Why choose carbon filled PEEK Sheet?

✅ Exceptional Wear Resistance & Self-Lubrication

Carbon fiber reinforcement enables the formation of a microscopic carbon transfer film on mating surfaces during friction. This inherent " self-lubricating" mechanism significantly reduces the coefficient of friction, extending component life in dynamic applications.

✅ High Load-Bearing Capacity & Minimal Deformation

The addition of carbon fiber elevates the flexural modulus from 4.2 GPa (neat PEEK) to 23 GPa. Under equivalent loads, CF-PEEK exhibits only 1/6th the deformation of unfilled PEEK. This superior rigidity ensures precision brackets and structural components maintain dimensional stability, effectively suppressing vibration and guaranteeing positioning accuracy.

✅ Long-Term Thermal Stability (260°C) & Dimensional Precision

Carbon fiber reinforced PEEK offers a high heat deflection temperature and a low coefficient of thermal expansion (CTE). The fiber matrix restricts resin expansion at elevated temperatures, ensuring minimal thermal deformation. This makes it ideal for high-temperature environments where consistent dimensional accuracy is critical.
