Aluminum-based silicon carbide fuels the space dream

With the final countdown, the booming "Shenzhou XIV" was perfectly launched at the Jiuquan Satellite Launch Center at 10:44 on June 5, 2022, this liftoff is the second flight in the construction phase of the Chinese space station, and it is also the first manned mission in this phase, "Tianzhou 4" has sent oxygen, water, food, and other daily necessities into space early, and astronauts are expected to work and live on the space station for 6 months.

People's continuous exploration of the universe, the demand for launch vehicles is also increasing. For example, before the launch of the "Shenzhou XIV", it had actually been preparing for the Jiuquan Satellite Launch Center for 8 months. The new model of aerospace currently developed is "launch one shot, backup one shot" Even if manned spaceflight has countless successful cases, it will prepare backup spacecraft in advance, just in case.

Among today's launch vehicle structural materials, aluminum and aluminum matrix composites are the most used types of materials. It is estimated that among the launch vehicle structures and components, the net mass of aluminum and aluminum alloys accounts for more than 85% of the total net mass of the structure. Aluminum alloy density is small (≤2.8g / cm3), specific strength and specific stiffness, corrosion resistance, fatigue resistance, good toughness, excellent processing and molding performance, the new composite material aluminum-based silicon carbide in maintaining the original advantages of aluminum alloy at the same time, has 3 times higher than the aluminum alloy specific stiffness and elastic modulus. Aluminum alloys are already indispensable materials for aerospace, and aluminum-based silicon carbide has become an ideal material to replace other alloys in terms of improving accuracy and product performance.

Entering the opening year of the "Fourteenth Five-Year Plan", Henan Hanyin Optoelectronic Technology Co., Ltd. and 2021 give full play to the advantages of scientific and technological innovation, after years of scientific research, increase the technological transformation of existing production equipment, successively break through the traditional composite materials in low density, large heat resistance between particles, poor connectivity of aluminum alloys, harmful interface products and other technical bottlenecks, the formation of China's independent intellectual property rights, affixed with "Chinese label" innovative new technologies, and achieved industrialization, performance reached the international advanced level. Henan Hanyin Optoelectronics adheres to the development of China's aerospace industry, continuously develops and produces in order to serve the national strategy, and makes unremitting efforts for China's aluminum alloy application to move towards the end of the industrial chain and the high-end of the value chain.
