In the past being protected by body armor was synonymous for bulk, weight , uncomfortable and mass. However over the years, many manufacturers like Dupont have gone a long way to improve the traditional body armors for police and the military especially when they introduced KEVLAR. KEVLAR has increased the protection and comfort of the body armor while reducing the mass and weight.
Today, there is a new substance in use called Spectra, a composite material that is stronger, lighter, and more flexible than Kevlar, which is changing the face of bullet proof wear for our troops and police forces. What are the major differences between Kevlar and Spectra, and what are the big advantages of the latter?
Kevlar is a high strength, high performance fiber that, despite its many years of use in bullet proof clothing, is still not entirely understood. If we examine the structure of the two we see that Kevlar is made from a high strength and high performance fiber. The idea behind using this as a bullet proof material was to stack several layers of the material together in a weave pattern. A more or less exact description is difficult but you should try to see it is that the molecules form into sheets that then stack themselves around the center of a fiber like spokes.
In the past when bullets had less velocity and were not constructed from extremely hard materials, Kevlar did a fine job. When a bullet hit a bullet proof vest the different layers of Kevlar reduced the velocity and flatted the bullet while braking layer after layer. This was a very effective way to stop those bullets but today bullets are made of harder materials and the technically very advanced weaponry give the bullets a very high speed.
This means that Kevlar vests are stretched to capacity and sometimes even penetrated completely by these forceful weapons. The only answer with this material is to thicken the layers of weave, which make the material even bulkier, heavier, and less flexible.
Since Spectra is a completely new and different technology , there is no need for layers due to the fact that Spectra is not a woven fabric. It is about 40% more lighter than Kevlar which makes it very useful for comfortable bullet proof vests - 16747
