Characteristics, application and development of carbon fiber
2.Application of carbon fiber
Carbon fiber is a general term for fibers with a carbon content of more than 90%, and is named for its high carbon content. Carbon fiber has various excellent properties of elemental carbon, such as small specific gravity, heat resistance, thermal shock resistance, chemical resistance and conductivity, etc. It has fiber entanglement and excellent mechanical properties. In particular, its specific strength and specific elastic modulus are high, and it can withstand a high temperature of 2000 under the condition of isolating oxygen. It is an important industrial fibreglass raw material and is suitable for strengthening composite materials, ablation materials, and heat insulation materials. This is a new material developed in the early 1960s and has now become an indispensable new material in modern society.
Among leisure products, the first application of PAN carbon fiber is the fishing rod. At present, the world's annual output of carbon fiber fishing rods is about 12 million, and the amount of carbon fiber used is about 1,200 tons. The application of carbon fiber in golf clubs began in 1972. At present, the annual output of fibra de carbon golf clubs in the world is about 40 million bottles, and the amount of carbon fiber is equivalent to 2,000 tons. The application of tennis rackets started in 1974. Now, the world produced about 4.5 million carbon fiber rackets last year, and the use of carbon fiber requires about 500 tons. Among other things, carbon fiber is also widely used in skis, snow boats, ski sticks, baseball bats, road games, and marine sports.
Recognizing the lightweight, fatigue resistance, corrosion resistance and other properties of carbon fiber, it is widely used in the aerospace industry. In the field of space flight, high-modulus carbon fibers have been used in artificial satellites due to their light weight (rigidity) and thermal conductivity of dimensional stability. In recent years, they have been used in communication satellites such as iridium.
The molding compound is mainly mixed into the thermoplastic resin in the form of glass fibre chopped strands, which has the effect of strengthening, anti-static and electromagnetic wave shielding, and is widely used in home appliances, office equipment, semiconductors and related fields.
