“…For instrument thought, the stopping harm/damage to the front plate is caused by the dynamic vitality effect of the receptive shot. With expanding of the effect speed or diminishing of the front plate thickness, the active vitality of the remaining shot, the boundary development area of the section cloud and the deflagration response weight amid entering the back plate would increment continuously [15].…”

The three dimensional spacer textures, comprise of two bi-directional woven texture surfaces, which are mechanically associated with vertical sewed heaps. The three dimensional spacer textures can be made of glass fiber, carbon fiber or basalt fiber. The Three Dimensional Composites are classified based on the different factors depending on the orientation of the yarn, the yarn sets and the geometry. The three dimensional composites have multiple layers and hence they overcome delamination, which is a common defect in two dimensional composites. Nevertheless, these composite materials have relatively lower transverse properties and also, have size and thickness limitations.This literature reviews on several important published literatures on three dimensional composite materials. The review studies the numerous effects that lead to the failure of the composite material.

“…Generally, these materials stay inert until subjected to a sufficiently strong mechanical stimulus to undergo fast burning and explosion which releases enormous chemical energy [1][2][3][4][5][6]. The unique intensive dynamic loading induced hot spots form within received extensive attention as potential structural materials for explosives [7][8][9][10] and propellants [11][12][13]. Polytetrafluoroethylene filled by aluminum and tungsten particles (PTFE/Al/W) is a typical formula applied for current reactive materials studies [10,14].…”

“…One of the traditional methods to obtain different densities is to change the formulation, for example, changing the massive ratio of inert metal (W particle) for the PTFE/Al/W reactive materials. Most researchers have considered reactive materials as a continuum with uniform bulk density [1,7,10]. Actually, the bulk densities of reactive materials will be close to their theoretical maximum density via a pressing/sintering process; however, the distinction between bulk densities and theoretical maximum density still exists due to the inner structural pore.…”

In this research, the bulk density homogenization and impact initiation characteristics of porous PTFE/Al/W reactive materials were investigated. Cold isostatic pressed (CIPed) and hot temperature sintered (HTSed) PTFE/Al/W reactive materials of five different theoretical maximum densities were fabricated via the mixing/pressing/sintering process. Mesoscale structure characteristics of the materials fabricated under different molding pressures were compared while the effect of molding pressures on material bulk densities was analyzed as well. By using the drop weight testing system, effects of the theoretical maximum densities (TMDs), drop heights and molding pressures on the impact initiation characteristics were studied. Quantitatively, characteristic drop heights (H50) for different types of materials were obtained. The two most significant findings of this research are the density homogenization zone and the sensitivity transition zone, which would provide meaningful guides for further design and fabrication of reactive materials.

“…In order to improve the penetration performance on hard targets, a large number of scholars have studied the effects of liner materials and structures of shaped charge . In the research of liner materials, reactive materials have been widely concerned since it can release chemical energy again after penetrating target and increase the penetration hole diameter.

To improve penetration performance of the classical conical shaped charge, a bore-center annular shaped charge (BCASC) was designed and effects of key parameters on its formation and penetration into concrete targets were investigated numerically and experimentally. As a result, suitable parameters of the BCASC, which comprehensive consideration of penetration hole diameter and depth into concrete targets, were provided. Subsequently, tests of the optimized BCASC penetration into single-layer and doublelayer concrete targets were performed. The results indicate that, for all the cases, the diameters of the rear crater are larger than that of the front ones. The influence of factors h (standoff distance) and f (the radial distance between the center of the inner and outer liner wall) on the diameters of the front crater, the penetrating tunnel, and the rear crater are greater than that of other factors. The diameters of the front crater and the penetrating tunnel decrease with the increase of factors h and f. The penetration depth of optimized BCASC into concrete exceeds 3.0 times of the charge diameter (D). Hole diameters of penetrating tunnels are larger than the charge diameter. For the single-layer concrete target, the hole diameter of the penetrating tunnel is 2.26D. And, for the double-layer concrete target, the hole diameters of the first and second layers are 1.41D and 1.33D, respectively.
