Product Description

Kevlar Round Tubes (KFRP Round Tube) — Aramid Fiber Wound · Ultra-Tough Impact Resistance · Lightweight Ballistic-Grade

Kevlar Round Tubes are hollow cylindrical profiles reinforced primarily with DuPont™ Kevlar® 29/49 or equivalent aramid fibers. These fibers are impregnated with high-strength epoxy or vinyl ester resin and cured via continuous filament winding or pultrusion-winding composite processes. With a density of only 1.44 g/cm³ and up to five times the specific strength of steel, they offer exceptional impact resistance, delamination resistance, and thermal durability from −170 °C to +250 °C. Ideal for applications requiring ballistic protection, explosion resistance, vibration dampening, and lightweight structural integrity.

Kevlar Round Tubes deliver unmatched impact resistance and lightweight performance with high‑tensile Kevlar fiber construction—ideal for demanding structural applications.

• Top Advantages: 5× higher impact strength, 60 % lighter than steel, excellent ballistic and abrasion resistance.
• Applications & Value: Perfect for protective enclosures, UAV components, and safety equipment—enhancing durability and reducing weight.

Key Advantages

1. Ultra-High Toughness: With an elongation at break of 3–4%, they absorb 3–4× more impact energy than equivalent carbon fiber tubes.
2. Thermal Stability: Operates reliably at 200 °C long-term and retains 80% strength at 250 °C for short durations.
3. EM-Safe & Insulated: Non-magnetic and electrically insulating—ideal for MRI, radar, and naval applications.
4. Superior Durability: Resists cutting, corrosion, salt spray, sea water, and organic solvents.
5. Custom Strength Design: Adjustable fiber winding angle from 15° to 75° for optimized axial or hoop strength.
