“…Reactive materials and their applications are being extensively studied due to the uniquely coupled response of mechanics and chemistry. When impacting the target at enough velocity, the reactive material projectile will be initiated to induce a deflagration reaction, achieving combined damage of the kinetic energy and the chemical energy to the targets . As such, the dramatically structural damage to the targets and the significant ignition enhancement to the combustible or explosive targets will be caused.…”

Quasi-static compression experiments are performed on two kinds of the PTFE/Al/W reactive material specimens, fabricated by means of the cold isostatic pressing but not sintering or the pressing followed by sintering, respectively. The results show that, compared with the pressed specimens, the sintered specimens show higher failure stress and greater fracture toughness. Moreover, the mesoscale failure behaviors are significantly influenced by the sintering technique and the component ratios. There are significantly different bonding and dispersion type of the PTFE matrix between the pressed specimen and the sintered specimen, resulting in the differences of mechanical properties and failure behavior between the two kinds of specimens.

“…In the past decades, much progress on reactive materials has been achieved, especially in their formulation, fabrication, energy release characteristics, and demonstration experiments of their enhanced damage effect . However, due to the low material strength and density, their engineering applications were restricted.…”

“…During the interaction between projectiles and targets, properties of each part and impact conditions are all relevant factors deciding the eventual response of projectiles and targets. Especially for the reactive projectiles, the kinetic impact and chemical energy release are combined during the perforation process [ 19 , 20 ], which brings a challenge in analyzing projectile target interaction. Thus, the perforation behavior and collision mechanism of reactive projectiles are important to be systematically studied and characterized.…”

Perforation behavior of 3 mm/3 mm double-spaced aluminum plates by PTFE/Al/W (Polytetrafluoroethylene/Aluminum/Tungsten) reactive projectiles with densities ranging from 2.27 to 7.80 g/cm3 was studied experimentally and theoretically. Ballistic experiments show that the failure mode of the front plate transforms from petalling failure to plugging failure as projectile density increases. Theoretical prediction of the critical velocities for the reactive projectiles perforating the double-spaced plates is proposed, which is consistent with the experimental results and well represents the perforation performance of the projectiles. Dimensionless formulae for estimating the perforation diameter and deflection height of the front plates are obtained through dimensional analysis, indicating material density and strength are dominant factors to determine the perforation size. High-speed video sequences of the perforation process demonstrate that high-density reactive projectiles make greater damage to the rear plates because of the generation of projectile debris streams. Specifically, the maximum spray angle of the debris streams and the crater number in the debris concentration area of the rear plate both increase with the projectile density and initial velocity.

“…Recently, studies on these reactive materials have mainly examined the energy release characteristics [7,8], the impact initiation behaviors [9,10], and the microstructural and mechanical performance [11,12]. In particular, the penetration performance and enhanced damage effects of reactive material projectiles impacting aluminum plates [13,14,15], covered explosives [16], and fuel-filled tanks [17], as well as the interval rupturing damage effects of reactive-materials filled projectiles to multi-spaced aluminum plates [18].…”

Application of PTFE/Al Reactive Materials for Double-Layered Liner Shaped Charge

et al. 2019

View full text Add to dashboard Cite

The penetration enhancement behaviors of a reactive material double-layered liner (RM-DLL) shaped charge against thick steel targets are investigated. The RM-DLL comprises an inner copper liner, coupled with an outer PTFE (polytetrafluoroethylene)/Al reactive material liner, fabricated via a cold pressing/sintering process. This RM-DLL shaped charge presents a novel defeat mechanism that incorporates the penetration capability of a precursor copper jet and the chemical energy release of a follow-thru reactive material penetrator. Experimental results showed that, compared with the single reactive liner shaped charge jet, a deeper penetration depth was produced by the reactive material-copper jet, whereas the penetration performance and reactive material mass entering the penetrated target strongly depended on the reactive liner thickness and standoff. To further illustrate the penetration enhancement mechanism, numerical simulations based on AUTODYN-2D code were conducted. Numerical results indicated that, with increasing reactive liner thickness, the initiation delay time of the reactive materials increased significantly, which caused the penetration depth and the follow-thru reactive material mass to increase for a given standoff. This new RM-DLL shaped charge configuration provides an extremely efficient method to enhance the penetration damage to various potential targets, such as armored fighting vehicles, naval vessels, and concrete targets.
