Superior Strength and Stiffness: The addition of carbon fibers dramatically improves PEEK's tensile strength, compressive strength, and rigidity, making it suitable for applications requiring exceptional load-bearing capacity.

High Thermal Resistance: Carbon fiber reinforced PEEK can withstand higher temperatures than unfilled PEEK, typically up to 300°C (572°F) for short periods. It also has a lower coefficient of thermal expansion, which means less deformation under heat.

Excellent Wear Resistance: This composite material offers superior wear and abrasion resistance, making it ideal for moving parts like gears, bearings, and seals.

Lightweight: Carbon fibers offer a high strength-to-weight ratio, allowing for lighter components without sacrificing strength, a critical factor in industries like aerospace and automotive.

Improved Conductivity: Carbon fiber enhances the electrical conductivity of the PEEK matrix, making this material suitable for applications where static dissipation or electrical conductivity is required.

Low Thermal Expansion: Carbon fiber reinforcement significantly reduces the thermal expansion of PEEK, providing dimensional stability even under high-temperature conditions.

Chemical and Corrosion Resistance: Like unfilled PEEK, carbon fiber reinforced PEEK maintains excellent resistance to most chemicals, including acids, alkalis, and solvents, making it suitable for chemically aggressive environments.
