Carbon fiber is now the best T
First of all, carbon fiber is divided into T and M class two. T is the pursuit of strength, M grade is the pursuit of toughness (which is non-standard expression, in order to make everyone understand), a little professional, that is, M level is tensile strength. T class is now the highest level is T1000, M class, the highest level is MJ60., M class than T level more difficult to produce. T class, non professional, can be regarded as aviation level, widely used in aircraft, automobiles, high-level bicycles, etc.. Class M can also be considered space class or Japan as cosmic level. Used of rockets, spacecraft, satellites, etc.. (of course high-end M, such as MJ45, MJ60, etc., low end or inappropriate) Carbon brazing is finished by wire.
Raw material for resin, etc., do not elaborate here. The amount of silk contained in a thread is also a standard, 1K, 2K, 6K, 12K, etc. 1K=1000 silk. The smaller the more expensive. But the more expensive, the better. It depends on how small the T is. In principle, carbon fiber drawing is simple and difficult to carbonization. The temperature is out of control. The rate of finished products is now likely to be between 90% and 95% internationally. What follows is the focus. The world's most famous carbon fiber company is Japan's Dongli. Energy producing T1000 and MJ60. can also produce T800, of course. In fact, T800 prices are not high in the international market. T700 almost 17 USD/KG, T800 almost 35 USD/KG, because the production is large, low cost, so the Dongli T800 above the price of gross profit margin is basically around 20%.
