Applications of nanocomposite ballistic materials

The nanocomposite fibers can offer maximum strength combined with minimum weight, and are finding an ever-increasing array of uses in the performancedemanding life protection sector. They are available as both continuous filament yam and unidirectional sheet (UD) for use against ballistic threats. 

UD products offer high levels of protective ability whilst keeping weight to a minimum. When used in personal protective equipment and clothing, UD provides for increased comfort and is therefore comfortable to wear in extreme circumstances and over long periods of time. 

When fiber is ineorporated into body armor, its light weight and flexibility allow the wearer an unparalleled freedom of movement without compromising protective value. Additional armor plates made with fiber UD can be molded to fit the shape and size of the wearer s body and inserted into garments. This allows protective products to be tailor-made to fit the wearer, enhancing both comfort and confidence for those in the line of fire. 

Fiber UD can also be incorporated into custom-shaped armor panels for vehicles, offering improved design flexibihty and protection. Fiber UD is a light-weight, cost-effective alternative to metal armor to protect occupants from direct fire, landmine and improvised explosive device (lED) threats. The lower weight of solutions based on fiber UD improves the vehiele s performance and payload, and facilitates easier installation of the armor. 

However, the biggest limitation of these nanocomposite fibers is difficulty with production on an industrial scale. As explained in the previous section, the properties of fibers are highly related to the extent of dispersion of nano-fillers. However, nano-filler dispersion is time-dependent for mass production.
