Carbon fiber is an essential strategic basis for cutting-edge weapons such as rockets, satellites, missiles, fighter jets and ships. The application of carbon fiber composite materials on the missile body and engine casing of the strategic missile can greatly reduce the weight and improve the range and assault capability of the missile. For example, the intercontinental missile three-stage shell developed in the 1980s in the United States is all made of carbon fiber and epoxy resin composite. material.

Carbon fiber composites are also being used in a large number of new generation fighters. For example, the US fourth-generation fighter F22 uses about 24% carbon fiber composite material, which makes the fighter super-sonic cruise, over-the-horizon combat, and high mobility. And stealth and other features. Boeing's Sonic Cruiser, a new generation of high-speed, wide-body passenger aircraft, will be made up of approximately 60% of its structural components, including reinforced carbon fiber composites, including wings.

China's self-developed carbon fiber composite brake prefabricated parts have reached international standards. The domestic carbon and carbon brake discs prepared by using this prefabricated technology have been mass-produced in military aircraft of key national defense models, and are used on the B757 civil aviation aircraft. The use on other models is also in the experimental assessment, and It will be promoted to tanks, high-speed trains, limousines, racing cars, etc.

Carbon fiber is lighter than aluminum but similar in strength. Carbon fiber also has important application value on ships. It can reduce the structural weight of ships and increase the payload of ships, thus improving the ability to transport combat materials. Carbon fiber does not have corrosion and rust. The use of carbon fiber materials can significantly reduce the structural weight, which can significantly improve fuel efficiency. Aircraft made of composite materials made of carbon fiber and plastic, as well as spacecraft such as satellites and rockets, have low noise, and because of their small mass and low power consumption, they can save a lot of fuel. According to reports, for every 1kg of the mass of the spacecraft, the launch vehicle can be reduced by 500 kilograms.
