“…In the case of the specimens with v f of 2.0%, a part of the stored energy released results in a rebound with the decrease of the load and deflection, owing to their sufficient ductility to absorb the impact energy. A similar observation was also reported by Dey et al [2].…”

“…Unfortunately, since concrete is a brittle material, the energy absorption capacity under such high strain-rate loadings is very poor, which causes several concerns. Therefore, many researchers [1][2][3][4][5][6][7] have performed studies to enhance its energy absorption capacity under impact and blast by using various reinforcements, such as fibers (i.e., steel fibers, polymeric fibers, and carbon fibers), fiber-reinforced polymers, steel reinforcing bars, etc.…”

Improvement of impact-resistant property of glass fiber-reinforced composites by carbon nanotube-modified epoxy and pre-stretched fiber fabrics

Glass fiber-reinforced plastic composites (GFRPs) are often suffered to impact loadings; it is essential to improve its damage-resistant properties and understand the energy absorption mechanisms. In this work, the low-velocity impact behaviors of GFRPs were investigated in consideration of epoxy resins modified with 0, 0.4, and 0.75 % multi-walled carbon nanotubes (MWCNTs) by weight content and pre-stretched fabric at 0, 1.27, and 2.47 kg weight. In comparison with pure GFRPs sample, MWCNT-modified specimens are effective in improving the impact resistance under impact energies at 9, 16, and 22 J in terms of reduced damage factor and enhanced perforation threshold. Microscopic fractographic analysis indicated that the incorporation of MWCNTs in epoxy matrix offered additional mechanisms through breakage, bridging, and pull-out of carbon nanotubes to favor load transfer effect, prevent crack propagation, and thus dissipate more energy. The dynamic thermo-mechanical analysis proved that MWCNTs improved the storage modulus and glass transition temperature of the composites. In addition, the pre-stretched GFRP composites showed more impact resistant than the non-stretched ones through instant load transfer effect.

“…Part of the input energy is absorbed by the test specimen and remaining energy is dissipated by friction or transferred to the supports of the tested sample after the impact event [12]. The potential energy, which depends on mass of the impactor and the drop height, can be calculated by the next equation:…”

Abstract. Generally, cement composites like high-performance concrete (HPC) are very brittle. The resistance to the impact loading of the HPFRC and the HPFRC reinforced by the textile reinforcement are compared in this article. The samples (0.56 × 0.1 × 0.1 m) were experimentally tested in three-point bending, by using horizontal impact machine. The better resistance of the textile reinforced HPFRC is obvious from the collected data (impact force, acceleration of hammer and acceleration of the tested sample).
