Carbon fiber-filled PEEK is a composite material that combines the high-performance plastic PEEK with carbon fibers to enhance its mechanical, thermal, and electrical properties. This combination results in a modified PEEK that is much stronger, stiffer, and lighter than standard unfilled PEEK grades.

Carbon fiber-filled PEEK is reinforced with short or long carbon fibers, typically in concentrations between 10% to 30% by weight, with 30% being the most common and widely used. The fibers are distributed throughout the PEEK matrix which greatly enhances its mechanical properties.

Compared to unfilled peek, carbon fiber-filled PEEK has several enhanced properties.

• Increased Strength and Stiffness
• Improved Dimensional Stability
• Superior Thermal Properties
• Enhanced Wear Resistance
• Lower Weight and High Strength-to-Weight Ratio
• Improved Chemical And Corrosion Resistance

Common applications include:

• Oil & Gas: seals, valves, washers
• Medical Devices
• Electronics
• Aerospace: Various structural components
