Carbon fiber is a new material with excellent mechanical properties. Its proportion is less than 1/4 of the steel. The tensile strength of carbon fiber resin composite materials is generally above 3500MPa, which is 7-9 times steel, and the amount of anti -tensile elastic modulus is 23000. ~ 43000MPa is also higher than steel. Therefore, the ratio of the intensity of the CFRP, the intensity of the material, can reach 2000MPA/(G/CM3), while the ratio of A3 steel is only about 59MPa/(G/CM3), and its comparison is higher than the steel. The higher the material than the intensity, the smaller the component's self -weight, and the higher the amount of the mold, the greater the rigidity of the component. In this sense, the broad application prospect of carbon fiber in the project has been foreshadowed. Many people expect that polymer composite materials, metal base composite materials, and ceramic base composite materials) are expected that human beings are entering an era when materials are widely used from the steel age to a wide range of composite materials. , as the name suggests, it not only has the inherent characteristics of carbon materials, but also has the soft processability of textile fibers. It is a new generation of enhanced fiber. Compared with the traditional glass fiber (GF), Yang's modulus is more than three times; compared with the Kaffla Fiber (KF-49), it is not only about 2 times that of the Yang's modulus, but also in organic solvents, but also in organic solvents. , Involved in acid, alkali, and insolubleness, and emergence of corrosion resistance. Some scholars soaked PAN -based CF in a strong alkali NaOH solution in 1981. It has been more than 20 years since it has maintained a fiber form. The carbon fiber is an inorganic polymer fiber with a carbon content of less than 90 %. Among them, carbon -containing is called graphite fiber higher than 99 %. The axial intensity and modular amount of carbon fiber are high, no creep, good fatigue resistance, than thermal and conductive between non -metal and metal, small thermal expansion coefficient, good corrosion resistance, low density of fiber, X -ray transparent transparent transparency Good sex. However, its impact resistance is poor and easy to damage. Oxidation occurs under the action of strong acids. Metal carbonization, carburizing and electrochemical corrosion will occur when compounding with metal. Therefore, carbon fiber must be treated before use. The carbon fiber can be obtained with polypropylene fiber, asphalt fiber, adhesive fiber or phenolic fiber; according to the state, it is divided into long filament, short fiber and short -cut fiber; Performance. GM carbon fiber strength is 1,000 MPa (MPA) and the modular amount is about 100GPa. High -performance carbon fiber is divided into high -strength (strength 2000MPa, modulus 250GPa) and high models (more than 300GPa). The intensity is more than 4000MPa, also called ultra -high -strength type; the modulus is more than 450GPa called ultra -high models. With the development of the aerospace and aviation industry, high -strength and high -extension carbon fiber also appeared, with an extension rate of greater than 2 %. The most dosage is polypropylene Pan -based carbon fiber. The carbon fiber can be processed into fabrics, felt, seats, bands, paper and other materials. Except for the use of thermal insulation materials for carbon fiber, it is generally not used alone. It is mostly used as enhanced materials and adds to the resin, metal, ceramic, concrete and other materials to form composite materials. Reinforced composite materials for carbon fiber can be used as aircraft structure materials, electromagnetic shielding removal materials, artificial ligaments and other body materials, as well as to make rocket shells, motor ships, industrial robots, automotive plate springs, and drive shafts. The carbon fiber is a new material for military and civilians, which is a key material for technical dense and political sensitivity. 50s should be used in cutting -edge sciences such as rockets, astronal, and aviation. By the 1980s, they were widely used in sports equipment, textiles, chemical machinery and medical fields. At the same time, with the successive emergence of high -performance and ultra -high -performance carbon fiber, the scope of its application is getting wider and wider, such as A380, Boeing 777, and new American main battle tanks, and the proportion of carbon fiber accounts for more than 15%. At the same time, with the popularity of carbon fiber processing technology, its application scope has gradually involved civilian aspects since the 1980s. So far, various applications in my country account for 30%of sports in the demand for carbon fiber rates, 10%of aviation, and 60%of the industry.
This carbon fiber is mainly used in golf sticks, tennis rackets, racing, bow and arrows, jumping rods, yachts, rowing machines, manpower planes, sailing masts, motorcycles and mountaineering supplies, such as Mountaineering sticks, ski sticks, rock climbing helmets, etc.
