| Abstract |
Based on existing ballistic penetration experimental studies, this work investigates the antipenetration performance of interlayer hybrid composite panels composed of kevlar and uhmwpe (ultra-high-molecular-weight polyethylene). The results validate that Kevlar exhibits superior suitability as the impact-facing layer compared to uhmwpe. Building on this finding, we employed ballistic limit velocity test and numerical simulation methods to analyze the damage modes and anti-penetration performance of panels penetrated by 1.1 g fragments. Additionally, the penetration process was simulated using Ls-dyna, enabling the prediction of interlayer hybrid ratios with superior anti-penetration performance under three specific conditions. The underlying mechanisms were further elucidated. The results showed that under the condition of equal areal density, the hybrid composite panel with kevlar as the impact-facing layer mixed with uhmwpe demonstrates enhanced anti-penetration performance when the mass ratio of kevlar to uhmwpe is approximately 25%. Under the condition of identical layer count, the panel achieves superior ballistic resistance when the mass ratio of kevlar to uhmwpe reaches 70%. Under the condition of constant thickness, the optimal anti-penetration performance is observed when the mass ratio of kevlar to uhmwpe is 53%. Using materials with high shear strength on the surface layer of the target plate and materials with high tensile strength and high elongation at break on the back layer can better enhance the synergistic effect between the hybrid composite material layers. |
