'We have produced high-end aerospace-grade carbon fiber products that have been applied to critical core equipment such as composite fairings on the 'Changzheng No. 11' launch vehicle, and have made new contributions to the aerospace industry. 'On May 22, Henan Energy & Chemical Industry Group Jurisdiction over the relevant person in charge of Wing Coal Carbon Fiber Co., Ltd. said to reporters.
According to the person in charge, carbon fiber products, especially space-grade high-end carbon fiber products, are indispensable new materials for cutting-edge technologies such as aerospace and military. Due to a variety of reasons, Japan, the United States, and other countries have been facing high-end carbon fiber production equipment and technologies. Our country has imposed a blockade. In the "Changzheng No. 11" launch vehicle launched in late April of this year, Henan Energy Chemical's carbon fiber products were applied.
Since 2010, Henan Energy Chemical Group has begun to undertake the R&D and production tasks for high-end aerospace-class carbon fiber. A carbon filament is only one-fourth the diameter of hair, from the raw material to the preparation of carbon fiber products, it must go through a 400-meter-long production line. With thousands of high-precision control parameters, a small change in process parameters can seriously affect the performance and quality stability of carbon fibers.
'R&D and production processes are difficult, but we are responsible for national projects. What we have accomplished is a big business. 'The person in charge said that over the past few years, they have solved more than 400 major technical problems and have broken through the low-carbon furnace waste row. Coke incineration and environmental protection discharge, Uniform control of sizing agent, Comprehensive utilization of production waste water resources, and environmental protection and other technical bottlenecks; Cracked the low-concentration acrylonitrile and dimethyl sulfoxide production wastewater treatment, dimethyl sulfoxide and water Reusing these technical problems that have plagued the carbon fiber industry for many years, realized the low-cost and environmentally-friendly treatment of production wastewater and the recycling of dimethyl sulfoxide, solved the equipment matching problem, and steadily improved product quality and yield. During the period, Yongye Carbon Fiber Company not only became the second-largest supplier of high-end carbon fiber products in China, but also was the only company with stable supply of MT300 and MT700 in the domestic aerospace system.
In the evaluation of the company's carbon fiber product stability, experts from China Aerospace Science and Technology Group unanimously agreed that Yongcheng’s carbon fiber products meet the standard requirements and agree to become a qualified supplier of non-metallic materials for China Aerospace Science and Technology Corporation.
'With the batch application of our company's carbon fiber products in the aerospace field, the leading role of aerospace applications has gradually emerged. Our market development in the military industry is also very smooth. Next, we will continue to increase research and development to boost brand upgrading. ' The company's general manager Li Zhipeng said.
