The B757-200 aircraft carbon brake disc produced by Super Code was approved by the parts manufacturer (No. PMA0044) issued by the Civil Aviation Administration of China in May 2004.

Technical characteristics and advanced evaluation:

1. Integral preform forming technology of needle-punched non-weft cloth quasi-three-directional structure;

2. The optimized combination preparation technology with roughened layer pyrolytic carbon as the main body and resin carbon as the supplement 3 shed-silicon series or modified phosphate series anti-oxidation coating.

The carbon/carbon brake discs produced by Super Code Technology have the outstanding characteristics of high mechanical properties, large thermal conductivity, good friction characteristics, and long service life. They are obviously better than similar products imported from abroad. The braking performance of aircraft suspension and wet brakes It is better than foreign original carbon/carbon brake discs, and its comprehensive performance has reached the advanced level of similar products in the world.

Technology maturity assessment:

Since the B757-200 aircraft carbon/carbon brake disc was approved by the parts manufacturer issued by the Civil Aviation Administration of China in May 2004, dozens of batches of aircraft carbon/carbon brake disc density, mechanical properties, thermal properties, friction performance and other test indicators have all passed the inspection. In China International Aviation Co., Ltd. and other units installed more than 1300 sets, the use of good condition, stable and reliable quality.
