Chopped Carbon Fiber
If you are looking for a lightweight yet high-strength filler or reinforcement material, chopped carbon fiber strands offer an excellent solution. These short carbon fibers are widely used in compression and injection molding, where they improve part performance, durability, and even electrical properties. From industrial machine parts to consumer products, chopped carbon fiber delivers targeted strength—without compromising formability or efficiency.
For What Is Chopped Carbon Fiber Used?
Chopped carbon fiber strands are commonly used in compression and injection molding processes to create high-performance parts. These parts—often referred to as forged carbon fiber composites—are ideal for demanding applications in sectors such as:
- Automotive (gears, covers, brackets)
- Bicycle and sporting equipment
- Industrial machinery parts
- Consumer electronics and appliance housing
Due to their short, free-flowing form, chopped fibers easily conform to intricate geometries and detailed features during molding. Additionally, they are suitable for DMC (Dough Molding Compound) and BMC (Bulk Molding Compound) formulations, either as a main reinforcement or as an additive to enhance strength and stiffness.
For customers seeking hybrid properties, a carbon and fiberglass mix (70/30) is also available—balancing stiffness and cost-efficiency.
Key Properties and Performance Advantages
The properties of chopped carbon fiber make them ideal for a variety of structural and functional roles:
• Excellent corrosion resistance
• Creep and fatigue resistance
• Rigid and durable
• High formability
• Anti-static behavior
• Gap filler
• Multi-resin compatibility
• Aesthetic surface quality
Even in small volumes, chopped fibers significantly enhance part performance—boosting strength, conductivity, and structural reliability.
