A: Carbon-Carbon composites offer two main advantages: weight reduction and thermal stability. C/C brakes are approximately 60% lighter than steel equivalents, which translates to significant fuel savings and increased payload. Furthermore, while steel's friction performance decreases as it gets hotter, C/C composites actually maintain or even improve their friction coefficient at high temperatures, ensuring safer landings.
A: The service life (Landings Per Overhaul) depends on the aircraft type and operating conditions. However, our advanced carbon fiber architecture is engineered for high durability, typically offering 1,500 to 2,000+ landings under standard commercial operating procedures, which significantly reduces the frequency of maintenance cycles compared to traditional materials.
A: Yes. CMCMAT specializes in the customized manufacture of aircraft brake components. We can produce rotors, stators, and pressure plates based on specific OEM drawings or performance requirements. Our precision CNC machining ensures that all tolerances meet the rigorous safety standards of the aviation industry.
A: Our aircraft brake heat sinks feature high thermal conductivity and optimized heat capacity. This allows for rapid heat dissipation during high-energy braking events, such as rejected take-offs (RTO). The superior thermal management prevents heat transfer to the landing gear and tires, enhancing overall aircraft safety.
A: At CMCMAT, we adhere to strict aerospace quality management systems. Our production processes for C/C composites and aircraft brake assemblies are strictly controlled to ensure consistent density, friction performance, and structural integrity, meeting the demanding reliability required for both civil and defense aviation.
