JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
China Aerospace Science and Technology Corporation (CASTC) 5th institute successfully developed and produced large civil aircraft carbon brakes.
Aircraft brakes are consumable components that affect the safety of aircraft landing. Very few Chinese companies produce aircraft carbon brakes as its complicated manufacturing processes, demanding performance for its material properties, especially thehigh temperature friction.
To reverse the situation of import dependency of the domestic civil aircraft carbon brakes, China Aerospace Science and Technology Corporation (CASTC) 5th institute successfully developed and produced large civil aircraft carbon brakes. This achievement relies on its completely independent intellectual property rights aerospace composite materials core technology.
The 4th institute successfully obtained the Boeing 757-200 carbon brakes PMA approval and seven models carbon brakes maintenance license in 2004. It also got China first Airbus A320 series aircraft Brakes Parts Manufacturer Approval Certificate issued by the Civil Aviation Administration of China (CAAC).
Compared with traditional metal brakes, the 4th institute carbon brakes reduced weight by 40%, and the expected life is more than 3,000 times. This number is 42% higher than the foreign original organic carbon disk (2100 ups and downs). It can prolong life for3 to 5 times with high reliability and maintainability. The product has been extensively used in the Boeing 757 series aircrafts. It accounts for more than 50% of China aircraft market. The annual output is more than $ 10 million.
Brake system is the second largest consumable repair parts in civil aircraft after the aircraft engines. Its localization will bring more convenient services for the domestic airlines, and the cost is only 50% to 60% of the imports.
