1.Structural components
- Wing and fuselage structural parts: The wings and fuselage of an aircraft require materials with high strength and light weight. JSM-PI polyimide profiles can reduce the weight of the aircraft while ensuring structural strength. They can be used to manufacture wing ribs, stringers, and fuselage frames, skins and other components, which help improve fuel efficiency, increase range and payload5.
- Spacecraft frame: In spacecraft, polyimide profiles can be used to build the main frame of the spacecraft. Its high strength and good fatigue resistance can withstand the huge impact force during launch and various mechanical loads in the space environment, ensuring that the spacecraft maintains structural stability in the complex space environment.
2.Thermal protection system
- Engine insulation components: Aircraft engines will generate extremely high temperatures during operation. JSM-PI polyimide profiles can be made into engine heat shields, heat shields, etc. Its low thermal conductivity and high heat resistance can effectively block heat transfer, protect the structures and equipment around the engine from high temperatures, and improve the reliability and service life of the engine28.
- Spacecraft thermal control materials: When a spacecraft reenters the atmosphere, it will face extremely high temperatures. Polyimide profiles can be used as part of the thermal protection system to protect the equipment and personnel inside the spacecraft through its excellent thermal insulation performance and high-temperature stability. It can also be used to manufacture thermal control coatings and thermal insulation pads for spacecraft, adjust the temperature distribution on the surface of the spacecraft, and ensure that the internal instruments work within the appropriate temperature range.
3.Electrical system
- Printed circuit boards: Polyimide profiles can be made into high-performance printed circuit boards for use in aerospace electronic equipment. Its good electrical properties, dimensional stability and high temperature resistance can meet the requirements of aerospace electronic systems for miniaturization, high reliability and high performance of circuit boards, and ensure the stable operation of electronic equipment.
4.Other components
- Sealing components: Reliable sealing components are required in hydraulic systems, fuel systems, etc. in aerospace. JSM-PI polyimide profiles have good oil resistance, chemical corrosion resistance and elasticity, and can be used to manufacture sealing rings, sealing pads, etc. to ensure the sealing and reliability of the system and prevent liquid and gas leakage.
- Bearing and gear components: The high strength, low friction coefficient and wear resistance of polyimide profiles make them suitable for manufacturing bearing retainers, gears and other transmission components in aerospace equipment. They can reduce friction loss, improve transmission efficiency, reduce noise and vibration, and extend the service life of components.
