Ballistic Fabrics

Ballistic Fabrics

1. Nylon

   • How it's made
     • By using organic acids and ammonia to create a chain. Adipic Acid and Hexamethylene Diamine are used.
   • How strong it is
     • About 3.5 times stronger than steel wire.
   • Environmental Issues
     • Not environmentally friendly since if melted, it releases toxic fumes. Most of the time it ends up in the landfill.
   • Main Uses
     • In civilian vest and some military vests where large firearms aren't usually involved. Also used in consumer products like luggage.
   • Structure

2. Kevlar

   • How it's made
     • By using organic acids and ammonia to create a chain. Paraphenylenediamine and Terephthaloyl are used.
   • How strong it is
     • More than 8 times stronger than steel wire.
   • Environmental Issues
     • Not environmentally friendly since it's very heat resistant and will decompose before melting. Most of the time it ends up in the landfill.
   • Main Uses
     • In military ballistic vests and some civilian vests.
   • Structure

3. What can it stop?

   • Without metal or ceramic plates
     • Handgun rounds, spalling and knives
       • Kevlar will also stop small rifle rounds
   • With metal or ceramic plates
     • Handgun rounds, small and most large rifle rounds, shrapnel, spalling as well as knives.
       • Kevlar with plating will also stop some larger rifle rounds like .50 BMG Armor Penetrating rounds.

4. Reusability

   • Not reusable since fibres are broken or shifted making a weak spot.
