“…Typically, the pull-out force of the Kevlar/STF fabrics increased with the pull-out speed, which was consistent with the shear thickening property of STFs. Meanwhile, lots of investigations on the ballistic properties of the composite have been reported [18,[25][26][27][28][29]. Park et al [28] focused on the energy absorption of STF-treated fabric composite under high speed (>700 m/s) impact and studied the change of energy absorption value with the impact velocity by changing the number of Kevlar layers and area density.…”

“…Aramid fibers are one of the popular materials for bulletproof armor designs (Haro et al., 2016). Compared with steels, the aramid fabrics have a high ratio of ballistic performance/weight ratio (Laha and Majumdar, 2016).…”

Flexible fabrics have been widely used in body armor designs. Here we report ballistic impact damage of stacked cross-plied composite fabric and cross-plied laminated panels. The ballistic impact behaviors of stacked cross-plied composite fabric and cross-plied laminated panel have been tested with fragment-simulating projectiles under the strike velocity 550–600 m/s to explore the influence of the layers combination of fabric target on ballistic impact. Two types of macroscopic anisotropy continua finite element models based on fabric targets structures are established to analyze the ballistic mechanism of stacked cross-plied composite fabric and cross-plied laminated panels. The impact damage morphologies and energy absorptions have also been compared between the tests and finite element analysis results. We have found the stacked fabric construction absorbed more energy than their counterpart cross-plied laminated panel, while the laminated panel shows better structural integrity and stability during ballistic penetration.

“…The STF can be used as impact absorption and/ or damping material due to its shear thickening phenomenon induced by a dramatic change of viscosity. Park et al (2014), Gurgen et al (2017), Lee et al (2003), Decker et al (2007), and Haro et al (2016) applied STFs in liquid body armor to enhance its flexibility and protectiveness. Zhou et al (2016), Zhao et al (2018), Wei et al (2018), and Lin et al (2019) examined the damping characteristics of STF-filled dampers.…”

Lightweight carbon fiber reinforced polymer composite structures with high stiffness are at risk of resonant vibration. Our study proposes a methodology to reduce this risk by passively improving the damping ratio of carbon fiber reinforced polymer composite structures. We developed shear thickening fluid hybrid composite structures by applying polyimide tubes filled with shear thickening fluid having rheological properties into a composite laminate. In order to verify the proposed methodology, carbon fiber reinforced polymer–based shear thickening fluid hybrid composite beams were fabricated, and modal tests were subsequently performed to investigate their dynamic characteristics. The results revealed that the damping ratios for the initial six vibration modes of the carbon fiber reinforced polymer–based shear thickening fluid hybrid composite beam increased by 38%–174%; however, their Young’s modulus and tensile strength, respectively, decreased by 11.25% and 14.08% when compared to those of normal carbon fiber reinforced polymer composite beams. We believe that the proposed methodology to improve the damping ratio will contribute in reducing the risk of vibration resonance of carbon fiber reinforced polymer composite structures in various applications.
