Chopped Carbon Fiber Flake is a versatile additive made by cutting continuous carbon fibers into small, flake-like pieces. Unlike unidirectional fibers, it distributes evenly in matrices, boosting overall material performance without directional bias. Easy to blend with thermoplastics or thermosets, it lowers production costs while adding structural reinforcement, widely used in automotive parts, electronics, and consumer goods.

Feature：

Isotropic reinforcement：

Random dispersion provides uniform strength in all directions, unlike directional fiber materials.

Cost-efficiency：

Lower production and processing costs compared to continuous or unidirectional carbon fibers.

Easy integration：

Compatible with various matrices (resins, polymers) and adaptable to molding, extrusion, or injection processes.

Application：

Automotive components：

Used in plastic parts like bumpers and interior panels to enhance impact resistance and reduce weight.

Electrical enclosures：

Incorporated into casings for electronics to improve thermal conductivity and structural rigidity.

Sporting goods：

Added to items like helmet shells and kayak hulls for balanced strength and durability.
