What is “Carbon Fiber Composite Material”? ( II )
Carbon fiber was born in the early 50s with the needs of advanced science and technology such as rocket, aerospace and aviation. Now it is also widely used in sports equipment, textile, chemical machinery and medicine. As the demands of advanced technology on the technical performance of new materials are becoming more and more demanding, the scientists and technicians have been making great efforts to improve it. In the early 80s, high performance and ultra-high performance carbon fibers appeared successively, which is another leap in technology. At the same time, it also indicates that the research and production of carbon fiber has entered an advanced stage.
The composite made of carbon fiber and epoxy resin has become an advanced aeronautical and astronautical material because of its small specific gravity, good rigidity and high strength. Because the weight of the spacecraft is reduced by 1 kilos per kilogram, the launch vehicle can be reduced by 500 kilograms. Therefore, advanced composite materials are competing in the aerospace industry. There is a vertical landing fighter, which uses carbon fiber composites to account for 1/4 of the total weight of the aircraft, accounting for 1/3 of the wing weight. It is reported that the key components of the 3 rocket propellers on the US space shuttle and the advanced MX missile launchers are made of advanced carbon fiber composites.
