Analysis of the enhancement effect of UHMWPE backplate thickness on the penetration resistance of aluminum composite panels

College of Mechatronics Engineering, North University of China, Taiyuan 030051, Shanxi, China

摘要

摘要: 为研究超高分子聚乙烯（ultra-high molecular weight polyethylene, UHMWPE）背板厚度对铝复合板抗钨球侵彻效果的影响，利用数字图像相关方法（digital image correlation method, DIC）与X射线电子计算机断层扫描（computed tomography, CT）得到UHMWPE受到冲击后的动态响应及局部破坏。建立钨球以不同速度侵彻Al/UHMWPE复合板的有限元模型，研究不同冲击速度下UHMWPE背板厚度对复合靶板吸能性能的影响，所用背板厚度为1.6~20 mm。结果表明：铝板在冲击作用下发生绝热剪切破坏，正交铺设纤维层产生纤维凸起和分叉应变带。随着背板厚度增大，纤维层由剪切破坏向拉伸破坏过度，纤维层应变带由十字形转变为X形。UHMWPE板厚度的增大有效地阻碍了铝块塞体运动，从而增加了破片侵彻铝板的时间与动能消耗。UHMWPE背板厚度对吸能性能影响呈先快速上升至阈值，后缓慢下降的趋势，说明PE板到达一定厚度后，通过增加厚度的方法来提升其吸能性能的作用有限。

Abstract: Ultra-high molecular weight polyethylene (UHMWPE) fibers are widely used in explosive fragment protection due to their high modulus, high strength, and low density. To study the effect of UHMWPE backplate thickness on the penetration resistance effect of aluminum composite panel, the digital image correlation method (DIC) and computed tomography (CT) were used to obtain the dynamic response and local failure of UHMWPE. A finite element model of a tungsten ball penetrating an Al/PE composite plate with different speeds (500, 1000, and 1500 m/s) was established, and the simulated results were found to be in good agreement with the experimental results. The influence of PE backplate thickness on the energy absorption performance and strain of the composite target plate was mainly studied, and the thickness of the backplate was 1.6-20 mm. The results demonstrate that the aluminum plate undergoes adiabatic shear failure under the impact, and the fiber layers are laid orthogonally to produce fiber bulges and bifurcated strain bands under tension. The fiber bulge and cross-shaped strain band bifurcation phenomenon occur when the fragments penetrate the orthogonally laid fibers. With the increase of the PE plate thickness, the main failure of the fiber layers changes from shear failure to tensile failure, and the strain band of the fiber layers changes from cross shape to X shape. Increasing the thickness of the PE plate hinders the movement of the plug body of the aluminum block, thereby increasing the time and kinetic energy consumption of the fragment penetrating the aluminum plate. When the impact velocity is 500, 1000 and 1500 m/s, the optimal areal density absorption energy thickness respectively is 6.4, 12, and 16 mm, and the surface density energy absorption respectively is 14.55, 49.51 and 98.07 J·(kg·m²). The influence of PE composite plate thickness on energy absorption performance first rises rapidly to the threshold and then slowly decreases, this result shows that increasing the PE plate thickness is limited in improving its energy absorption performance after reaching a certain thickness.
