Applications of PI Materials in the Aerospace Field
It is suitable for components operating under extreme conditions in the aerospace, aviation, and missile industries, while meeting requirements for lightweight design, high-temperature resistance, electrical insulation, wear resistance, and corrosion protection.
- Aerospace structural components: aircraft‑mounted equipment brackets, aircraft fuel‑tank brackets, flexible hose clamps for aviation piping, helicopter gravity‑filling fuel tank caps, and radar radomes (withstanding low temperatures down to –168°C, long‑term exposure to high temperatures up to 250°C, radiation resistance, and salt‑spray corrosion resistance).
- High-Temperature Engine Components: high-temperature sleeves, heat shields, sealing rings, bearing cages, and wear‑resistant vibration‑damping parts for aeroengines (withstanding long-term operation at 450°C with high dimensional accuracy).
- Aerospace / Missile Components: missile tail cover (withstanding short-term temperatures of 600°C, providing thermal insulation and ablation resistance, and being electrically conductive), spacecraft thermal insulation film, rocket engine seals, and ablation‑resistant, flame‑retardant components located near the nozzle.
- Performance advantages: With a density only half that of aluminum alloy, it delivers significant weight reduction; oil‑resistant and corrosion‑proof without the need for surface coatings, it exhibits excellent fatigue resistance and corrosion durability, matching the service life of the airframe.
