The main differences between stab-proof suits and bulletproof vests lie in their functions, materials and structures. Stab-proof suits focus on protecting against cuts, slashes and punctures, while bulletproof vests are mainly used to protect against bullets and shrapnel. In terms of materials, puncture-proof suits mostly use ultra-high strength fiber fabrics, while bulletproof vests incorporate various materials such as metal and ceramics.

I. Functional Differences

Stab-proof suits: Mainly used to resist the attacks of stabbing, cutting and chopping from cold weapons such as knives and daggers, protecting the human trunk and internal organs from harm.

Bulletproof vests: Mainly used to protect against the harm of bullets and shrapnel to the human body, they can absorb and dissipate the kinetic energy of warheads and shrapnel, and prevent penetration.

Ii. Material Differences

Puncture-proof suits: They are mostly made of puncture-proof materials blended with ultra-high strength and ultra-high density polyethylene chopped strand and aramid chopped strand, or composed of several layers of high-performance materials, such as Kevlar non-woven fabric, etc.

Bulletproof vest: It is mainly composed of a cover and a bulletproof layer. The coverings are commonly made of chemical fiber fabrics, while the bulletproof layer is composed of materials such as metal, ceramic sheets, fiberglass reinforced plastic, nylon, Kevlar, and ultra-high molecular weight polyethylene fibers.

Iii. Structural Differences

Puncture-proof suit: The special woven structure combined with the excellent performance of ultra-high strength fibers endows the puncture-proof suit with the functions of anti-cutting and anti-puncture. Its fibers are closely and irregularly arranged, forming a layered network structure, which can effectively bind and intercept the punctured object.

Bulletproof vest: The fiber arrangement of a bulletproof vest is relatively regular. Its purpose is to consume the energy of bullets through processes such as stretching or cracking of the material. In addition, bulletproof vests may contain hard inserts, such as metal, ceramic or high-performance composite plates, to enhance the bulletproof effect.
