Influence of different back laminate layers on ballistic performance of ceramic composite armor

Abstract

This paper mainly reported a new type of ceramic composite armor with a back laminate of Ti6Al4V/UHMWPE/Ti6Al4V against the 12.7 mm armor piercing projectile at a velocity of 818 m/s. The mechanism of the whole ceramic composite armor against the projectile, and the function of each layer in the back laminates were systematically investigated around the experiments and numerical simulations. The results indicated that the outermost Ti6Al4V layer provided support for the UHMWPE layer, leading to the UHMWPE layer displaying the extremely high buffer performance during the impact process. Meanwhile, the middle UHMWPE layer also had an energy balance function between the first and outermost Ti6Al4V layers to cause small damage in the back laminate layers. Thus, this configuration contributed to absorb or dissipate the more energy of the impact projectile, successfully preventing the perforation of the projectile.

Desempenho balístico de estruturas multicamadas à base de alumina/epóxi

“…Tais propriedades qualificam as cerâmicas para aplicações em blindagem balística. O desenvolvimento de blindagens cerâmicas tornou os sistemas de proteção mais leves e eficientes em comparação com as blindagens metálicas convencionais [1][2][3]. As blindagens cerâmicas geralmente são compostas por duas partes: uma camada de cerâmica apoiada e uma placa de apoio metálica (liga de alumínio ou aço) ou um polímero reforçado com fibra [4].…”

Numerical study of the influence of gaps between tiles and backing type on overall high-velocity impact performance of a ceramic-faced protective structure

“…These works became the basis for all further studies in this area. Since then, the impact loading of high-strength fabrics and composites [6][7][8][9][10][11][12][13], ceramics [14][15][16][17][18][19][20], as well as their combinations [21][22][23][24][25][26][27][28][29], has been widely studied using both experimental and numerical approaches.…”

Analytical and experimental study of high-velocity impact on ceramic/nanocomposite targets

“…Velocity-time history of the projectile shows a good agreement with the Chocron-Galvez numerical model. Liu et al [14] studied the influence of different back laminate layers (Ti6Al4V/UHMWPE/Ti6Al4V) on the ballistic performance of ceramic composite armor around the experiments and numerical simulation. Krishnan et al [15] discuss a numerical modeling of ceramic composite armor systems with a backing made of ultra-high-molecular-weight polyethylene (UHMWPE).…”
