Industrial Carbon Fiber Fabric Precision Reinforcement For Automotive

Product Specification

Carbon Fiber Unidirectional Fabric : Precision Reinforcement For Aerospace , Automotive & Structural Engineering​

​​1. Product Introduction​​

Carbon Fiber Unidirectional Fabric (UD) is engineered for maximum strength and stiffness in a single directional orientation. Composed of continuous carbon fibers aligned parallel to one axis, this material delivers unparalleled performance in structural applications where directional load-bearing is critical. Key features:

• ​​Directional Strength​​: Up to ​​5,000 MPa tensile strength​​ along the fiber axis, ideal for aerospace, automotive, and wind energy sectors

  .

• ​​Lightweight​​: Density as low as ​​1.5–2.0 g/cm³​​, reducing overall component weight by 30–50% compared to metals

  .

• ​​Fatigue Resistance​​: Maintains integrity under cyclic stress, making it suitable for high-stress environments like aircraft wings

  .

• ​​Thermal Stability​​: Operates effectively up to ​​300°C​​ without significant degradation

  .

• ​​Corrosion Resistance​​: Impervious to acids, alkalis, and moisture, ideal for marine and industrial applications

  .

​​2. Manufacturing Process​​

1. ​​Precursor Processing​​:

   • Polyacrylonitrile (PAN) fibers undergo stabilization (200–300°C) and carbonization (1,000–3,000°C) to form graphite-like structures

     .

2. ​​Fiber Alignment​​:

   • Carbon filaments (5–25 µm diameter) are aligned unidirectionally using automated spreading machines.

3. ​​Resin Impregnation​​:

   • Fibers are coated with epoxy, polyester, or vinyl ester resin to enhance adhesion and durability

     .

4. ​​Layer Consolidation​​:

   • Multiple UD layers are stacked and stitched or bonded to form multi-directional composites

     .

5. ​​Curing​​:

   • Heat and pressure (120–150°C, 0.5–1.0 MPa) ensure full resin curing and void elimination

     .

​​3. Usage Precautions​​

• ​​Handling​​:

  • Wear ​​PPE (gloves, goggles)​​ to avoid fiber irritation; use sharp tools cautiously to prevent breakage

    .

• ​​Resin Compatibility​​:

  • Match UD type (e.g., standard modulus vs. high modulus) with epoxy, polyester, or vinyl ester resins

    .

• ​​Curing Conditions​​:

  • Maintain ​​120–150°C​​ and ​​0.5–1.0 MPa pressure​​ during curing to eliminate voids

    .

• ​​Storage​​:

  • Store in dry, ventilated areas (humidity <60%); avoid prolonged UV exposure to prevent coating degradation

    .
