Wuhan University of Textiles and Sanjiang China Aerospace Corporation have collaborated to develop a special national flag that was recently raised on the Moon by the lander of the Chang’e 6 mission. The flag is made from inorganic basalt fibers, which are known for their insulation and radiation resistance properties, making them ideal for space missions like this one.
The scholars and engineers faced challenges in weaving the yarn and ensuring the colors did not fade. The basalt fiber used for this flag has a higher density than that used for the Chang’e 5 flag, but the final product is lighter due to an ultra-thin basalt fiber developed by the researchers. This ultra-thin fiber has a diameter about one-third the size of a human hair.
The flag on the Chang’e 6 spacecraft measures about 30 cm x 20 cm, which is the same size as the one placed during the Chang’e 5 mission on the near side of the Moon. Basalt fibers are lightweight and flexible, making them suitable for use in various products such as spacesuits, spacecraft, lunar bases, protective clothing, and bags. Fireproof suits made from basalt fibers are cost-effective and can withstand high temperatures, making them valuable in firefighting and other applications.
This innovative material is expected to have a significant impact on the aerospace industry in the coming years as researchers continue to explore ways to apply basalt fibers in different products.
