Carbon fiber reinforced PEEK (polyetheretherketone) is a highperformance composite material that combines the excellent properties of PEEK with the high strength and high modulus of carbon fibers. It has broad application prospects.
Characteristics of Carbon Fiber Reinforced PEEK
1. Hih Strength and High Modulus:
The addition of carbon fibers significantly enhances the mechanical properties of PEEK, greatly increasing its tensile strength, flexural strength, and modulus. For example, PEEK reinforced with 30% carbon fibers can double its tensile trength at room temperature and even triple it at 150°C.
2. HighTemperature Resistance:
PEEK itself can be used longterm at 250°C, and when reinforced with carbon fibers, its heat deflection temperature can exceed 300°C, making it suitable for hightemperature environments.
3. Wear Resistance and SelfLubrication:
Carbon fiber reinforced PEEK exhibits excellent wear resistance and a low friction coefficient, making it suitable for harsh conditions such as nonlubricated, lowspeed, and highload applications. Its wear resistance even surpasses that of ultrahigh molecular weight polyethylene.
4. Lightweight:
Carbon fiber reinforced PEEK has a low density, significantly reducing component weight while maintaining high strength, making it ideal for lightweight design.
5. Chemical Corrosion Resistance:
PEEK itself has excellent chemical corrosion resistance, and the addition of carbon fibers further enhances its stability in corrosive environments.
6. Fatigue Resistance and Impact Resistance:
Carbon fiber reinforced PEEK performs exceptionally well under cyclic loading, with high fatigue resistance and impact energy absorption capacity (specific energy absorption up to 180 kJ/kg).
7. Ease of Processing and Repairability:
As a thermoplastic material, carbon fiber reinforced PEEK is easy to process and can be repaired through heating in case of minor damage, reducing maintenance costs.
Main Application Areas of Carbon Fiber Reinforced PEEK
Due to its lightweight, high strength, and hightemperature resistance, carbon fiber reinforced PEEK is widely used in aircraft and spacecraft structural components. For example:
The fairings of the Boeing 757200 series are made of carbon fiber reinforced PEEK.
The engine inspection covers of the F35 fighter jet use this material, known for its strong antidelamination properties and ease of repair.
The enginesurrounding fuselage skin and C130 belly panels of the Rafale fighter also utilize this material.

Carbon fiber reinforced PEEK excels in lightweight automotive design, replacing metal components to reduce energy consumption and improve performance. For example:
Bosch Group uses carbon fiber reinforced PEEK to replace metal in ABS functional components, reducing rotational inertia and enhancing system responsiveness.
Solvay's KetaSpire PEEK KT850 SCF 30 material is specifically designed for precision braking systems and electronic pump components in electric vehicles.
Carbon fiber reinforced PEEK is primarily used in drones for lightweight and highstrength requirements:
It is used to manufacture drone fuselage structures, propellers, and brackets, significantly reducing weight and improving flight stability.
4. Electronics and Electrical Industry:
Carbon fiber reinforced PEEK maintains excellent electrical insulation properties under high temperature, high pressure, and high humidity conditions, making it suitable for:
Vacuum suction cups, IC wafer carriers, and IC test sockets.
Carbon fiber reinforced PEEK has excellent biocompatibility and an elastic modulus close to that of human bones, making it suitable for:
Orthopedic implants, spinal fusion devices, and bone fixation plates.
Compared to traditional metal implants, it offers superior wear resistance and corrosion resistance.
6. Industrial Applications:
Carbon fiber reinforced PEEK is used to manufacture hightemperature and wearresistant industrial components, such as valve seats, sealing rings, and connectors.
