Imagine a material that combines feather-light weight with rock-like strength while maintaining electrical conductivity—a substance that seems straight out of science fiction. This material exists as carbon fiber, and today we examine one of its specialized forms: chopped carbon fiber.

What Is Chopped Carbon Fiber?

While conventional carbon fiber appears as continuous filament strands, engineers developed chopped carbon fiber by precisely cutting these filaments into shorter segments. This processing isn't arbitrary—it follows strict manufacturing protocols to maintain performance characteristics.

The fundamental properties of chopped carbon fiber derive from its parent material's quality. Its key advantage lies in superior dispersion capabilities and simpler processing methods, enabling applications where continuous fibers prove impractical.

Technical Specifications

The analyzed chopped carbon fiber exhibits these critical performance metrics:

• Carbon Content: 95% - Ensuring optimal material performance through near-pure carbon composition
• Tensile Strength: 3,500 MPa - Capable of withstanding approximately 350kg of force per square millimeter
• Elastic Modulus: 228 GPa - Exceptionally high stiffness that resists deformation
• Density: 1.75 g/cm³ - Significantly lighter than steel (7.85 g/cm³) for weight-sensitive applications
• Electrical Resistivity: 1.0-1.6 Ω·cm - Provides measurable conductivity for specialized uses
• Fiber Diameter: 7 μm - Approximately one-tenth the thickness of human hair
• Cross-Section: Circular - Enhances uniform dispersion in composite matrices
• Bulk Density: 0.4 g/cm³ - Affects material handling and mixing characteristics
• Standard Lengths: 1mm-100mm - Customizable for specific application requirements
• Resin Compatibility: Optional pre-mixing available for simplified processing

Industrial Applications

Chopped carbon fiber serves diverse industrial sectors through multiple applications:

• Plastic Reinforcement: Enhances mechanical properties in automotive components and electronic enclosures
• Conductive Materials: Enables antistatic coatings and electromagnetic shielding solutions
• Friction Components: Improves performance in braking systems and clutch mechanisms
• Concrete Fortification: Increases crack resistance and longevity in construction materials

Market Considerations

Priced at approximately $230 per kilogram (¥1,680/kg), the material's value proposition depends on specific application requirements. When performance enhancements justify the investment—particularly in weight reduction and strength optimization—the premium becomes economically viable. Buyers should conduct thorough supplier evaluations to ensure quality consistency.

As industries increasingly prioritize advanced materials, chopped carbon fiber demonstrates significant potential across manufacturing sectors. Its unique combination of properties continues to enable innovative solutions where traditional materials reach performance limitations.
