PEEK Material in Aerospace Applications‌
Leveraging its high-temperature resistance, lightweight properties, and corrosion resilience, PEEK (Polyether Ether Ketone) is widely adopted in aerospace for the following five categories of critical components:

Combining the multiple performance advantages, PEEK has considered as the high performance engineering plastic‌ in aerospace, effectively replacing conventional metals.

‌I. Structural Components‌

· ‌Primary spacecraft structures‌: Airframe frameworks, cabin skins, wing components, etc., achieving lightweight design by replacing traditional metals.

· ‌Solar panel brackets‌: High strength and radiation resistance ensure stability in harsh space environments.

‌II. Power System Components‌

· ‌Engine components‌: Valves, piston rings, oil pump rotors, and other core parts operating under high-temperature/pressure conditions, ensuring reliability in extreme environments.

· ‌Turbocharger impellers‌: Withstand high-speed rotation and elevated temperatures to enhance engine efficiency.

‌III. Thermal Protection & Sealing Systems‌

· ‌Thermal control components‌: Used in spacecraft thermal shielding to withstand high-temperature impacts during atmospheric re-entry.

· ‌Seals and bearings‌: Maintain sealing integrity and wear resistance in vacuum and extreme thermal cycling conditions.

‌IV. Electrical & Electronic Systems‌

· ‌Cable trays and insulation layers‌: Flame-retardant and heat-resistant electrical insulation materials ensure circuit safety.

· ‌Electronic enclosures‌: Housings for navigation systems and communication devices meet flame-retardant standards while ensuring signal stability.

‌V. Auxiliary Functional Components‌

· ‌Cabin interiors‌: Lightweight yet high-strength cabin components such as seats, handles, and tables.

· ‌Fuel systems‌: Corrosion-resistant parts like fuel filters and pump housings, compatible with complex chemical environments.
