Bulletproof helmets are mainly classified into three categories based on their materials: metal, non-metal and composite materials. The following are the specific differences among these three types of bulletproof helmets:
1. Bulletproof helmets made of metal
Youdaoplaceholder0 material properties :
It is mainly composed of metal materials (such as special steel plates), featuring high strength and hardness.
Protective performance :
It can effectively resist the impact of bullets or shrapnel and provide a relatively high level of protection.
However, due to the high density of metal materials, bulletproof helmets are often heavy, which may affect the mobility and comfort of the wearer.
Other features :
It has excellent waterproof, moisture-proof and fireproof performance.
It has relatively high durability, but its protective performance may gradually decline due to metal fatigue.
Ii. Non-metallic bulletproof helmets
Material properties :
It is mainly made of high-strength and high-modulus chemical fibers as the basic raw materials and is compounded through special processes.
Protective performance :
It can also provide effective bulletproof protection, and due to the lower density of non-metallic materials, helmets are often lighter.
Some non-metallic helmets also achieve uniform distribution of bulletproof performance through special traction techniques, enhancing the overall protective effect.
Other features :
It has good air permeability and high wearing comfort.
It has less interference with electromagnetic waves and is suitable for occasions where communication needs to be kept unobstructed.
Iii. Bulletproof helmets made of Composite materials
Material properties :
It combines the advantages of both metallic and non-metallic materials and is composed of multiple materials. For instance, fiber-reinforced resin-based composites combine a resin matrix and reinforcing fibers.
Protective performance :
It has excellent protective performance and can withstand the impact of various types of ammunition.
Through reasonable material combination and structural design, a balance between lightweight and high strength has been achieved.
Other features :
It has excellent corrosion resistance and high-temperature resistance.
Customized design can be carried out according to specific needs to meet the protection requirements in different scenarios.
