Carbon fiber fabric is used for weight reduction in racing car bodies and for reinforcing infrastructure projects.

Carbon fiber woven filament fabric, commonly referred to simply as "carbon fiber cloth" or "prepreg blank," is a fabric created by interweaving thousands of ultra-fine carbon fiber filaments—typically categorized as "filament bundles," such as 3K, 6K, or 12K—in specific weaving patterns like plain, twill, or satin. It serves as the foundational material for manufacturing high-performance carbon fiber composite components.

Characteristics of carbon fiber fabric

1. Exceptional Mechanical Performance

High strength and high modulus: Carbon fiber is more than five times stronger than steel, yet its density is only one-quarter that of steel. Its specific strength (strength-to-density ratio) and specific modulus (modulus-to-density ratio) rank among the highest of any existing materials.

Lightweight: This is one of its most significant advantages. Using carbon fiber composites can dramatically reduce product weight, which is crucial in the aerospace and automotive industries.

2. Highly customizable

Carbon fiber fabric exhibits varying mechanical properties depending on the direction. By adjusting the weaving pattern and ply angles—such as stacking at 0°, 90°, or ±45°—engineers can precisely "design" the material's strength and stiffness to match the load conditions of the part, optimizing performance while minimizing waste.

3. High fatigue resistance

Carbon fiber composites exhibit exceptional resistance to dynamic loads, impacts, and vibrations, with fatigue strength significantly higher than that of metallic materials such as steel and aluminum. This means they are far less likely to fail under prolonged, repetitive stress conditions.

4. Low thermal expansion coefficient

Carbon fiber has an extremely low coefficient of thermal expansion in the fiber direction, and it even contracts at low temperatures. This ensures that carbon fiber products maintain remarkable dimensional stability in both high- and low-temperature environments, preventing significant deformation due to temperature changes.

5. Excellent corrosion resistance

Carbon fiber itself is highly chemically inert, making it resistant to reactions with acids, bases, salts, and other media. Its corrosion resistance far surpasses that of metals, which makes it exceptionally suitable for harsh environments such as the chemical industry and marine applications.

6. Other Features

Conductivity: Possesses excellent electrical conductivity and can be used for electromagnetic shielding (EMI/RFI shielding).

X-ray penetrability: Essentially transparent to X-rays, making it highly useful in medical equipment such as CT bed plates.

Aesthetics: The distinctive black woven texture exudes a strong sense of technology and futurism, often used for exterior components.

Applications of Carbon Fiber Fabric

1. Aerospace

Applications: Aircraft wings, fuselages, tail surfaces, fairings, helicopter rotor blades, and aerospace components (such as satellite supports and rocket engine casings).

Weight reduction delivers significant fuel-economy benefits, while high strength and stiffness ensure flight safety.

2. Automotive Industry

Racing cars (F1) and supercars: Used to manufacture monocoque bodies, chassis, drive shafts, bumpers, and more, pursuing the ultimate in lightweight design and rigidity.

High-end civilian vehicles: Used for roofs, hoods, interior panels, wheel hubs, and more, balancing weight reduction with enhanced performance.

Future trend: As costs decrease, gradually expand into new energy vehicles to extend battery range.

3. Sports and Leisure Equipment

Applications: Golf clubs, tennis rackets, badminton rackets, bicycle frames (road bikes, mountain bikes), fishing rods, rowing boats, paddleboards, helmets, skis, and more.

Lightweight design can enhance athletic performance, while high stiffness delivers superior power transmission and handling.

4. Industry and Energy

Wind Power Generation: Manufacturing ultra-large wind turbine blades requires materials that are lightweight yet highly durable, capable of withstanding long-term fatigue loads.

Robotics and Automation: When applied to robotic arms, reducing weight translates into faster motion speeds and lower energy consumption.

Pressure vessel: A tank used to store high-pressure gases (such as natural gas, hydrogen).

Basic building reinforcement: Carbon fiber fabric (bonded with specialized resin) can be used to strengthen concrete structures such as bridges, buildings, and piers, enhancing their load-bearing capacity and seismic resistance.

5. Consumer Electronics and Healthcare

Consumer electronics: Used for laptop casings, phone cases, drone bodies, and more, offering lightweight, high strength, and a premium tactile experience.

Medical devices: Used in X-ray bed panels, prosthetics, orthotics, surgical robot arms, and more, leveraging their lightweight, high-strength, and X-ray penetrability properties.
