Abstract:
The work is focused on mechanical and ballistic properties of textile materials most used in personal protection (ballistic vests, helmets), i.e. aramid fabrics. Physical and mechanical properties such as Young’s modulus, maximum strength before rupture, tensile strength, elongation at rupture and combustion velocity were measured. Ballistic resistance of sets of selected fabrics was tested. Ballistic tests were focused on protection level TBO-2/CZ according to ČSN 395360.

Abstract:
Multiple layers of ballistic fabrics are extensively used in the production of soft body armour. The importance of comfort and hence its evaluation for these fabrics is gaining significance among present day researchers. This research compares 100% Kevlar ballistic fabric and Kevlar/wool ballistic fabric focussing on two aspects of comfort, namely the evaluation of surface roughness and the ability to transport moisture. A water repellent treatment was applied to the ballistic Kevlar/wool fabric. The effects of the treatment on the Kevlar/wool fabric were examined as well.

Abstract:
Experimental studies have shown that flexible woven fabrics can absorb significant kinetic energy from both projectile and fragment impacts through a combination of design factors which include yarn materials, weaving architectures, yarn density ratios, as well as the projectile mass, shape and velocity.1–3 This paper investigates the relationships between various plain-woven fabric architectures, crimp imbalance and energy absorption capacities when rigid projectile strike these fabrics through a series of analytical solutions. This was accomplished through formulations of the yarn pullout an

Abstract The paper presents the issue of a knife proof ballistic package. This issue was emphasized since most of modern vests are designed to match the threat posed to them only by firearms. There was observed negligence of protection against melee attacks. There is, thus, a need to develop a research methodology in this matter, because it is a valid and necessary problem in a modern developed society. The aim of this study was to perform a numerical model which simulated the phenomenon of penetration of a ballistic package by an engineering blade. Specification of an engineering blade was ta

Essential aspects of numerical analysis for bullet hitting elastic layers of aramid fabric placed on a plastic substratum imitating the human body are presented in the paper. A review of results for bullet-proof vests tested on various substrata is included in the paper with justification of their use. It is explained why the ballistic plasticine is used as a substructure imitating the human body in most standards binding in the world for testing individual protections. Methods for modelling the fabrics with results of own numerical analyses are presented. As mutual reaction of yarns creating

Abstract:
Even though natural fiber reinforced polymer composites (NFRPCs) have been widely used in automotive and building industries, there is still a room to promote them to high-level structural applications such as primary structural component specifically for bullet proof and ballistic applications. The promising performance of Kevlar fabrics and aramid had widely implemented in numerous ballistic and bullet proof applications including for bullet proof helmets, vest, and other armor parts provides an acceptable range of protection to soldiers. However, disposal of used Kevlar products would affec

Abstract:
Graphene oxide (GO) incorporation in natural fiber composites has recently defined a novel class of materials with enhanced properties for applications, including ballistic armors. In the present work, the performance of a 0.5 vol % GO-incorporated epoxy matrix composite reinforced with 30 vol % fabric made of ramie fibers was investigated by stand-alone ballistic tests against the threat of a 0.22 lead projectile. Composite characterization was also performed by Fourier-transform infrared spectroscopy, thermal analysis and X-ray diffraction. Ballistic tests disclosed an absorbed energy of 130

Abstract:
The ballistic resistance of high-strength fabrics improves upon impregnation with Shear Thickening Fluids (STFs). The performance of such STF treated fabrics depends on the rheological properties of the STF which in turn are governed by the physicochemical properties of the STF. The present study utilizes rheological characterization of shear thickening silica-polyethylene glycol dispersions (of different material configurations in terms of packing fraction, particle size and continuous phase viscosity) to assess their performance and obtain the best STF material configuration for ballistic bo

Abstract:
The tensile testing of a needle-punched nonwoven fabric is presented. A high-sensitivity Split-Hopkinson Tensile Bar device was specifically designed for this purpose. The strain gauge measurements were combined with high-speed photography and Digital Image Correlation to analyse the deformation micromechanisms at high strain rates. The experimental set-up allowed to determine the wave propagation velocity of the as-received nonwove fabric, the evolution of the strain field with deformation and the wave interaction inside the fabric. The deformation was accommodated by the same micromechanisms
