The conductivity and thermal conductivity of carbon fiber powder far exceed traditional metal materials. Its conductivity is as high as 10 ⁴ S/m, making it widely applicable in electronic components, conductive coatings, and anti-static materials. At the same time, the thermal conductivity of carbon fiber powder is as high as 1000 W/m · K, which can effectively improve the material's heat dissipation performance and is an ideal choice for high thermal conductivity materials.

Although the particles of carbon fiber powder are small, it inherits the high strength and lightweight characteristics of carbon fiber itself. Its typical tensile strength exceeds 4 GPa and its density is only 1.75 g/cm ³. This enables carbon fiber powder to significantly improve the strength and rigidity of composite materials when used as a reinforcing agent, while maintaining lightweight, making it particularly suitable for applications that require high strength and low weight.

Carbon fiber powder has excellent high temperature resistance and can remain stable at temperatures up to 3000 degree C without melting or degradation. In addition, the chemical inertness of carbon fiber makes it highly corrosion-resistant to most acids, bases, and organic solvents. This makes carbon fiber powder exhibit significant advantages in applications in high-temperature and corrosive environments, such as high-temperature filtration materials, corrosion-resistant coatings, etc.

Carbon fiber powder undergoes strict grading and screening processes, resulting in uniform particle size. The typical particle diameter range is 5-50 microns, and the specific surface area can reach 50 m ²/g. This high specific surface area powder material can form a uniform dispersed structure in composite materials, significantly improving the interfacial and overall mechanical properties of the material, while also having excellent effects in conductivity, heat conduction, adsorption, and other aspects.

Carbon fiber powder is widely used to enhance the mechanical properties of composite materials, especially in resin based composites and ceramic based composites. The composite material with added carbon fiber powder has significantly improved bending strength, compression strength, and impact toughness. Experimental data shows that when the amount of carbon fiber powder added is 5% -10%, the bending strength of the composite material can be increased by 25% -40%, the compressive strength can be increased by 30% -50%, and it has better fatigue resistance.
