“…In other words, puncture mechanisms such as yarn sliding and windowing are most directly modified by restricting the ability of fibers and yarns to reorganize and move relative to each other. In contrast, compression, shear and transverse failure are more directly related to the mechanical properties of the fabric filaments [3,12,33,34,[42][43][44]. Figure 13 depicts the comparison between maximum bearable load and maximum energy absorption by the untreated and 15, 25 and 35 wt% STFs-treated composites.…”

“…Owing to the low speed of the penetrator, as the QS load is applied to the untreated Twaron, the applied stress is transferred along the yarns to the fixed edges of the fabric [23,33,40]. However, because of a lack of sufficient friction between the fibers and penetrator, between fibers themselves and between the yarns at yarn crossover areas, the penetrator passes through the fabric by puncture mechanisms.…”

“…The influence of molecular weight of polymer medium [9,15,29] and silica nanoparticle size [10,12,30,31] on rheological and mechanical properties of the fabric-STF composite have already been discussed. The performance enhancement provided by the STF is suspected to be due to the increased frictional interaction between the yarns [3,12,[29][30][31][32][33]. The increased friction resulting from the presence of nanoparticles between the filaments and the shear thickening phenomena as well as the friction between the filaments and the penetrator lead to the higher occurrence of fiber breakage than the sliding of fibers under high-velocity impact loading [4,12,20,34].…”

Intelligent energy shunting fluid/fabric base structure which utilizes well-processed shear thickening fluid has been developed. The shear thickening fluid has been synthesized by a powerful mechanical stirrer to disperse 12 nm silica particles into polyethylene glycol 200 g/mol at three concentration levels from low to near maximum packing as 15, 25 and 35 wt%. Examining the rheological behavior of the shear thickening fluid indicates that the increase of shear thickening fluid concentration leads to significant increase in the suspension's initial, critical and ultimate (up to 10 4 Pa.s) viscosities, reduction of the critical shear rate, increase of viscoelastic modulus and instability of the suspension. The quasi-static puncture test results demonstrate with the increase of shear thickening fluid concentration, the maximum bearable load by the 15, 25 and 35 wt% shear thickening fluids-treated Twaron Õ composites increases by 132, 315 and 362%, and the energy absorption increases by 143, 159 and 209%, respectively, compared to the neat fabric. Regarding penetrator structure and dimension, by using rounded penetrators, windowing and pull-out mechanisms would be expected at low velocities. However, sharpnosed penetrators most likely cause yarns to push aside that is not taken into account Downloaded from as a perfect criteria for investigation of puncture resistance performance. Also, larger penetrators have a larger presented area of impact and, as a result, break more number of yarns to penetrate the fabric.

“…Failure of soft elastomer-coated fabric caused by an indenter or blade has not much been investigated. Some researchers have tested the puncture resistance of coated fabrics using a pointed blade [3], rounded probe [4,5] or flat-tipped cylindrical probe [6]. Specific puncture mechanisms such as fiber stretching, breaking, and delamination have been considered the main contributors to the puncture of an uncoated material by a rounded probe [7], but Hassim et al [4] showed that all these mechanisms become insignificant in the puncturing of coated fabrics, due to the effect of the coating layer.…”

Soft elastomer-coated fabrics are widely used in engineering and protective applications. Puncture cutting by sharp-tipped objects is one of the most common failure modes of protective gloves made of coated fabrics. In order to investigate the puncture-cutting process of soft elastomer-coated fabrics, we studied the mechanisms and mechanics of pointed-blade insertion into specimens cut out from four protective gloves. Experimental and analytical analyses showed that total energy and critical puncture-cutting force calculated analytically are both able to predict the puncture-cutting resistance of soft elastomer-coated fabrics measured experimentally. Total energy is obtained from the relationship between the puncture-cutting work and the created fracture area, while critical force is calculated by two analytical models developed for soft elastomeric membranes. The components of the critical puncture-cutting force are predicted analytically and then used to calculate the compressive and shear loading stress components based on the contact surface between the pointed blade tip and material. Since there is a linear relationship between the compressive stress component and shear stress component, a modified linear strength criterion is proposed for puncture cutting of soft elastomer-coated fabrics by a pointed blade. Our stress-based criterion connects the 45° tensile strength (in the 45° direction) and biaxial strengths (in the course direction, 0°, and wale direction, 90°) to both compressive and shear loading stresses. The analytical and experimental results are consistent. This investigation can be used as a guideline to evaluate the puncture cutting of soft elastomer-coated fabrics using an energy-based criterion, critical force-based criterion, or stress-based criterion.

Ultra‐high molecular weight polyethylene (UHMWPE) is commonly used with many layers to realize protection and this can greatly benefit from advancements in fabric mechanical properties. This research introduces an innovative approach to crafting a composite felt, leveraging UHMWPE fabric, carbon nanotubes (CNTs), shear thickening fluid (STF), and polyvinyl alcohol (PVA) binder through a spray technique. The method results in a fabric with exceptional tensile strength and anti‐impact characteristics. Observations during the fabrication process reveal profound surface morphology alterations, showcasing an intricate layering of PVA binder, CNTs, and STF that seamlessly encapsulates each component of the STF/CNTs/UHMWPE system. The tensile strength and anti‐impact properties including punch residual velocity and energy absorbed are 564.0 ± 12.4 MPa, 1.537 ± 0.032 m/s and 22.952 ± 1.158 J in 12 ms, increased by 143.3%, 24.3% and 193.3%, respectively, compared to neat UHMWPE. This substantial performance uplift is attributed to multiple factors: the reinforcing friction between fibers/yarns fostered by the PVA binder and the full or partial embedding of CNTs, the additional reinforcing strength imparted by the CNTs matrix, and the dynamic viscosity enhancement of STF under impact forces.Highlights Anti‐impact felt was prepared by spraying PVA, CNTs, and STF onto UHMWPE. The tensile strength of anti‐impact felt was improved by 143.3%. The energy absorbed and impact depth was raised by 193.3%. The enhanced friction between fibers is caused by PVA and CNTs. The strength of CNTs and increased viscosity of STF under impact are notable.
