Low-velocity impact and static behaviors of high-resilience thermal-bonding inter/intra-ply hybrid composites

Shear behavior of a shear thickening fluid-impregnated aramid fabrics at high shear rate

“…The agility and mobility of soldiers wearing such soft armor depend on the performance-to-weight ratio of the materials. Especially polyamide fibers (aramid fibers), which have strong primary (the amide bonding in single fiber chain) and secondary bonding (hydrogen bonding between the fiber chains) in molecular structure, are used for soft armor applications due to the high strength and toughness [6][7][8][9][10][11][12]. Thus, many studies have focused on improving the fiber properties, in particular stiffness and strength [13,14] and heat resistance [15].…”

Experimental and numerical investigation of interply hybrid composites based on woven fabrics and PCBT resin subjected to low-velocity impact

“…Aktas et al [21] investigated the effect of stitch pattern on the impact and post impact behavior of eight ply woven-knit hybrid composite plates. Yan et al [22] prepared inter/intraply hybrid composites reinforced with Kevlar nonwoven/glass woven fabrics, and impact tests were performed on the prepared panel. Wang et al [23] tested the impact properties of a lightweight hybrid composite.…”

“…It is found that hybrid composites have higher interlaminar shear, tensile, as well as compression after impact properties by using hybridization approach [10][11][12][13][14]. While researches on dynamical characteristics of hybrid composites are usually comprised of mechanical experiments such as low-velocity impact test [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. In this regards, Hosur et al [15] carried out the experimental investigation to determine the response of four different combinations of hybrid laminates under low-velocity impact load.…”

Using unwrapped filament tows to strengthen sandwich composites: Puncture and bursting resistance

“…The materials were processed with needle punching and thermal bonding in order to form compound fabrics, whose static and dynamic puncture resistances were then evaluated [9]. Yan et al conducted two studies on sandwich composites containing glass fabrics and the composites were evaluated for their mechanical properties [10,11]. Based on the study by Valenc¸a et al, composites that were composed of Kevlar fabrics and glass-fiber fabrics had higher mechanical strength, bending property, and impact energy [4].…”
