD), and triple dipping (TD) methods. The puncture resistance of the uncoated and coated fabrics was determined by measuring the force needed to penetrate the fabrics using a blunt probe. The mechanisms and modes of deformation involved during penetration were observed as well. In comparison with the uncoated fabrics, the SD, DD, and TD NRL coated fabrics gave higher puncture resistance of 39%, 47%, and 62%, respectively. The increments of the penetration force were proportional with the increase in the NRL-coated fabric thickness. For the uncoated fabric, the force given by the probe resulted in yarns stretching and yarn slippage upon penetration. However, the NRL-coated fabrics were not severely damaged but resulted in a curvature formed at the frontface of the fabric with minimal backface deformation. From the observations, the modes of failure were similar among the NRL-coated fabrics, that is, fiber stretching, delamination of NRL layer, and stretch marks on the fabric surface. The NRL layer acted as a protective sheath and increases the energy absorption and elasticity characteristics of the UD fabric.
