Carbon fiber is a very amazing new material. It is lighter than aluminum, but has stronger strength than steel. It also has excellent properties of high temperature resistance, corrosion resistance, impact resistance and fatigue resistance. It can be widely used. Aerospace, building construction, automotive industry and other manufacturing sectors.

Carbon fiber, as its name suggests, is a material that is "woven" from carbon wire. From a microscopic point of view, thousands of carbon atoms are twisted into a bundle of hemp ropes, and 24,000 carbon atoms are Large tow, the following is a small tow, in general, the smaller the manufacturing, the higher the difficulty, the more sophisticated the field of application.

Previously, as a national strategic level material, although China can come out early, high-quality small tow carbon fiber has been monopolized by the Japanese companies Tori, Toho and Mitsubishi, and the majority of the market share, and Taking this opportunity to sell to China at a high price, the higher-end high-mode M series small tow carbon fiber technology and products used in the aerospace industry are strictly prohibited from entering China.

In that case, thanks to the foreign blockade, we are no longer subject to people. Recently, there has been good news in the domestic Carbon fiber field. The effective width 1 meter carbon fiber microwave graphitization production line developed by Jinggong Group Co., Ltd. has made a major breakthrough. Conventional carbon wire microwave graphitization treatment, thereby increasing the modulus and strength of 15%, and finally producing products with quality above T800.

The production line is also capable of providing medium-high-high molds, high-strength medium-modules, and high-strength and high-modulus carbon fiber products of various grades. It is widely used in aerospace and defense industries, in addition to launch vehicles, "Dongfeng" intercontinental ballistic missiles. The core shell material is made of high performance small tow carbon fiber.

Carbon fiber is also expected to be used in tank armor. Of course, carbon fiber cannot be directly used as armor. Because carbon can be as strong as steel, it does not have metal toughness, which means that a little hole may cause the entire armor to collapse. If it is used as a filler in steel armor as a depleted uranium armor, the coexistence of hardness and toughness can be achieved.

The aircraft is the same, but because the aircraft is not too demanding on the weapon defense, the carbon fiber is light and strong, and the corrosion resistance can be said to be tailored for the aircraft casing. The lighter weight can improve the maneuver of the aircraft. Sex, and reduce noise, but also save fuel, can be described as profitable, of course, this is the application of ordinary carbon fiber.

Jinggong Group Co., Ltd.'s research and development results, the main key is microwave high-temperature graphitization technology, which can produce large tow from low-grade carbon fiber, medium and high modulus carbon fiber, reduce energy consumption by 70%, directly reduce 30% The cost is about to be applied to the carbon fiber launching cylinder of the "Fast Boat" 21st rocket carrying more than 20 tons.

Although we have not yet mastered the higher-end high-mode M-series small tow carbon fiber technology, in the 1000-ton large-strand carbon fiber project, which is the space rocket shell project, the rocket will still be reduced to a large extent. Manufacturing costs, with this technology, China's aviation industry will reduce an obstacle and take the lead for the future.

However, we still have to stay awake, and the relatively high technical difficulty of large tow carbon fiber technology has been successfully broken by China, but it is still in the stage of trial production. Japan and other established powers in this field are making big efforts to curb our development. The range is reduced by the price of carbon fiber, so even with large tow carbon fiber, the situation is still not optimistic.

Yancheng Xiangsheng Carbon fiber Technology Co., Ltd. is committed to researching the diversity and functionality of special fibers such as carbon fiber, aramid fiber and high modulus PE. It has independently developed a complete set of rotorcraft, landing gear, and plantation spray system for agricultural and forestry aircraft. , seaplane pontoons, wind-driven boats, aviation communication helmets, carbon fiber for plastic reinforcement, carbon fiber powder for friction materials, chopped carbon fiber for brake systems, carbon fiber rope, carbon fiber cloth, carbon fiber filament special fiber cutting machine, etc. It has 13 utility model patents, two invention patents, and one design patent.
