The main purpose of carbon fiber is to compound with resin, metal, ceramic and other substrates to make structural materials. Carbon fiber reinforced epoxy resin composite material has the highest comprehensive index of specific strength and specific modulus among the existing structural materials. In areas with strict requirements on density, stiffness, weight, fatigue characteristics, etc., where high temperatures and high chemical stability are required, carbon fiber composites have advantages.Introduction Of The Use Of Carbon Fiber
Carbon fiber was produced in the early 1950s in response to the needs of cutting-edge science and technology such as rockets, aerospace and aviation. It is also widely used in sports equipment, textiles, chemical machinery and medicine. With the increasingly stringent requirements of cutting-edge technology for the performance of new materials, scientific and technological workers are constantly striving to improve. In the early 1980s, high-performance and ultra-high-performance carbon fibers appeared one after another, which was another leap in technology, and also marked the advanced stage of carbon fiber research and production.Introduction Of The Use Of Carbon Fiber
The composite material composed of carbon fiber and epoxy resin is an advanced aerospace material because of its small specific gravity, good rigidity and high strength. Because for every 1 kg of weight loss of the spacecraft, the launch vehicle can be reduced by 500 kg. Therefore, in the aerospace industry, competing for the use of advanced composite materials. There is a vertical take-off and landing fighter, which uses carbon fiber composite material has accounted for 1/4 of the weight of the entire aircraft, 1/3 of the weight of the wing. According to reports, the key components of the three rocket thrusters on the US space shuttle and advanced MX missile launch tubes are made of advanced carbon fiber composite materials.
F1 (World Formula One Championship) racing car, most of the car body structure uses carbon fiber material. A major selling point of top sports cars is the use of carbon fiber throughout the body to improve aerodynamics and structural strength
Carbon fiber can be processed into fabric, felt, mat, belt, paper and other materials. In the traditional use, carbon fiber is generally not used alone except for thermal insulation materials. It is often added as a reinforcement material to resin, metal, ceramic, concrete and other materials to form a composite material. Carbon fiber-reinforced composite materials can be used as substitute materials for aircraft structures, electromagnetic shielding and static elimination materials, artificial ligaments and other body substitute materials, as well as for manufacturing rocket shells, motor boats, industrial robots, automobile leaf springs and drive shafts.
