Carbon fiber is an important hallmark of aerospace competitiveness
China has become the third country in the world that has its own satellite navigation system, and carbon fiber is indispensable in this regard. The Beidou satellite looks like a house with two wings, and its house and wings are made of carbon fiber composite materials. Why carbon fiber? First of all, the satellite needs to be equipped with enough instruments and equipment, and its structure-to-weight ratio is required to be less than 5%, so carbon fiber must be used; secondly, satellite antennas, cameras and other equipment require high precision, and to solve the problem of thermal deformation, carbon fiber It just has this advantage, so now high-performance satellites including Beidou satellites are made of carbon fiber composite materials.
