One type of ballistic substance is Kevlar. This material is made up of filaments that are woven and has a density 70 kg/m3. It is designed to have a Back Face Signature of 40 mm. When a projectile comes into contact with the material, it will have an enormous impact on the surface beneath. The maximum force transmitted is about 11 kN. This material is among the most durable available.
Para-aramid fibers are a different kind of Ballistic Materials. These are continuous lengths of interwoven fibers which have a high tensile strength and a low density. They are used in body armor, bulletproof vests and even for e-cigarette lighters. PVC and PBO are two other ballistic materials. Para-aramid fibers, however, are the most well-known due to their low density and resistance to many chemicals.
Another type of ballistic material is ceramic, which is made of clay that is heated to high temperatures. When it is used to protect human beings, it can be layered with Kevlar or fiberglass. When struck, ceramic fragments into powder. The fiberglass absorbs energy and deflects bullets. It can be placed between steel plates to distort rounds and capture bullets. It is important to have a mixture of hard and soft ballistic materials to protect your rifle.
Para-aramid materials and unidirectional polyethylene laminates show an irreversible change in ballistic performance. The primary cause of failure in unidirectional polyethylene laminates can be thermal. This leads to a significant decrease of the front layer performance. Damage from thermal is another reason for the back face signature. Unidirectional polyethylene laminates have a greater perforation rate than Twaron (r) inserts woven. In this instance the most effective hybrid insert composition is to place Twaron(r) para-aramid material prior to the Dyneema UD.
Hard armor for vehicles can stop all fragments but textile vests can only stop fragments at a certain speed. They are therefore not appropriate for military personnel as they are light weight. However, they still provide fragment protection particularly against the 2-4-16-64 grain series. The weight of a textile vest is an important factor when comparing the benefits of various vests.
Furthermore, a core of hard material can also be used to mimic human tissue. Most rifle ammunitions have steel cores. They are hardened to 100-130 HB. The hardness of these cores can help determine their impact resistance. While a core that is hard can endure high energy rates however, a soft core is unable to block the penetration. Therefore, it’s recommended to select composite materials with high density.
Bulletproof panels are custom-tailored and made from materials designed to withstand the impact of bullets. They can also absorb bullet energy, making them ineffective. Steel bulletproof materials are durable and only a few millimeters thick. Steel bulletproof panels deform under the force of a bullet hitting them. This stops the bullet from reaching the target. Bulletproof materials are strong and durable, ensuring that no bullets hit the target.
