One of Dyneema's main uses is for armored vehicle protection. Its incredible strength and resistance to extreme and changing weather conditions make it an ideal addition to vehicles in dangerous situations. Its ability to be molded to various forms allows Dyneema to be used in a variety of vehicles for military, law enforcement and civilian protection applications. Depending on the type of situations that Dyneema will be used for it can be obtained for either soft ballistics, like handguns, or hard ballistics, like antitank projectiles, land mines.
Dyneema can be used in two different ways for vehicle protection, as either spall liner or as a panel. In its form as spall liner, Dyneema works as an extra layer of protection against a ballistic threat to a vehicle. Spall liner is used to protect vehicle occupants by catching and absorbing the ballistic itself, or metal fragments that came off of the vehicle due to the explosion. When Dyneema is used as panel it can protect against stronger ballistic threats such as antitank projectiles and tank-penetrating projectiles. The panels can be custom shaped and easily cut to the design specifications of the vehicle.
By themselves or combined Dyneema has the potential to protect against a range of ballistic threats including direct gunfire from an AK47, improvised explosive devices (IEDs), rocket-propelled grenades (RPGs), land mines or explosively formed penetrators (EFPs).
Compared to armor plating, armor made with Dyneema that has a steel or ceramic strike plate is 50 to 75 percent less dense than steel armor [source: SoldierMod.com]. Because it is extremely light and moldable a vehicle equipped with Dyneema doesn't have to sacrifice maneuverability or design, or change the center of gravity in order to protect against an explosion or gunfire.
Dyneema has also been implemented into an invention that protects not only the occupants of a vehicle but also the vehicle itself from a direct explosion. The structural blast chimney uses Dyneema to take the initial blast of an explosion and channel it towards the center of the vehicle and then up and away from it. The design of the chimney along with the Dyneema's impact absorption allows the vehicle stay firmly planted on the ground and intact during an explosion, protecting occupants from sound, heat and sheer force of the explosion.
