Carbon fiber reinforced PEEK
Carbon fiber reinforced PEEK is a high-performance composite material made by combining PEEK (Polyether Ether Ketone) resin with carbon fibers. This reinforcement significantly enhances the mechanical, thermal, and electrical properties of the base PEEK polymer, making it one of the most robust materials used in critical engineering applications.

Key Properties of Carbon Fiber Reinforced PEEK:

  • 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.
