Top 10 Materials for Bulletproof Helmets

Ballistic or Bulletproof Helmet are intended to keep the wearer safe from bullets, physical impact, and shrapnel. The National Institute of Justice tests them for resistance to specific types of ammunition and assigns them a rating, such as NIJ Level IIIA or NIJ Level IIIB.

During the war on terror, the military began employing the Modular Integrated Communications Helmet (MICH), which was later called the Advanced Combat Helmet (ACH). It provides Level IIIA protection while reducing weight by half a pound by utilizing more sophisticated Kevlar materials and cuts around the helmet to enable user mobility and improve acoustics and compatibility with communication systems.

1. Kevlar

Kevlar is a form of aramid fiber that has been braided to create a material that is both strong and flexible. It is twenty times stronger than steel and outperforms specialty metal alloys.

Kevlar can be found in a wide range of products such as Bulletproof Material, including protective garments, bullet-resistant textiles, and other high-performance gear that must withstand extreme abuse. It outperforms other types of fibers in many ways and is a superb choice for a wide range of applications.

One of the most noticeable advantages of Kevlar is its ability to withstand the impact and kinetic energy of a bullet. This implies it will deflect the bullet before it reaches the wearer's head, potentially saving lives.

Another advantage of Kevlar is that it is extremely durable and resistant to abrasion. This is vital for a variety of applications, particularly in the military and industrial areas, where abrasion is always a problem.

Finally, Kevlar is light and comfortable to wear. As a result, it is the primary material used in ballistic helmets.

Its primary application is in bulletproof vests for military and special forces personnel, as well as for civilian protection. However, it is also employed in other industries such as boat construction and aerospace manufacturing. It is also known for its heat resistance, which is essential in many of these industries.


Because it is lighter than steel and has a high ballistic penetration resistance, ultra-high molecular weight polyethylene, or UHMWPE, is a great choice for bulletproof helmets. It also has a high energy absorption capacity and a low breaking elongation.

UHMWPE is often used in high-end ropes, cords, tethers, fishing line, sailcloth, and other applications that demand a high tensile strength and low density, in addition to bulletproof armor.

UHMWPE fibers are perfect for ballistic impact-resistant armor due to their extraordinarily high strength, directional orientation, and linearity. They are also chemical and heat resistant, with excellent abrasion and cutting resistance.

However, because of their low coefficient of friction, they are prone to separating under ballistic impacts, allowing a bullet to penetrate through the armor. The employment of a resin binder to glue the fibers together solves this difficulty.

Researchers have also experimented with micro-sized dimples on UHMWPE to reduce friction and wear performance. These dimples are often made up of little square or ellipse designs that are created utilizing laser technology.

These dimples have been demonstrated to increase the tribological characteristics of UHMWPE considerably. They reduce friction forces by 50%, and the surface roughness of textured specimens is twice that of untextured specimens.

UHMWPE wear resistance can be increased further by irradiating it with electron beams and adding unsaturated additives. These additives can assist UHMWPE in increasing the cross-linking of terminal double bonds, resulting in improved wear performance.

3. Aramid

Aramid (also known as aromatic polyamide) is a high-performance fiber with five times the tensile strength of Kevlar and exceptional flame resistance. It is also resistant to a wide range of organic solvents and is extensively utilized in military composite materials and body armor.

Aramid is utilized in prusik slings, rappel backups, and other sorts of military gear or Bulletproof Shield that require toughness, in addition to ballistic helmets. An aramid sling's sheath and core are comprised of tightly woven fibers that do not stretch or deform when subjected to abrasion or heat.

Aramid also has strong UV adsorber qualities, which prevent it from sun damage and deterioration. However, because aramid is hygroscopic and can absorb water, it must be protected from moisture and air impurities.

While there are various varieties of ballistic helmets, each one is designed to defend against specific bullet types. A PASGT helmet, for example, offers minimum protection for most rounds, however a MICH/ACH or FAST helmet is more adaptable and may be used with a variety of accessories and communications devices.

Comfort pads, adjustable chin straps, and a quick-adjust headband are all characteristics to look for in a tactical helmet. These characteristics will assist you in keeping your helmet secure and comfortable during prolonged battle scenarios.

The Atomic Defense FAST Combat Helmet is an excellent choice for anyone looking for maximum protection and a comfortable fit. It is built of a tough material that can protect you from bullets as diverse as 44 Magnum, 9mm, and 45 cal. The foam cushioning is fully adjustable to provide a precise fit, and the rounded shell of the helmet deflects or absorbs bullets that impact your head.

4. Polycarbonate

Polycarbonate is a strong material that is utilized in a wide range of products. It's also found in military gear and helmets.

It's an amorphous thermoplastic, which means it may be worked on and reshaped without using heat. This enables it to retain its hardness and strength for an extended period of time, even when subjected to high temperatures.

This material has a wide range of applications, including ballistic windows, which serve to prevent gunshots from piercing a structure or home's window. It can also be utilized in various applications, such as visors to shield the eyes from flying debris and particles.

Another great application for this material is bulletproof helmets. Soldiers and anyone who require additional bullet protection can use these helmets.

These helmets are available in a number of shapes and colors, and they are made to be comfortable to wear. They are also lightweight and easily removable as required.

These helmets' visors are composed of polycarbonate, which can help prevent bullets from striking the head. This can lessen the severity of a concussion and other side effects that may arise after a strong head hit.

The visors are extremely resistant to damage, allowing them to be placed outside for years without issue. They should, however, be thoroughly inspected for signs of damage before use. This will keep them from being abused and will increase their longevity.

5. Thermoplastic Polyurethane

TPU (Thermoplastic Polyurethane) is a robust and lightweight polymer capable of withstanding high-speed impacts. It can also handle high temperatures and pressure, making it an excellent choice for helmets.

Thermoplastic polyurethane is a highly adaptable substance that can be molded into virtually any shape. It has high tensile and burst strength, as well as resilience and flexibility. It is also stress and humidity resistant, and can survive temperatures as low as 122 degrees Fahrenheit (50degC).

Another advantage of TPU is that it has a very high initial tensile modulus, indicating that it is quite robust. This enables it to resist heavy loads and recover fast from them.

TPU is utilized in a variety of products, including surfboards and other equipment that must withstand a great deal of stress and force. It is also water and saline resistant, making it ideal for surfers.

TPU also offers excellent ballistic resistance, which is vital for military and law enforcement applications. It is very good for preventing rifle bullet penetration.

This can be accomplished by constructing a helmet shell out of a series of fiber layers. The helmet's outside, middle, and inner fiber layers can be made of abrasive, woven, or non-woven fibers. A resin matrix is used to glue the fibers together.

The helmet's exterior, middle, and inner fibers can be made of a number of materials, including aramid fibers and polyethylene fibers. To make a high-performance ballistic helmet, aramid fibers can be coated or impregnated with a thermoplastic polyurethane matrix. To give further protection against bullets, the polyurethane can be impregnated with ceramic plates.
