For What Is Chopped Carbon Fiber Used?
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.
Different applications require different fiber formats and load performance.
