Throughout history various
materials have been used as body armor for protection against combat injuries
especially to protect vital organs. The science of body armor has come a long
way from earlier eras when leather, wooden shields, chain mail, and cumbersome
plate mail (metal armor used for edged weapons protection) were the chosen means
of protection. Currently, we now have type 3a body armor down to the type 4
body armor which provides the highest level of protection.
Older methods and materials for body armor had a real purpose and were effective measures for their time. Developments of new weapon systems have been matched in one way or another by the various levels and types of body armors. USA records show that attempts in making better body armor were made by engineers as early as the first part of 1900s. Actual use of bullet proof vests in 1930s has been fully documented as well. These early models were either not effective against high velocity ballistics, were too cumbersome or were not cost effective to produce more. _
Then came the modern body
armor. This new type of body armor focused on the use of silk woven into the
armor as a protective property. The silk models were eventually deemed
ineffective against high velocity rounds and were too expensive to manufacture on
a large scale.
Soon after, the National Institute of Justice research identified new materials that could be woven into lightweight fabric from the development of lightweight body armor that employed DuPont’s Kevlar ballistic fabric into prototypes. Reports concluded that the new ballistic material was effective in providing a bullet resistant garment that was lightweight and suitable for full-time use. Until such came a time when new materials arises from Spectra to other silk materials. Due to this, NIJ needed to have armor classifications such that people can have a chart to see what type of protection they need. They can choose from type 1 to type 3a body armor for soft body armor group and type 3 to type 4 body armor for the hard body armor group. |
