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.
However today a new material called SPECTRA has been released on the market and SPECTRA is more flexible, lighter and stronger than KEVLAR. This new substance is changing the face of bullet proof wear for police and the military, but what are the differences and the big advantages of SPECTRA?
Let's first examine the structure of each of the two materials. Kevlar is a high strength, high performance fiber that, despite its many years of use in bullet proof clothing, is still not entirely understood. The best description of how it is believed to function is that the molecules form into sheets that then stack themselves around the center of a fiber like spokes. The idea behind using this as a bullet proof material was to stack several layers of the material together in a weave pattern.
The weaving would then "catch" the bullet by allowing the fibers to break apart layer by layer and absorb the velocity, slowing the bullet to a stop as it also dulled and flattened from striking the material. However, this was mostly effective when bullets were slower and had less total velocity, making them easier to stop. Now, our troops and law enforcement officials face much more technically advanced weaponry with bullets flying at higher speeds and constructed from harder metals.
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.
Spectra is a completely new and different technology. Spectra is about 40% lighter than Kevlar which makes it a lot more comfortable. Spectra is not been woven which only helps reducing even more the weight and bulk as there is no need for several layers. - 16492
