I. The main materials of the shell

Bulletproof helmet shell is its main protective structure, bear the direct impact from the outside. Currently on the market the mainstream shell materials mainly include metal, non-metal and metal and non-metal composite materials.

II. The inner shell material

Inner shell material is usually used to enhance the structural stability of the helmet shell and wearing comfort. Common inner shell materials include polymer, lightweight alloy and so on. These materials not only provide sufficient support, but also ensure the softness and fit of the helmet interior, effectively reducing the impact of direct head injury.

III. the cushioning layer material

Cushioning layer is a key part of the bulletproof helmet, it can effectively absorb and disperse impact energy, reduce the head injury. Common cushioning layer materials include foam, rubber and so on. These materials have good elasticity and energy-absorbing properties, and can be quickly deformed when the bullet or shrapnel impact, the energy will be dispersed and absorbed.

IV. fiberglass and chrome steel jade

As a composite material, fiberglass reinforced plastic is also used in bulletproof helmets. It combines the advantages of glass and resin, with high strength and corrosion resistance. Chrome steel jade is a very high hardness material, commonly used to enhance the helmet's local protective ability.

V. Polycarbonate and polyurethane

Polycarbonate and polyurethane are two common plastic materials, also used in the manufacture of bulletproof helmets. Polycarbonate has high impact resistance and transparency, while polyurethane has good elasticity and wear resistance. These materials play an important supporting role in the manufacture of helmets.

VI. Aramid and PE fibers

Aramid and polyethylene fibers are common composite materials in ballistic helmets. Aramid fibers have high strength, high modulus, high temperature resistance and excellent chemical resistance, while polyethylene fibers have good impact resistance. The combination of these two materials makes the helmet both lightweight and highly bulletproof.

Ⅶ. Polyethylene and polypropylene

Polyethylene and polypropylene are two widely used polymer materials that also play an important role in the manufacture of ballistic helmets. These materials have good mechanical properties and chemical stability, so that the helmet can be in a variety of environments to maintain a stable protective performance.
