'Materials have the power to change society.' As with the slogan of Toray in Japan, carbon fiber and carbon fiber reinforced plastics that contribute to energy conservation and greenhouse gas reduction. Toray holds about half of the world's share of polyacrylonitrile carbon fiber. Toray's development technicians have long been targeting cars, airplanes, and atomic power generation to develop carbon fiber cars and even airplanes. Later, Toray began with sports and leisure goods, and at the same time, cars and aircraft. 4. Wind turbines have been modified for use of carbon fiber.
Toray said: There are two things that can subvert the automotive industry or bring the automotive industry to a higher level in the future: one is artificial intelligence, the second is carbon fiber lightweight, using carbon fiber composites to subvert metal materials.
At present, Japan and the United States hold most of the world's carbon fiber production capacity and control the production of high-end carbon fiber. Japan Toray Corporation started out in the development and production of PAN-based carbon fiber, and is the representative of Japanese carbon fiber production enterprises. Currently the world's small tow The main producers of carbon fiber include Japan Toray, Japan Toho rayon, and Japan Mitsubishi Rayon. Although the US company has a small output, it is technically comparable to the Japanese Big Three.
Before and after the development of carbon fiber by Toray, China began to independently develop carbon fiber. But unfortunately, after nearly 40 years of development in the mid-1970s, the overall development and production level of China's carbon fiber industry is still very backward, unable to be beautiful. Japanese company competes positively in the market.
According to estimates, under the same cruising range, the weight of electric vehicles is more than 200~300 kg or more than that of traditional cars. Therefore, in order to ensure that electric vehicles have better cruising range and affordable cost, the weight of electric vehicles must be reduced. It weighs 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 composites have excellent physical properties: 30% lighter than aluminum, 50% lighter than steel, and 7 to 9 times stronger than steel. It was first used in the high-tech fields of aviation, aerospace, military and other industries. CFRP (carbon fiber reinforced composite material) is currently the best way to solve the weight loss of new energy vehicles. The application of carbon fiber can make the vehicle lose weight by 30%~60%. It is known as the 'king of light weight' and is a new energy vehicle' The leader of the slimming revolution has played a key role in car lightweighting.
Looking at the current development of the new energy automobile industry, it can be found that the wide application of carbon fiber composite materials in new energy vehicles is an inevitable result, and it is also an inevitable choice for new energy automobile enterprises to carry out automobile production and manufacturing.
