Commercial aerospace equipment must withstand intense launch loads, extreme temperature variations in space (-270°C to 120°C), and high radiation levels. Carbon fiber materials meet the core requirements of satellites, rockets, and spacecraft through “structural lightweighting + performance customization.” Satellite main structures: Core components including satellite load-bearing cylinders, solar array supports, and antenna reflectors; Spacecraft structural components: Key elements for weight reduction and stability, primarily applied to spacecraft hulls and components.
