Carbon fiber rod Application Practice of GPS in Spacecraft Structure
Carbon fiber rod is a kind of high-performance reinforcement material, which has been widely used in spacecraft structures due to its high strength, high stiffness and light weight. In this paper, the characteristics of carbon fiber rod and its application in spacecraft structure are introduced in detail.
1、 Characteristics of carbon fiber rod
Carbon fiber bar is a kind of reinforced material made of carbon fiber reinforced resin or other matrix materials, which has the following characteristics: ① high strength: the strength of carbon fiber bar is 5~10 times higher than that of steel, and 2~5 times higher than that of aluminum; ② High rigidity: the rigidity of carbon fiber bar is 6 times higher than that of steel with the same weight; ③ Lightweight: the density of carbon fiber bar is only 1/4 of steel and 1/3 of aluminum; ④ Corrosion resistance: carbon fiber rod is not easy to be corroded by chemicals and has good corrosion resistance; ⑤ Good electrical insulation: the electrical insulation of carbon fiber rod is better than that of metal.
2、 Application of carbon fiber rod in spacecraft structure
Reinforcements
The high strength, high rigidity and light weight of carbon fiber bar make it an ideal reinforcement material. In spacecraft structure, carbon fiber rods are often used to strengthen some key parts, such as rudder, fuselage, etc.
Lightweight structural members
The light weight of carbon fiber rod makes it an ideal structural material. In spacecraft structures, carbon fiber rods are often used to make lightweight structural parts, such as support beams, rubber bands, etc.
Thermal control materials
The thermal conductivity of carbon fiber rod is very poor, which can play a role in the thermal control of spacecraft to a certain extent. In spacecraft structures, carbon fiber rods are often used to make thermal control materials, such as heat cancer, heat shield, etc.
Electrical insulating materials
Carbon fiber rods have good electrical insulation properties, and are often used as electrical insulation materials in spacecraft structures, such as cable trays, cable supports, etc.
With the continuous development of carbon fiber rods in the field of materials science and technology, their applications in spacecraft structures are also increasingly extensive. In the future, carbon fiber rods will become an indispensable material in spacecraft structures.
