Warp-knitted anti-ballistic aramid fabric for spall-liners

Teijin Aramid : 03 September, 2013  (New Product)
Teijin Aramid is launching a new anti-ballistic spall-liner solution at the DSEI show (London ExCel, September 10-13). The new fabric, Twaron T765, offers cost-effective ballistic protection in ground vehicles. It is ideal for protecting military vehicles in high-threat situations, but it can also provide protection in civilian vehicles against lower-level threats. Spall liners made of Twaron T765 can be used for protecting vehicles such as tanks, trucks and armored personnel carriers and its passengers.
Spall liners provide extra support for the outer faces of armoured vehicles. In the event of an impact or explosion on the surface, they help to prevent or reduce fragmentation of the vehicle structure. This is important, as fragments flying around the interior can often cause more injury to passengers than the explosion itself. Twaron T765 is ideal for use in composite armour designed for armouring vehicles, especially in combination with steel, ceramic, aluminum and titanium.
 
Usually, fabrics used for spall liners are woven structures. Twaron 765, however, uses warp-knitting technology. This state-of-the-art-process, which is also used to create advanced 3D glass-fibre constructions, results in a heavier and sturdier fabric. This means that fewer layers are needed to meet the high ballistic specifications. In addition, less material has to be purchased, processed and treated during production. All in all, this can lead to substantial savings and enable more economical ballistic protection.
 
Twaron T765 has been tested rigorously according to STANAG 4569, levels 1-4. Combined with other materials, it protects against  bullets, fragments, Improvised Explosive Devices (IEDs), mine blasts and projectiles.
