Can bulletproof material prevent cutting
When watching military programs, you may see that soldiers will wear a bulletproof vest. In order to protect them from injury, soldiers of any country will distribute it when entering the battlefield. With the continuous development of science and technology, its types are more and more, and its protective performance is stronger and stronger, Can bulletproof vests prevent knives? The answer is unexpected. Many people don't believe it.
It can be said that it provides protection for soldiers, but have you ever thought about whether it can resist the scratch of the knife? Firstly, the manufacturer of bulletproof materials will introduce its types to you. At present, it can be divided into three categories: soft, hard and soft hard composite. In these three categories, most of the soft ones are made of Kevlar fiber. Although this material can resist the threat of small caliber guns, the effect is not very good for those sharp cold weapons.

After all, the shear stress generated when the knife cuts on its surface can still be cut. Hard ones, also known as insert plates, are mostly made of steel plates or ceramic sheets. Therefore, when facing bullets, the effect is very good, and when facing cold weapons, the effect is also very good, but the disadvantage is that they are too heavy, which will cause great consumption of soldiers' physical fitness!
Therefore, many soldiers now choose soft and hard composite ones that are more comfortable to wear and better defensive. This kind of soft bulletproof clothing is generally installed with insert plates at important parts of soft bulletproof clothing. The effect is very good, and the weight is much lighter than that of pure hard ones. Although this kind of weapon has good effect in the face of cold weapons, if the stabbed has no insert plates, It's still easy to get hurt.
