Chopped Carbon Fiber Properties
- High strength and stiffness: Very strong and rigid, so it keeps its shape well and provides solid structural support without bending easily.
- Lightweight: Extremely light compared to metals and many other materials, while still offering much higher strength.
- High temperature resistance: Performs reliably even under high heat without losing its stability or strength.
- Corrosion and wear resistant: Doesn’t rust or get easily damaged by chemicals, and holds up well even after long-term use.
- Electrical and EMI shielding properties: Conducts electricity and can help block or reduce electromagnetic interference and signal noise.
- Low thermal expansion and good compatibility: Hardly changes size with temperature changes, and bonds well with resins and other composite materials for manufacturing.
Your Trusted Chopped Carbon Fiber Manufacturer in China
Chopped carbon fiber is a type of carbon fiber composed of short carbon fiber segments or fibers, typically ranging from a few millimeters to a few centimeters in length. These fibers are produced by cutting or shredding continuous carbon fiber filaments. These carbon fiber filaments are often compounded with resins or other materials, retaining many of the superior properties of continuous carbon fiber, such as high strength, high stiffness, and lightweight.
YAOCHEN chopped carbon fiber is the preferred choice for many customers in a variety of applications. Whether you need tensile strength, tensile modulus, or both, our chopped carbon fiber consistently delivers optimal performance. We guarantee high product quality through rigorous process and production control.
Chopped Carbon Fiber of Various Specifications
Choosing chopped carbon fiber depends on what you’re making. Think about whether you need easy mixing, good resin flow, more strength, or better overall performance. Then just pick the right fiber length to get the best balance of strength and easy processing.
3mm is the shortest type of chopped carbon fiber. It spreads very easily and mixes smoothly with resins and plastics, so it’s great for injection molding and coating applications. Because the fibers are so fine, it gives a more even, general reinforcement rather than strong, localized strength. It’s mainly used when good flow and easy processing matter more than maximum strength.
6mm is the most common type of chopped carbon fiber because it offers the best balance between strength and ease of processing. It disperses well in most materials and provides a solid boost in mechanical performance without causing processing issues. That’s why it’s widely used in automotive parts, engineering plastics, and general composite applications.
9mm chopped carbon fiber provides stronger reinforcement and better stiffness compared to shorter lengths. However, it’s a bit harder to disperse evenly, so it requires better processing control. It’s typically used in high-performance structural parts where maximum strength and rigidity are more important than ease of mixing.
Strength & Lightweight
Our chopped carbon fibers offer an exceptional strength-to-weight ratio, enabling you to create lighter and stronger products. This is especially important in automotive and aerospace applications, as weight reduction directly improves energy efficiency and performance while maintaining structural integrity.
