In the morning of June 18th, HNSX’s Carbon fiber reinforced silicon carbide ceramic matrix composites production line was put into production and the Carbon fiber reinforced silicon carbide ceramic matrix composites brake discs and brake pads for the 400-kph high-speed train were off-line. The Carbon fiber reinforced silicon carbide ceramic matrix composites products independently developed and manufactured by HNSX will be used on high-speed trains with a speed of 400 kilometers per hour.
Carbon fiber reinforced silicon carbide ceramic matrix composites is the perfect combination of carbon and ceramic, soft and hard. Compared with traditional materials,Carbon fiber reinforced silicon carbide ceramic matrix composites materials are lighter and more energy efficient. A Carbon fiber reinforced silicon carbide ceramic matrix composites brake disc is one-fourth the weight of traditional steel materials, which can reduce 10 tons per train, greatly reduce noise, and double the service life. Carbon fiber reinforced silicon carbide ceramic matrix composites is also resistant to oxidation, can withstand high temperature of 2000 ℃, and has good toughness, not easy to wear, strong stability, can be used in rainy and snowy weather.
The 400km / h high-speed train is a national key research and development plan project organized by the Ministry of Science and Technology, and the Carbon fiber reinforced silicon carbide ceramic matrix composites braking technology is one of 4 key technologies for high-speed passenger transport equipment with a speed of 400km / h or more.HNSX broke the technological monopoly of Germany, Japan and other countries and successfully solved a number of key technologies in the structural design, preparation, processing and application evaluation of Carbon fiber reinforced silicon carbide ceramic matrix composites brake discs for high-speed trains with a speed of 400km / h, which Strict evaluated by CRRC and delivered to CRRC Qingdao Sifang.
As a project of transformation of scientific research achievements of Central South University, HNSX has obtained 4 top qualification certifications at home and abroad.
The project for the development of Carbon fiber reinforced silicon carbide ceramic matrix composites brake discs for the EMU of China Railway Corporation, which solves the problem of enterprises entering the most advanced rail transportation in China The “threshold” of the product;
The company has also obtained the CRRC product research and production qualification, which means that the company has entered the CRRC supplier system; and it has the IRIS quality system certification of the International Railway Alliance, and its products enter the international market to participate in competition;
The company obtained the Chinese rail transit product supply and service qualification certificate, which solved the “identity” problem of the company’s mass application of rail transit vehicles. After the Carbon fiber reinforced silicon carbide ceramic matrix composites material production line is put into operation, the annual output value of HNSX is expected to reach more than 50 million yuan. Within 3 years, it can achieve an annual output value of 500 million yuan and the market share of high-speed train brake discs exceeds 20%.
