The Difference Between Stab-resistant Clothing And Body Armor

Ordinary body armor is made of Kevlar material. When the bullet hits the body armor, the extremely tough Kevlar fiber will transfer the kinetic energy of the bullet to the entire body armor, so that the bulletproof effect can be achieved. That is to say, the principle of body armor is actually to share the impact kinetic energy of the warhead to each Kevlar fiber, so the body armor will be completely scrapped after one shot. But what the tool produces is shear stress, the direction of the force is perpendicular to the fiber material, and the energy density of the tip of the knife is much higher than that of the bullet. Anyone who has studied materials knows that the resistance of fiber material to the shear stress in the vertical direction is the worst. It can even be said that it has no effect, so for knives, body armor has no choice but to sigh.
Good stab-proof clothing is based on the principle of using softness to overcome rigidity and combining rigidity and softness for protection. It not only pays attention to protective performance, but also pays more attention to wearing comfort. The flexible stab-resistant material developed by High Armor Protection adheres to this concept and is developed. Stab-proof clothing pays more attention to human body wearability.
