基于对材料特性和防弹机理的认识,设计了由600D腈纶、无纺布、Al2O3陶瓷和高强PE材料构成的陶瓷基复合靶板,靶板防护面密度ρA为92 kg/m2,尺寸为300 mm×300 mm×35 mm,用现役12.7 mm穿甲燃烧弹考核了靶板防护能力,尤其是探讨了PE在背面不受约束情况时中弹后的行为。结果表明:靶板结构是可行的,可防住V25为810 m/s的现役12.7 mm穿甲燃烧弹,PE层有优良的防二次效应的性能,而靶板结构有较大的改进空间。在靶试和讨论分析的基础上,给出了靶板结构改进的设计方案。
Based on the knowledge of material properties and bullet-proof mechanism, a ceramic-based composite target consisting of 600D acrylic, non-woven fabric, Al2O3 ceramic and high-strength PE was designed. The target surface protection density ρA was 92 kg / m2 and the size was 300 mm × 300 mm × 35 mm. The current 12.7 mm armor-piercing bomblets were used to evaluate the protection ability of the target. In particular, the behavior of the PE after the projectile was unobstructed on the back was discussed. The results show that the target structure is feasible and can prevent active service 12.7 mm armor piercing projectile with a V25 of 810 m / s. The PE layer has excellent anti-secondary effect performance, while the target plate structure has more room for improvement . On the basis of the target test and the discussion and analysis, the design scheme of improved target structure is given.
