Advantages

Greatly improved penetration resistance

Fiber incorporation absorbs projectile kinetic energy and delays crack propagation, markedly reducing penetration depth, especially at low fiber dosages.

2% fiber content optimal for impact resistance

Considering both penetration depth and crater dimensions, 2% fiber content yields the best protection; crater size is markedly reduced, with only marginal further improvement at higher dosages.

Applications

• Protective engineering：For structures that directly withstand projectile impact with reduced penetration.
• High-performance concrete：Combines high strength and impact toughness for demanding loading conditions.
• Fiber-reinforced composites：Short fibers bridge cracks, enhancing dynamic fracture toughness.
• Military protection：For bunkers and military fortifications that resist high-velocity projectile penetration.
