BZNCarbon manufactures carbon-carbon composite brake discs for aircraft braking systems using proprietary 2.5D fiber-reinforced structures. These components are engineered to offer superior performance in high-load and high-temperature aviation environments. Our products are already in service across commercial aircraft fleets with proven reliability and durability.

Each brake disc is manufactured using advanced carbon fiber preforms, processed at temperatures exceeding 2000°C, and inspected using X-ray and non-destructive methods to ensure internal structural integrity. Custom geometries, densities, and profiles can be produced to meet individual aircraft models or retrofit requirements.

What Is a Carbon-Carbon Brake Disc?

Carbon-carbon brake discs are high-performance friction materials made from carbon fiber reinforcements within a carbon matrix. Unlike traditional metal discs, C/C brake components maintain mechanical strength and frictional performance at extreme temperatures without risk of warping, melting, or fading. They offer significant weight savings, extended wear life, and lower maintenance requirements.

Key Applications

Commercial jetliners (e.g. Boeing 757, Airbus A320, C919)
Military aircraft and unmanned aerial systems
High-speed aviation testing platforms
