Performance of kevlar fibre-reinforced rubber composite armour against shaped-charge jet penetration

Abstract

The protective capability of the Kevlar fibre-reinforced rubber composite armour (KFRRCA) at different obliquities is studied using depth-of-penetration experiments method against a 56 mmdiameter standard-shaped charge. Efficiency factors are calculated to evaluate the protection capability of the KFRRCA at different obliquities. Meanwhile, an X-ray experiment is used to observe the deformation, fracture, and scatter of the shaped-charge jet as it penetrates the composite armour. Finally, scanning electron microscopy (SEM) is used to analyse the effect of the Kevlar fibrereinforced rubber for the composite armour to resist jet penetration. The results showed that the KFEECA can be used as additional armour, because it has excellent protection capability, and it can disturb the stability of the middle part of the shaped charge jet (SCJ) obviously especially when the armour at 30°and 68° obliquities.

Numerical Material Model for Composite Laminates in High-Velocity Impact Simulation

“…Experimental study is another significant method because it is not only closer to the real physical process but also is the base of the other methods. Many experimental studies are reported in the literatures (Zhu et al, 1992;Wang et al, 2005;Babu et al, 2007;Zu et al 2015), which give insight of the anti-ballistic mechanism of composites, and provide a large amount of data for the future studies. Numerous intervening parameters as mentioned above, make the impact issue of composite materials are rather complicated.…”
