Aramid Fiber Fabric (Aramid Fiber) is a high-performance synthetic fiber with ultra-high strength, heat resistance, and chemical corrosion resistance. With a tensile strength 5-6 times that of steel but a density of only 1.44 g/cm³, it is widely used in ballistic protection, aerospace, new energy vehicles, 5G communications, and other high-end fields.
What is Aramid Fiber Fabric?
Aramid fiber (Aramid Fiber, full name Aromatic Polyamide Fiber) is a high-performance synthetic fiber with aromatic rings as the backbone. At least 85% of the amide bonds (-CO-NH-) in its molecular chain are directly connected to two aromatic rings. This unique molecular structure gives aramid fiber ultra-high strength, high modulus, heat resistance, and chemical corrosion resistance.
Core Properties
- Ultra-high Strength: Tensile strength reaches 2.8-3.6 GPa, 5-6 times that of high-quality steel
- High Modulus: Tensile modulus 70-130 GPa, excellent dimensional stability
- Heat Resistance: Long-term use temperature 180-200°C, short-term can withstand 450-500°C
- Low Density: 1.44 g/cm³, 78% lighter than steel, 20% lighter than fiberglass
- Chemical Resistance: Resistant to acid, alkali, and organic solvent erosion
- Flame Retardant: Limiting Oxygen Index (LOI) >28%, excellent self-extinguishing properties
- Impact Resistance: Energy absorption capacity is 2-3 times that of carbon fiber
Aramid Fiber Types and Technical Characteristics
