The Role of Aramid Fiber in Body Armor

Aramid fiber has been the backbone of soft body armor for decades. Here is how it works.

How Aramid Stops Bullets

When a projectile hits aramid layers, the high-tenacity fibers absorb and spread the kinetic energy across the panel, deforming the bullet and bringing it to a stop.

Aramid vs UHMWPE

While both stop handgun rounds, aramid is preferred for its heat resistance and lower cost, while UHMWPE offers lighter weight for the same protection.
