carbon fiber reinforced PEEK sheets

Carbon Fiber Reinforced PEEK Sheets for Demanding Applications

When engineering components must deliver exceptional stiffness, low weight, and reliable performance in harsh environments, carbon fiber reinforced PEEK sheets become the material of choice. Our advanced portfolio includes PEEK CA30 sheets with 30% carbon fiber loading, precision-manufactured carbon fiber Filled PEEK plate options, and high-spec PEEK CF30 plate configurations. Each variant is engineered to bring the remarkable thermal stability, chemical resistance, and mechanical strength of PEEK to aerospace, medical, semiconductor, and oil & gas industries. The carbon fiber reinforcement drastically improves modulus and creep resistance while retaining the inherent flame retardancy and sterilization capability of the base polymer. Whether machined into valve seats, seals, structural brackets, or surgical instrument handles, these sheets deliver consistent quality with tight thickness tolerances and an ultra-smooth surface finish that minimizes secondary processing. Certified lot traceability and available in industry-standard dimensions make these products ideal for both prototype runs and high-volume production schedules.

Every batch of carbon fiber reinforced PEEK sheets is produced under strict process control to guarantee uniform fiber dispersion and void-free consolidation. The material exhibits a continuous service temperature of 250°C, outstanding wear resistance, and a coefficient of thermal expansion that closely matches aluminum, reducing stress in multi-material assemblies. Customers rely on carbon fiber reinforced PEEK sheets for ultra-high-vacuum seals, high-load bearing rings, and blood-contact components that require repeated autoclaving. The sheets can be machined, drilled, and tapped with standard carbide tooling, and their low moisture absorption preserves dimensional stability in wet or chemically aggressive conditions. Below you’ll find detailed technical data that highlights the difference between our standard grades, helping engineers select the exact configuration for their load case and environment.
