High Temperature High Load Stability PEEK CF30

PEEK (Polyether Ether Ketone) is a high-performance specialty engineering plastic. The addition of carbon fiber (CF) significantly enhances its mechanical properties, dimensional stability, and wear resistance. The primary difference between PEEK CF20 and PEEK CF30 lies in the carbon fiber content (20% and 30%, respectively), which directly impacts the material properties and applicable scenarios.

PEEK CF30 typically exhibits 10%-25% higher tensile strength and bending strength compared to CF20, offering greater load-bearing capacity. Its bending modulus (stiffness) is approximately 20%-30% higher than that of CF20, providing optimal resistance to deformation. The higher carbon fiber content offers better self-lubricating properties and wear resistance, with a lower friction coefficient. PEEK CF30 also has a lower coefficient of thermal expansion, resulting in minimal dimensional changes with temperature fluctuations and higher precision. Under long-term load, CF30 demonstrates superior shape retention. In high-load conditions, CF30 has enhanced resistance to high-temperature deformation.

Typical Applications of PEEK CF30
PEEK CF30 is suitable for harsh environments requiring extreme rigidity, dimensional stability, wear resistance, and high-temperature load-bearing capacity.
• Aerospace & Defense: Primary load-bearing structures, missile components, drone body frames, high-temperature components around engines (maximizing weight reduction while ensuring rigidity).
• High-Performance Automotive: F1 racing gearbox gears, high-performance engine piston rings, connecting rod bushings (designed to withstand extreme mechanical loads and temperatures).
• Oil & Gas: Downhole exploration tool components, valve seats, sealing rings (requiring high pressure resistance, wear resistance, and long-term dimensional stability).
• High-End Industrial: Precision measuring instrument frames, high-strength robotic joints, high-load synchronous pulleys (eliminating even the smallest deformation).
• Competitive Sports Equipment: Top-tier bicycle frames, competition ski binding (pursuing the ultimate stiffness-to-weight ratio).

Choose PEEK CF30:
When your design faces extreme mechanical loads, demands rigorous stiffness, or requires absolute dimensional accuracy under high temperatures, PEEK CF30 is the ideal choice. It is commonly used to replace metals or ceramics to achieve weight reduction and avoid issues such as corrosion.
