Aramid flame-retardant fabric used for tire carcass fabric and motorcycle riding suits

Characteristics of Aramid Woven Fabric:

1. High specific strength and specific modulus

Specific strength (strength/density): 5-6 times that of high-quality steel, 2-3 times that of glass fiber.

Specific modulus (modulus/density): 2-3 times that of steel and glass fiber.

Mainly used for bulletproof and stab-resistant purposes.

2. Strong impact resistance and energy absorption capability

Fiber tensile fracture: consumes a large amount of energy.

Friction between yarns: yarns slide and deform within the fabric structure.

Stress wave transmission: rapidly disperses impact force across the entire fabric surface.

The fibers themselves have extremely high toughness. When high-speed projectiles (such as bullets or shrapnel) hit the fabric, the woven fabric absorbs and disperses energy through the above mechanisms, effectively preventing penetration.

3. Excellent heat resistance and flame retardancy

Thermal decomposition temperature reaches about 500°C.

Does not melt at high temperatures; carbonizes when exposed to fire, forming a stable protective layer.

Note: Its long-term heat resistance (about 160-180°C) is slightly lower than meta-aramid (Nomex), but it has better instantaneous high-temperature resistance and flame retardant performance.

4. Low density and lightweight

Density is about 1.44 g/cm³, much lighter than metal materials. Protective gear made from it greatly reduces the burden on the wearer, improving flexibility and comfort.

5. Good dimensional stability and fatigue resistance

Low creep under stress, shape stable. Resistant to repeated bending and twisting, with a long service life.

6. Certain chemical resistance

Good resistance to organic solvents and fuels, but poor tolerance to strong acids, strong alkalis, and ultraviolet light; requires post-treatment for protection.

Applications of Aramid Woven Fabric:

1. Personal safety protection

Bulletproof vests/plates (Soft/Hard Armor): Use multiple layers of woven fabric laminated together to absorb the kinetic energy of bullets (handgun rounds, shrapnel). Standard equipment for law enforcement and military personnel.

Bulletproof helmets: Replace traditional steel, providing equal or better protection at a lighter weight.

Stab-resistant clothing/cut-resistant gloves: Used in security, law enforcement, glass processing, machinery manufacturing, and other industries to effectively resist penetration and cutting by sharp objects such as daggers, needles, and glass shards.

Blast blankets/blast barriers: Used by bomb disposal personnel to contain blast shock and shrapnel within a controlled area.

2. Industrial and composite material reinforcement

Rubber reinforcement:

Automotive hoses: such as brake lines, air conditioning hoses, turbochargers, providing high strength and low elongation to ensure safety.

Conveyor belts: Used as skeleton material in heavy-duty applications like mining and ports, tear-resistant with long service life.

Tire carcass fabric: Used in high-performance tires to reduce weight and rolling resistance.

High-strength ropes: Used for ship mooring, aerospace (such as helicopter slings), and large engineering structure towing, offering high strength and light weight.

Friction sealing materials: Used to manufacture highly durable clutch plates, brake pads, gaskets, etc.

3. Sports and leisure products

High-performance sports equipment: Used in rowing boats, kayaks, archery, high-end bicycle rims, tennis rackets, skis, etc., providing extremely high strength and impact resistance while achieving ultra-lightweight.

Protective gear: Used in motorcycle riding suits, racing suits, climbing ropes, etc., offering excellent abrasion and cut protection.

4. Aerospace and marine

Aerospace composite materials: Used as reinforcing fibers in manufacturing UAV fuselages, satellite components, aircraft interior panels, etc., significantly reducing weight.

Hull reinforcement: Used in composite hulls of high-performance patrol boats and racing boats, reducing weight and improving speed and fuel efficiency.
