What Material Is Inside A Bulletproof And Stab-proof Suit?

Body armor can be divided into three types: soft body, hard body and soft-hard composite. The materials of soft body armor are mainly high-performance textile fibers. These high-performance fibers have much higher energy absorption capabilities than ordinary materials, giving the body armor the bulletproof function. And because this type of body armor generally adopts a textile structure, it has considerable The softness is called soft body armor. Hard body armor is made of metal materials such as special steel plates, super-strong aluminum alloys, or hard non-metallic materials such as alumina and silicon carbide as the main body armor materials. The body armor made from them is generally not flexible. The softness of the soft and hard composite body armor is between the above two types. It is lined with soft materials and hard materials as the panels and reinforcement materials. It is a composite body armor.
The bulletproof layer is made of metal, fiberglass, ceramics, nylon, Kevlar and other hard and soft materials singly or in combination, so that the warheads and shrapnel can bounce off or become embedded, and dissipate the impact kinetic energy to play a protective role.
Stab-proof clothing is made of a stab-proof material blended with ultra-high-strength ultra-high-density polyethylene chopped strand yarn and aramid chopped strand yarn. It is also called a stab-proof vest or stab-proof garment. It can effectively block knives. It fully protects the human body's trunk and internal organs from being stabbed, cut, and chopped with cold weapons such as knives and daggers. The material selected for this garment has excellent properties such as high breaking strength and large elastic modulus.
