By comparing the test performance of metal alloy anti puncture materials and aramid fiber machine woven impregnated anti puncture materials, the differences in anti puncture performance, bending performance, and energy absorption performance between the two were systematically analyzed. The results show that both materials can withstand tool piercing with 24 joules of impact energy, while the metal alloy material can passivate the tool tip but has weaker protection after in-plane penetration;in terms of bending performance, the metal alloy anti puncture layer exhibits better flexibility and bendability, with a required bending force of 20 N~25 N significantly lower than the aramid fiber woven anti puncture layer of 68 N~72 N. In the energy absorption test, the metal alloy anti puncture layer has a slightly better energy absorption ability under blunt impact, attributed to its effective absorption of impact kinetic energy by irreversible deformation. The study provides empirical support for the selection and optimization design of anti puncture clothing materials, and points out the advantages and limitations of the two materials under different protection needs, providing scientific basis for the innovative development of protective equipment.展开更多
