The 15th China International Aviation and Aerospace Expo was held in Zhuhai. Unprecedented scientific and technological achievements such as "stealth fighter" have shocked the world, and China's dream-chasing power has amazed the world. But many people may not know that there is a lot of textile black technology hidden in these aerospace technologies!
Build new quality combat effectiveness with new quality productivity
When it comes to textiles, many people's first association is clothes and quilts, these daily items.
In fact, modern textiles can enter the ground and go to the sky, which has long gone beyond the daily application of clothing covers and has become a national basic industrial category covering all walks of life, and also plays a huge role in promoting the progress of aerospace.
What are the textile black technologies in the aerospace field? Let's find out
1. Stealth aircraft absorbing material
The J-20 and J-35A stealth fighters on display at the air show attracted the attention of military enthusiasts.
One of the key technologies for stealth aircraft to achieve "stealth" is the application of wave absorbing materials (RAM), which can effectively absorb part of the radar waves, converting them into heat or other forms of energy, thereby reducing the reflection of the radar waves.
The production process of the absorbing material is complex, and its composition mainly includes two parts: absorbent and absorbent carrier. Commonly used absorption carriers, such as carbon fiber, glass fiber and polyimide, rely on the exquisite process of modern textile technology.
The textile industry's deep accumulation in the optimization of mechanical properties and electrical conductivity of fibers, as well as coating technology and composite material production technology, has played a crucial role in improving the performance of wave absorbing materials.
2. Aircraft shell material
The shell of the aircraft is made of woven textile materials such as reinforced carbon fiber composite materials. These materials have the characteristics of light weight and high strength, which can effectively reduce the weight of the aircraft and improve the flight efficiency.
3. Parachute and flight suit
Specialty textiles are used to make parachutes and pilots' flight suits. These materials need to have high strength, light weight, wear resistance and specific aerodynamic properties to stabilize the attitude of the aircraft during high-speed descent, and slow down the descent speed to ensure a safe landing.
