Carbon fiber composite material used in automobile and aviation industry carbon fiber is the main use of resin, metal, ceramics and other matrix composite, made of structural materials. Carbon fiber reinforced epoxy resin composite material, its specific strength, ratio of the composite index, in the existing structure of the material is the highest. In the density, stiffness, weight, fatigue characteristics, such as the strict requirements of the field, in the requirements of high temperature, high chemical stability, carbon fiber composite materials are quite advantage.
Carbon fiber is in the early 50's should be rocket, aerospace and aviation and other cutting-edge science and technology needs, and now also widely used in sports equipment, textile, chemical machinery and medical fields. With the increasing demand for the technology of the new materials, the advanced technology has prompted the scientific and technical workers to make efforts to improve the performance of the new materials. In the early 80's, high performance and ultra high performance carbon fibers have emerged, which is another leap in technology, but also marks the research and production of carbon fiber has entered a senior stage.
Composite material made of carbon fiber and epoxy resin, because of its low specific gravity, high rigidity and high strength, it has become a kind of advanced aerospace materials. Because the weight of the space vehicle is reduced by 1 kg, it will reduce the weight of the rocket by 500 kg. So, in the aerospace industry competing for the use of advanced composite materials. There is a vertical landing aircraft, which uses the carbon fiber composite material has been accounted for the entire weight of 1/4, accounting for the weight of the wing 1/3. According to reports, the U.S. space shuttle on 3 key components of the rocket propulsion and advanced MX missile launch tube, etc., are made of advanced carbon fiber composite materials.
F1 (the world's first stage equation) racing car, most of the structure of the body with carbon fiber material. Top sports car, a big selling point is about the use of carbon fiber, in order to improve the aerodynamic and structural strength.
Carbon fiber can be processed into fabric, felt, mat, tape, paper and other materials. Traditional use of carbon fiber in addition to use as an insulation material, the general does not use alone, and more as a reinforcement to add to the resin, metal, ceramic, concrete and other materials, constitute a composite material. Carbon fiber reinforced composite materials can be used as aircraft structural materials, electromagnetic shielding in electrical materials, artificial ligaments and other body substitute materials as well as for manufacturing the rocket shell, motor boats, industrial robots, automobile plate spring and drive shaft etc.
