CARBON BRAKE PLATES

Friction carbon-carbon materials are widely used in aircraft brake systems and in practice has no equal due to their unique features:

• High thermal shock resistance. Such brakes better withstand power overload than brakes with ceramet plates;
• High and stable coefficient of friction in all operational modes;
• High energy absorption. Prevents other landing gear parts from overheating;
• High mechanical strength under static and dynamic loads in a wide temperature range;
• High wear resistance. Provides higher extension of brake service life in comparison with all used before materials;
• Small specific weight. Allows to reduce an aircraft gross mass in comparison with ceramet;
• Ecological safety.

Ceramet and carbon-carbon friction materials produced in Russia earlier for aircraft brakes were out of the modern technical requirements. First of all, their resource was less then 500 landings.

The state-of-the-art aircrafts require highly efficient carbon brakes; because of this AC "Rubin" initiated the development and production of friction carbon-carbon materials articles.

Due to continues design and quality analyzing systems that provide quality assurance through the whole technological path from the resources to the end product, AC "Rubin" in cooperation with the leading aircraft construction scientific and research centers developed an unconvencional and sophisticated technology with a short manufacturing cycle and originated a number of materials: Termar-DF-P, Termar-STD-U, Termar-ADF-OS, and Termar-FMM-SF.

These materials have more advantages in compassion with the former manufactured materials: the increased density, thermal conductivity, strength, wear-resistance, and stable friction characteristics. The operational characteristics  and the service live of products being made from new materials are highly competitive with that of the foreign analogs.

Brake plates being made of the stated materials were completely tested and are used now in brakes of operational airplanes Tu-160, Tu-204, Tu-214, Tu-334, An-124, An-148, Yak-130, S-80.
