Ballistic Performance of Kevlar49/ UHMW-PEHB26 Hybrid Layered-Composite

Abstract

This experimental study investigates the effects of plies number on ballistic performance of Kevlar49/ UHMW-PEHB26 (ultra high molecular weight polyethylene) layered-hybrid composite. Ballistic performance of the composite samples is explained in terms of trauma depth, energy absorption capacity and the mechanisms that lead to perforation in varied composite samples. Ballistic tests are performed according to NIJ 0101.04 Level-III standards. The results is showed that the produced composite samples excluding Type V-composite provide Level IIIA protection according to NIJ 0101.04 standard. The critical number of ply for Kevlar49/ UHMW-PEHB26 layered-hybrid composite is obtained as 16 plies consisting of 8 plies for each fabrics. Trauma depth increases with decreasing total number of plies in the composite samples. The energy absorption capability of the layered-composite decreases with decreasing total number of plies. Energy absorption mechanisms are explained by strain energy of the plies due to straining and fracture of yarns, delamination of plies and layers, and friction energy between plies, and the mobility of yarns.

Fibre-Reinforced Composite for Protection against Shark Bites

“…Ballistic protection has long incorporated Kevlar composites that reduce trauma depth and absorb vast quantities of energy associated with projectile impacts. It was determined by Yavaş et al [14] that trauma depth increases with a decreasing number of total layers in the composite samples tested. The energy absorption capability also decreases with a reduction in total number of layers.…”

Enhancing the Ballistic Performances of 3D Warp Interlock Fabric Through Internal Structure as New Material for Seamless Female Soft Body Armor Development

“…However, achieving proper female soft body armor not only needs a unique panel design technique but also appropriate material that is moldable, reasonably light in weight, and comfortable without compromising its ballistic performance toward projectile penetration [8]. In general, the ballistic performances of textile-based soft body armor influenced by various internal factors including fiber types, yarn properties, material areal density, target plies numbers, target ply sequence fabric construction, such as woven/nonwoven and 2D/3D fabrics [9][10][11][12][13]. Twaron ® , Kevlar ® , Dyneema ® , and Spectra ® are commonly used high-performance fibers to produce body armor systems due to their high resistance-to-impact damage [12,14,15], high strength, high tenacity, good chemical resistance and lightweight characteristics [16,17].…”

For the last many decades, 2D plain weave and UD fabric structure made from high-strength fibers have been used in personal body armor development due to their excellent mechanical properties and ballistic performances [18][19][20][21][22][23][24].…”

Ballistic impact performance and surface failure mechanisms of two-dimensional and three-dimensional woven p-aramid multi-layer fabrics for lightweight women ballistic vest applications

“…Among those fabrics, two-dimensional (2D) woven and unidirectional (UD) laminates made from high-strength fibres were widely used in soft-body armour development due to their excellent mechanical properties and better fatigue life [14,15]. The high-performance fibres, such as Twaron®, Kevlar®, Dyneema® and Spectra® are among the well-known textile materials extensively used in flexible personnel ballistic protection due to their high resistance-to-impact damage [16–18], high strength, high tenacity, good chemical resistance and lightweight characteristics [19,20]. Various researchers have also investigated the ballistic performances of various layers of different 2D fabrics and UD laminates made of high-performance fibres while developing soft-body armour [21–23].…”

“…Moreover, besides individual fibre properties and woven construction, the response of material towards projectile impact depends on different combined factors while producing a structural response [33]. Among the different influential factors, the yarn properties [34], textile designs and woven construction [35,36], fabric areal density [37,38], target fabric dimensions [39], fabric layer number [32], panel bonding [40] and panel hybridization [16,41] are some of the main factors which played an important role. Moreover, friction between projectile–yarn, yarn–yarn and filament–filament [42,43], sequence and orientations of layers in hybrid panels [44,45], projectile speed and geometry [46–49], shooting angle [50], frame size and clamping pressure [51] are also other influential parameters affecting the ballistic performances and impact responses of materials.…”
