The composite material composed of carbon fiber and epoxy resin has become an advanced aerospace material due to its small specific gravity, good rigidity and high strength. Because the weight of the spacecraft is reduced by 1 kilogram, the launch vehicle can be reduced by 500 kilograms. Therefore, in the aerospace industry, there is a rush to adopt advanced composite materials.
There is a vertical take-off and landing fighter, which uses carbon fiber composite materials that account for 1/4 of the weight of the aircraft and 1/3 of the weight of the wings. According to reports, the key components of the three rocket thrusters on the US space shuttle and the advanced MX missile launch tube are all made of advanced carbon fiber composite materials.
