Advantages And Disadvantages Of Ballistic Liners And Hardening Materials

Ballistic Spall Liners, lightweight linings, can be placed close to the vehicle’s interior surface to limit the spall caused by projectile penetration. They are made of non-metallic materials such as ceramic fiber or high-tensile-strength woven fabrics. They are typically employed in conjunction with armor plates to enhance the ballistic performance of the vehicle. They also have some disadvantages.

The topmost layer of the liner is comprised of fabric plies. The fabric plies disperse force along projectile’s trajectory in the direction of the lateral. The bottom layer is composed of elongating martensite sheet steel, which stretches outwardly and acts as a shock absorber. After impact with the bottom layer the less forceful projectile fragments and remains trapped within the bulge.

A spall liner shield consists of three or more layers. The first, third and fifth layers are fabric sublaminates composed of a very thin ply fabric that is joined together with the use of a resinous adhesive. While the fabric sublaminates possess excellent bonding properties, they do split. The second and fourth layers of the liner shield are made of steel. The base layer that delaminates is located on the wall surface that is not protected and can be placed just a few inches away from the wall.

What are Spall Liners are necessary to protect vehicles from bullet fragmentation damage. If the liner isn’t protected with a shield, a stray bullet could cause significant damage. The vehicle can continue to function normally thanks to the armor added to it that stops hitting. AFV manufacturers offer a variety of armor add-ons or liners to protect their vehicles from such dangers. These are able to be customized to meet the threat scenario.

The outer layer of the liner is made of three plies of high-tensile-strength fabric. The outer layer is elongated, and is layered in precisely the same way as the base and intermediate layers. This is the way a Spall Liner works. In contrast to fabric liners, it can resist forces without breaking. So, if your ship is experiencing a significant amount of force, it may be beneficial to utilize Spall Liner.

The intermediate layer that forms the first layer of the liner is susceptible to cracking and cannot be penetrated with high-speed projectiles. The intermediate layer may be bent to fracture in these instances. The resulting delamination effect creates an opening in the outer layer. The cracks in the outer layer’s flexibility. The intermediate layer 22 has a tendency to stretch, making it not a good candidate for absorber of high-speed impact.
