HNBY New Material Co., Ltd. is a high-tech enterprise founded by the Chinese Academy of Engineering, former President of Central South University, and doctoral supervisor Huang Boyun.
The company is located in Changsha National High-tech Industrial Development Zone, Hunan Province. It was restructured from the Powder Metallurgy Research Institute of Central South University in July 2001. The company's registered capital is 470 million yuan. There are more than 500 employees, including 1 academician, 10 doctors, 25 masters, and nearly 200 with bachelor degree or above. Three subsidiaries: Hunan Boyun Oriental Powder Metallurgy Co., Ltd., Changsha Xinhang Wheel Brake Co., Ltd., Changsha Weihui Hi-tech New Materials Co., Ltd., and Honeywell jointly established Honeywell Boyun Aviation System (Hunan) Co., Ltd., providing wheel brake system for domestic large passenger aircraft C919. In September 2009, Boyun New Materials A shares were issued and listed on the Shenzhen Stock Exchange, stock code: 002297.
The company is mainly engaged in powder metallurgy and carbon / carbon composite materials for aviation brake pairs, aerospace and civilian carbon / carbon composite products, high-performance mold materials, aircraft wheels and brake systems, rare metal ultra-fine powder materials, powder metallurgy professional equipment, etc. Research, development, production and sales of products. The company has formed a product line with completely independent intellectual property rights. The company has established a complete quality management system, and has passed ISO9001-2000 quality management system and GJB9001A-2001 quality management system certification.
The company's products involve aviation, aerospace, railway, automotive, metallurgy, chemical and other fields. A variety of aircraft brake pairs have been widely used in various types of aircraft, and some products are also exported to Southeast Asia, Russia and other CIS countries. A variety of independently developed carbon / carbon composite nozzles have been successfully used in space vehicles.
Carbon / carbon composite material
Carbon / carbon composite material is an advanced composite material reinforced with a carbon fiber matrix. It has a series of excellent properties such as low density, high specific strength, excellent friction characteristics, high temperature resistance, and thermal shock resistance. It is widely used as a thermal structural material. Used in aviation, aerospace, automotive, nuclear energy, machinery, chemical and other fields. The characteristics of light weight, good braking performance and excellent high temperature ablation performance of carbon / carbon composite materials make it the best aerospace braking material and space rocket engine nozzle material.
The company has developed a series of carbon / carbon composite material preparation technology and process equipment with independent intellectual property rights, and formed nearly 20 system-integrated inventions and innovations. Among them, "Preparation technology of high-performance charcoal / charcoal aviation braking materials" won the first prize of 2004 national technology invention. The company is the first company in China to obtain the approval letter from the China Civil Aviation Administration for the manufacture of carbon brake auxiliary parts for large civil airliners. The company's products have been widely used in ultra-high temperature parts of aerospace engines. The carbon / carbon composite materials civilian products developed by the company have been widely used in semiconductor industry, metallurgy, chemical industry and other fields.
High-performance powder metallurgical friction materials
High-performance powder metallurgical friction materials have high friction coefficient, stable braking, high temperature resistance, long life, wear resistance and other excellent properties. They are widely used in aerospace, aviation, marine, train, automobile and engineering machinery and other fields.
HNBY New Materials has successfully developed powder metallurgy brake pairs such as Trident, Boeing 737, McDonnell Dow 82, Tu 154, Yak 42, Yier 96, and Su XX / XX, and supplied them to the market in batches. The developed aviation brake pair and technology level fully meet the requirements for use and reach the world advanced level. The company's next-generation Boeing-737 series aircraft brake sets are gradually replacing imported products and exported to other countries.
