Popular science: First, carbon fiber is divided into T-grade and M-grade. T-level pursuit of strength, M-level pursuit of toughness(Grade M is tensile strength). The highest level of T is now T1000, and the highest level of M is MJ60. M is more difficult to produce than T.
?
T-level non-professional people can be considered as aviation level, widely used in aircraft, cars, advanced bicycles and so on. The M-class can also be considered as a space class or a Japanese expression as a cosmic class. For rockets, spacecraft, satellites, etc.
(Of course, it is high-end M-class such as MJ45,MJ60, etc. The low-end is still inappropriate.) The carbon brazing dimension is finished in the form of wire. The raw material is resin, etc., which will not be described in detail here. contained in a strand of silk
The amount of silk splitting is also a standard. There are 1K 2K 6K 12K and so on 1K = 1000 silk respectively. The smaller the number, the more expensive. But not the more expensive the better. It also depends on the T level. In principle, carbon fiber drawing is simple
Carbonization is extremely difficult. Temperature control is not good on the waste. The current yield may be between 90% and 95% internationally.
The world's most famous carbon fiber company is Japan's Toray. Energy production T1000 and MJ60. Of course, T800 can also be produced. In fact, the price of T800 is not high in the international market. T700 almost 17 USD/KG,
T800 is almost 35 USD/KG. Due to its large production and low cost, the gross profit margin of the above price of Toray T800 is basically about 20%. Since only the United States, Germany and Japan are above T700 and T800
The three countries can produce, so these three countries are prohibited from exporting to China in bulk. Therefore, the material of T800 is less in China and the price is high. The current market price is almost 1000RMB to 1200RMB/KG.
It is precisely because of the small number of Chinese J-fighters that T800 materials cannot be used. T300 materials are basically used in current service, and the utilization rate is also low, almost 10% to 15%. while Boeing and Airbus
The use of T800 materials for civil aircraft is now basically greater than 50%. Therefore, the crux of the problem lies in 1. How much is the cost of the aviation department? 2. Even if it is produced, what is the price for national use? Only in this way can
Calculate the gross margin. If the current market price of Toray products in China is calculated, I think the Aviation Department will make a big difference. Of course, 100 tons can't be sent anywhere. Only thousands of tons, after reducing costs to expand production is a big.
I think this is also the reason why urban construction invests thousands of tons. Of course, the country is not a fool, and Japan Virtue is not a fool either. Will the country give you a good price when you mass produce it? Japan Virtue, don't you want to dump it? So, it was fought at that time.
Is the quality and support of domestic products. Of course, if I were the boss, the best thing to do would be to sign a pricing quantitative agreement with the country before completing development. On the other hand, in 2013, the aviation department was the key support of the state.
One of six carbon fiber companies. The purpose is for civil aircraft. I think it is more troublesome to change materials for military aircraft. I don't know how long it will take to test them. Of course, the new US military aircraft now uses T800
All reached 50% or even more than 60%. This is also one of the most important aspects of the advanced US aircraft.
Jiangsu Nantong Ruikong Technology production of 3-axis composite engraving machine, 4-axis carbon fiber pipe processing center, 5-axis carbon fiber cutting equipment, mainly using cutting and milling process and ultrasonic cutting process,
Solve the problem of finishing special-shaped products for Chinese carbon fiber composite materials. Welcome to advice!
