A stab-resistant substrate was designed and realized with a triangular pyramidal structure, inspired by the biological armor model in nature. The stab-resistance behavior and dynamic response mechanisms were studied through numerical simulation and experimental testing of a knife impacting a substrate, and an optimal structural design was obtained accordingly, with a tilted angle of 22.5° and optimal thickness of 1.2 mm. It was shown that the triangular pyramidal structure generated twice the internal energy of the knife than the flat substrate due to the dispersing effect of the structure. The force parallel to the inclination caused a significant scratch on the substrate surface, while the force perpendicular caused obvious substrate deformation. A new riveting method was used to form the total layer, which passed the GA 68–2008 standard. The stab-resistant clothing coupled with the reduced wearing burden could provide effective protection and avoid fatal injuries on security personnel working in dangerous environments. The method provided may enlighten the future design and manufacturing of stab-resistant clothing.

在自然界中的生物装甲模型的启发下，设计并实现了具有三角形锥体结构的防刺基底。通过数值模拟和刀具冲击基板的实验测试，研究了其防刺性能和动力响应机理，并据此获得了最佳的结构设计，倾斜角度为22.5°，最佳厚度为1.2mm。结果表明，由于三角形锥体结构的分散作用，其产生的刀的内部能量是平坦基板的两倍。平行于倾斜度的力会在基板表面上造成明显的划痕，而垂直方向的力会导致基板发生明显的变形。一种新的铆接方法用于形成总层，并通过了GA 68–2008标准。防刺服加上减轻的穿着负担可以提供有效的保护，并避免在危险环境中工作的安全人员的致命伤害。提供的方法可能会启发防刺服的未来设计和制造。
