Ultra-Lightweight Aramid-Carbon Fiber Blend for Ballistic Protection
Carbon Fiber
Composition: A high-strength, high-modulus fiber composed of 90%+ carbon atoms, with diameters of 5–10 µm (finer variants down to 5 µm).
Structure: Crystalline carbon layers (graphene-like sheets) with irregular interlayer bonding, preventing slippage and enabling exceptional tensile strength (~5,650 MPa)
Carbon fiber and aramid fiber (e.g., Kevlar®) are high-performance synthetic materials. Carbon fiber consists of thin, strong crystalline filaments (5-10µm diameter) with exceptional strength-to-weight ratio (5x stronger than steel at 1/4 the weight). It withstands temperatures up to 2,000°C and is used in aerospace, automotive, and sports equipment.
Aramid fiber features heat-resistant aromatic polyamide chains, offering superior impact resistance (5-6x stronger than steel) with flame resistance up to 560°C. Its lightweight, cut-resistant properties make it ideal for bulletproof vests, helmets, and protective gear.
Key differences:
• Carbon fiber is rigid/stiff; aramid is flexible/tough
• Carbon conducts electricity; aramid insulates
• Carbon excels in structural applications; aramid dominates impact protection
Both fibers revolutionize industries requiring lightweight durability, though carbon fiber is typically more expensive. Modern composites often combine both materials for optimized
