Carbon Fiber Powder
Ground carbon fiber powder (milled carbon fiber) for use as high-performance composite filler. Retains excellent properties of carbon fiber in powder form.
Key Features
- Large specific surface area
- Easy resin wetting
- Reinforcement filler
- Thermal and electrical conductivity
Overview
Carbon fiber powder, also known as milled carbon fiber, is produced by grinding carbon fiber into a fine black-gray powder while retaining the material's reinforcing, conductive, and wear-resistant properties. The large specific surface area of the powder allows it to wet out easily in resin, distributing carbon's benefits evenly throughout a matrix as a high-performance filler.
Compounded into thermoplastic and thermoset resins, the powder reinforces the matrix, raises electrical and thermal conductivity, and improves wear resistance and dimensional stability. Because it is a fine particulate rather than a fiber bundle, it can be loaded at high concentrations and used in injection molding, casting, and coating formulations where fibrous reinforcement would be impractical.
Carbon fiber powder is a versatile additive for applications that need carbon's functional properties in a flowable, easily dispersed form, from conductive plastics to wear-resistant components and friction materials.

Frequently Asked Questions
What is carbon fiber powder used for?
It serves as a high-performance filler in thermoplastic and thermoset resins, adding reinforcement, electrical and thermal conductivity, and wear resistance in a form that disperses easily and can be loaded at high concentrations.
How is carbon powder different from short cut fiber?
Carbon powder is milled into fine particles, so it flows and disperses like a filler and suits injection molding, casting, and coatings. Short cut fiber retains a fibrous form that provides more directional reinforcement.
Why does the large surface area matter?
The large specific surface area lets the powder wet out readily in resin, ensuring even distribution of its reinforcing and conductive properties throughout the matrix.
