“…As discussed earlier, it is reported that the insertion of a low impedance interlayer alters the characteristics of stress wave propagation in multilayered materials. 43–44,59,60 Therefore, SHPB testing is performed on sandwich coupons to characterize the effect of neat PDMS and CNT-modified PDMS interlayer on the deformation behavior of GFRP under high strain rate loading. As the deformation of GFRP and CGFRP composite is quite similar in Figure 7, only GFRP laminates are used in sandwich coupons.…”

An experimental investigation is carried out to explore the possibility of carbon nanotubes addition and incorporation of polydimethylsiloxane soft interlayer in improving the impact strength and energy-absorbing capability of conventional glass fiber-reinforced plastics. To this end, deformation behavior of glass fiber-reinforced plastics, carbon nanotube-modified glass fiber-reinforced plastics, and glass fiber-reinforced plastics-polydimethylsiloxane sandwich coupons under high strain rate loading are compared using the split-Hopkinson pressure bar testing technique. While neat epoxy is used to process conventional glass fiber-reinforced plastics, the carbon nanotubes-modified glass fiber-reinforced plastics samples are fabricated using 0.5 wt. % carbon nanotube-modified epoxy. The split-Hopkinson pressure bar testing reveals that the addition of carbon nanotubes improves the peak stress and energy-absorbing capacity of the epoxy matrix. The improved impact response of carbon nanotube-modified epoxy translates into enhanced peak stress and energy-absorbing capability of carbon nanotubes-modified glass fiber-reinforced plastics in comparison to conventional glass fiber-reinforced plastics under impact loading. The microscopy analysis of failed composite samples reveals that while glass fiber-reinforced plastics primarily fails at the fiber/epoxy interface, the failure initiates in the epoxy matrix in carbon nanotubes-modified glass fiber-reinforced plastics samples. The impact testing of sandwich samples shows that the insertion of neat and 0.05 wt. % carbon nanotube-modified polydimethylsiloxane interlayer helps to distribute the impact load in a wider domain and thus delays the failure of glass fiber-reinforced plastics sandwich coupons. Moreover, the carbon nanotube-modified polydimethylsiloxane interlayer is better suited to increase the damage resistance and energy-absorbing ability of glass fiber-reinforced plastics. The present study provides a feasible strategy to enhance the failure strength and energy-absorbing capacity of conventional composites using carbon nanotube-modified epoxy and polydimethylsiloxane-based interlayer.

“…Transparent laminates such as laminated glass (LG) has been widely adopted in the automotive engineering and construction sector. LG products are vulnerable to dynamic load [1], such as the pedestrian impact in a car accident, blast load [2] or windborne debris hit on the glass structures [3,4]. The post-fracture capability of LG products [5,6] is worthy of investigation and a rising trend of corresponding reports can be found in recent years.…”

Fiber metal laminates (FMLs) are a class of hybrid materials consisting of several thin metal layers bonded by layers of composite material. In the present study, the ballistic limit, absorbed energy, specific perforation energy and failure mechanism of FML 2/1 (Al/GFRE/Al) and FML 3/2 (Al/GFRE/Al/GFRE/ Al) are numerically and experimentally studied under the high-velocity impact loading using a single-stage light gas gun. In addition, the ballistic behavior of FML 2/1 and FML 3/2 is investigated using three different projectile nose geometries. Numerical simulation of the ballistic tests was performed to determine the residual velocity and the FML panel failure mechanism by using AUTODYN. The results indicated that the highest ballistic limit for FML 2/1 and FML 3/2 was obtained for the conical nosed projectile and the ballistic limit of FML 3/2 was 75.63% higher than FML 2/1. Although the FML 3/2 thickness is ~67% higher than FML 2/1, the specific perforation energy of FML 3/2 is improved by 72.51%, 55.26%, and 89.22% compared to FML 2/1 for blunt, hemispherical, and conical nosed projectiles, respectively.
