Is there a difference between bulletproof vests and stab proof suits? Since bulletproof vests can prevent bullets, isn't it even more important to prevent stabs? The fundamental difference between them is their functionality, one is bulletproof and the other is knife proof. The former is mainly used for the protection of bullets, while the latter is mainly used for the protection of knives and pointed tools.
Bulletproof vests, also known as bulletproof vests, bulletproof vests, bulletproof vests, bulletproof suits, individual protective equipment, etc., are used to protect the human body from bullet heads or fragments. A bulletproof vest mainly consists of two parts: a jacket and a bulletproof layer. Covers are commonly made of chemical fiber fabrics. The bulletproof layer is composed of metal (special steel, aluminum alloy, titanium alloy), ceramic sheets (corundum, boron carbide, silicon carbide, alumina), fiberglass, nylon, Kevlar, ultra-high molecular weight polyethylene fiber, liquid protective materials, and other materials, forming a single or composite protective structure. The bulletproof layer can absorb the kinetic energy of bullet heads or fragments, and has a significant protective effect on low-speed bullet heads or fragments. It can reduce damage to the chest and abdomen of the human body by controlling certain depressions.
Anti stab clothing, also known as anti knife clothing, anti knife clothing, or anti knife clothing, has functions such as anti knife cutting, anti knife cutting, anti knife stabbing, anti scratching of objects with edges, wear resistance, and theft prevention. When wearing a knife protective clothing, it can protect the wearer from cuts, scratches, rubs, and cuts if worn or cut, cut, cut, scrape, scrape, or cut with a sharp knife (blade, sharp object, etc.).
The bulletproof mechanism of bulletproof vests is as follows: high-strength and high modulus fiber fabric layered soft armor absorbs the kinetic energy of projectiles through fiber breakage and fabric structure changes. However, the force generated by tool stabbing is shear stress, with the direction of the force perpendicular to the fiber material, and the energy density of the blade tip is much higher than that of the bullet, so the fiber material has the worst resistance to vertical shear stress.
The anti stab principle of anti stab clothing: The special woven structure combined with the excellent performance of ultra-high strength fibers makes it have functions such as anti cutting, anti cutting, and anti stab.
So there is a big difference between the two, and in real life, one can choose to use bulletproof vests or stab proof clothing according to the actual situation.
