carbon fiber ( #CarbonFiber) is a fiber-like material
Posted by JiangDavid on
boarbonFiber) is a fiber-like material with carbon as the main component (more than 90% carbon content, high performance grade often up to 95%). It is made from polyacrylonitrile, bituminous or viscose and other high temperature processes such as pre-oxidation and carbonization. It has both light weight, high strength, high modulus and corrosion resistance. It is not a natural form of single element carbon, but a artificially prepared fiber-shaped carbon material with mechanical properties far superior to traditional metals, often combined with resin to form a carbide composite. Here is the timeline for carbon fiber development:
1850 - British chemist Joseph Wilson Swann made carbon filaments from carbonized thin strips of paper, as a pre incandescent filament, opening the early exploration of carbon fiber.
1879 - American Edison improved the carbon wire preparation process, using carbonized natural fiber to make incandescent filament, and patented in 1892, laying the foundation for the early technology of carbon fiber.
1910 - The popularity of silk lamps, carbon filament was replaced, carbon fiber related research and development entered a long-term stagnation stage.
1950s—The Wright-Patterson Air Force Base, USA, prepared carbon fiber with viscose-based fiber, successfully applied to rocket nozzle, sinus and other burning aluminum components, restarted carbon fiber technology research and development; 1958 United Carbide Company realized the industrialization of viscose-based carbon fiber.
1959 - Japan Kondo invented the polyacrylonitrile (PAN-based) carbon fiber preparation process, greatly improving the strength of carbon fiber and opening the high-performance carbon fiber technology door.
1963 - The Royal Aeronautics Institute further enhanced the mechanical properties of carbon fiber by applying tension during the pre-oxidation phase; the same year, Japan's Okugani developed asphalt-based carbon fiber to expand the range of carbon fiber precursors.
1964—The United Kingdom and the United States achieved breakthrough in PAN-based high-mode carbon fiber and viscose-based high-strength carbon fiber technology, officially opening the era of high-performance carbon fiber.
1971: Japan's Toray Company built a mass production line of 12 tons of PAN-based carbon fiber, launched the first mass-production product Torayca (Torayca), leading the global carbon fiber industrialization.
1980s - High strength, high model, super high strength and other multi-series carbon fiber products came out one after another, and the application scene gradually expanded from aerospace to sports, leisure, automobile manufacturing and other civilian fields.
2001—China integrated carbon fiber technology research and development into the national " #863 plan", promoting domestic carbon fiber from technology research and development to industrialization.
2005—China successfully developed CF300 grade carbon fiber (the international T300 grade), achieving a breakthrough in domestic high-performance carbon fiber from scratch.
2021—China's carbon fiber production capacity surpasses the United States and Japan, becoming the largest country in the world's carbon fiber production capacity, and achieving a qualitative leap in industrialization scale.
2023-2025—China broke through the bottleneck of high-end carbon fiber technology, achieved mass production of T1000-class ultra-high-strength carbon fiber, and the price of the product dropped significantly, breaking the long-term technology and
In the future, it will continue to develop in the direction of high performance (higher strength, modulus and temperature resistance), low cost (large wire beam technology popularization), green (low energy consumption process and recycling technology), and further expand the civilian penetration rate in wind power, rail transportation and other fields.
