[China Packaging News] "materials have the power to change society." Carbon fiber and carbon fiber reinforced plastics, which contribute to energy conservation and greenhouse gas reduction, are just like the slogan of Toray company in Japan. Toray holds about half of the world share of polyacrylonitrile carbon fibers. Toray's technical personnel engaged in development have long targeted cars, aircraft, atomic power generation, etc. Kyoto University in Japan, in conjunction with auto parts suppliers, has also developed a new lightweight and high-strength material extracted from wood pulp cellulose nanofibers, and developed cars and even aircraft made of carbon fibers. Subsequently, Toray started with sports and leisure products, and transformed the use of carbon fiber in cars, aircraft and wind turbines

Toray said that there are two things that can overturn the automotive industry or bring the automotive industry to a higher level in the future: one is artificial intelligence, the other is carbon fiber lightweight, and using carbon fiber composites to overturn metal materials

at present, Japan and the United States control most of the world's carbon fiber production capacity and control the production of high-end carbon fiber. Toray Corporation of Japan is the first to start the research and production of PAN based carbon fiber and is the representative of Japanese carbon fiber manufacturers. At present, the main producers of small tow carbon fiber in the world include Japan Toray, Japan Toho rayon and Japan Mitsubishi Rayon. Although the output of American companies is small, they can still compete with Japan's three giants in technology

before and after Dongli company developed carbon fiber, China then measured one or several mechanical properties and began to independently develop carbon fiber. Unfortunately, after nearly 40 years of development since the mid-1970s, the overall research and production level of China's carbon fiber industry is still very backward, unable to compete positively with American and Japanese companies in the market

it is estimated that under the same mileage, the weight of electric vehicles is more than 200~300 kg or more than that of traditional vehicles. Therefore, in order to ensure that the electric vehicle has a good range and affordable cost, the body weight of the electric vehicle must be reduced by more than 50%. Among all lightweight materials, carbon fiber is the only advanced material that can reduce the weight of steel parts by 50~60%, but can provide the same strength

carbon fiber reinforced complex metal fatigue is a common phenomenon. Composite materials have excellent physical properties: 30% lighter than aluminum, 50% lighter than steel, and 7 to 9 times the strength of steel. They were first used in high-tech fields such as aviation, aerospace, military industry and so on. It is generally acknowledged in the industry that CFRP (carbon fiber reinforced composite) is the best way to reduce the weight of new energy vehicles at present. The application of carbon fiber can reduce the weight of vehicles by 30% - 60%, which is known as the "king of lightweight". It is the leader of the "slimming revolution" of new energy vehicles and plays a key role in vehicle lightweight

looking at the current development of new energy vehicle industry, we can find that the wide application of carbon fiber composites in new energy vehicles is an inevitable result, and it is also an inevitable choice for new energy vehicle enterprises to produce and manufacture vehicles
