Carbon Fiber Chopped Strands 12mm 3mm (FORGED CARBON EFFECT)

short description:

Carbon fiber chopped strands are short, discrete lengths of carbon filament (typically ranging from 1.5 mm to 50 mm) that are cut from continuous carbon fiber tows. They are engineered to be used as a bulk reinforcement additive, dispersing the legendary strength and stiffness of carbon fiber throughout a base material to create advanced composite parts.

Introduction

Property

Isotropic Reinforcement: The random orientation of the strands provides balanced strength and stiffness in all directions within the molding plane, reducing the risk of splitting or directional weakness.

Exceptional Strength-to-Weight Ratio: They impart a significant increase in mechanical properties—tensile strength, stiffness, and impact resistance—while adding minimal weight.

Excellent Processability: Their free-flowing nature and short length make them perfectly suited for high-volume, automated manufacturing processes like injection molding and compression molding.

Design Flexibility: They can be incorporated into complex, thin-walled, and intricate geometric parts that are challenging with continuous fabrics.

Reduced Warpage: The random fiber orientation helps minimize differential shrinkage and warpage in molded parts, improving dimensional stability.

Surface Finish Improvement: When used in SMC/BMC or plastics, they can contribute to a superior surface finish compared to longer fibers or glass fibers.

Application

Reinforced Thermoplastics:

Injection Molding: Mixed with thermoplastic pellets (like Nylon, Polycarbonate, PPS) to create strong, stiff, and lightweight components. Common in automotive (brackets,housings), consumer electronics (laptop shells, drone arms), and industrial parts.

Reinforced Thermosets:

Sheet Molding Compound (SMC)/Bulk Molding Compound (BMC): A primary reinforcement for producing large, strong, and Class-A surface parts. Used in automotive body panels (hoods, roofs), electrical enclosures, and bathroom fixtures.

3D Printing (FFF): Added to thermoplastic filaments (e.g., PLA, PETG, Nylon) to significantly increase their strength, stiffness, and dimensional stability.

Specialty Applications:

Friction Materials: Added to brake pads and clutch facings to enhance thermal stability, reduce wear, and improve performance.

Thermally Conductive Composites: Used in combination with other fillers to manage heat in electronic devices.

Paints & Coatings: Used to create conductive, anti-static, or wear-resistant surface layers.
