HNSX Carbon Ceramic Composite Material Technology Corporation is engaged in the R&D and manufacturing of ceramic-matrix composite materials.
Carbon fiber reinforced silicon carbide composites has the characteristics of high temperature friction resistance, and is an ideal material for the production of brake discs and other high temperature resistant structural parts.
HNSX and the Chinese Academy of Sciences jointly carried out research on Carbon fiber reinforced silicon carbide composites Technology,
From the Chinese Academy of Sciences:
Academician Zhang Litong is mainly engaged in the research of aerospace high-temperature ceramic-matrix composite materials
Academician Huang Boyun has long been engaged in the research and development of advanced composite materials, high-performance friction materials, high-temperature structural materials, powder metallurgy materials and other new materials.
In 2004, the Carbon fiber reinforced silicon carbide composite materials and ceramic matrix composite materials projects studied by the two academicians won the first prize of the National Technical Invention, which ended the six-year history of this award vacancy.
On June 18, 2019, HNSX produced Carbon fiber reinforced silicon carbide composite brake discs and brake pads for a 400km / h high-speed train.
“China’s high-speed train brake discs were previously made of steel materials, and 80% or 90% of them were imported or supplied by joint ventures or foreign-funded enterprises, now Carbon fiber reinforced silicon carbide composite brake discs developed by HNSX Solved the problem of localization.
Compared with traditional materials, Carbon fiber reinforced silicon carbide composite materials are lighter in weight, more energy-saving and noise-reducing. At the same time, Carbon fiber reinforced silicon carbide composite materials are also resistant to oxidation, can withstand high temperatures of 2000 ° C, and have good toughness and are not easy to wear. “The weight of a Carbon fiber reinforced silicon carbide composite brake disc is one-fourth that of traditional steel materials, which can reduce the weight of each train by 10 tons, greatly reducing noise and doubling the service life.”
From the first time the concept of “Carbon fiber reinforced silicon carbide composites material” was proposed, to industry recognition, and then to its successful application in key equipment projects. HNSX took almost 20 years.
During the research period, “High-PerformanceCarbon fiber reinforced silicon carbide composite Materials and Applications” was selected as the national high-tech research and development plan.
In 2012, the Carbon fiber reinforced silicon carbide composite brake disc passed the 420 km / h bench test, which is currently the highest speed.
In 2013，HNSX developed Carbon fiber reinforced silicon carbide composite (C/SiC) brake discs for automotive…
After that, the HNSX R & D team began to pave the way for the industrialization of Carbon fiber reinforced silicon carbide composites materials.
Subsequently, Carbon fiber reinforced silicon carbide composites materials and their products were gradually applied to high-speed trains, light rails, subways, automobiles, tanks, military aircraft, aerospace and other fields.
