Hypothesis
The study aims to analyze the impact behavior of aramid fabric using numerical simulation.
Conclusion
The study found that a 20-layer aramid fabric panel can meet NIJ protection requirements against specific projectiles at certain velocities, while fewer layers or higher velocities lead to failure.
Supporting Evidence
- The 20-layer fabric panel stopped the 9 mm Luger projectile at 398 m/s without perforation.
- At higher velocities, the fabric showed rapid stress wave propagation and failure.
- Numerical simulations provided insights into the mechanisms of fabric damage during impact.
Takeaway
This study shows that thicker aramid fabric can better protect against bullets, especially when they hit at high speeds.
Methodology
The study used finite element simulations to model the impact of projectiles on aramid fabric panels.
Limitations
The study may not account for all real-world variables affecting fabric performance under ballistic impact.
