The main purpose of carbon fiber is to combine with resin, metal, ceramic and other matrix to make structural material. Carbon fiber reinforced epoxy resin composite material, its ratio strength, than the modulus comprehensive index, in the existing structure material is the highest. In the field of density, stiffness, weight and fatigue characteristics, carbon fiber composite materials have advantages in high temperature and chemical stability.

Carbon fiber was produced in the early 1950s by the needs of advanced science and technology such as rocket, aerospace and aviation, and is now widely used in sports equipment, textile, chemical machinery and medicine. With the increasingly stringent requirements on the technical performance of new materials, technology workers are constantly striving to improve. In the early 1980s, high performance and super high performance carbon fiber appeared, which was another leap in technology, and also marked the advanced stage of research and production of carbon fiber.

Composite materials made of carbon fiber and epoxy resin have become advanced aerospace materials due to their small proportion, high rigidity and high strength. For every kilogram of space shuttle lost, the launch vehicle could be reduced by 500 kilograms. Therefore, advanced composite materials are used in the aerospace industry. There is a vertical take-off and landing fighter, and its carbon fiber composite material already accounts for 1/4 of the weight of the aircraft, 1/3 of the weight of the wing. It is reported that the key components of the three rocket boosters on the us space shuttle and the advanced MX missile tubes are all made of advanced carbon fiber composite materials.

Today's formula one racing car, most of its structure is made of carbon fiber. One of the big selling points of top sports cars is the use of carbon fibre, which improves aerodynamic and structural strength.

Carbon fiber can be processed into fabric, felt, mat, tape, paper and other materials. In the traditional use of carbon fiber in addition to the used as insulation materials, is generally not used alone, much as reinforced material added to the resin, the material such as metals, ceramics, concrete, composite materials. Carbon fiber reinforced composite material can be used for aircraft structure materials, electromagnetic shielding in addition to the body, such as electric materials, artificial ligament substitute material and used in the manufacture of rocket shell, powerboat, industrial robots, automobile plate spring and the drive shaft, etc.
