C/C-SiC Brake Discs

Semicorex C/C-SiC brake discs are high-performance braking components made from an innovative carbon-silicon composite material. These discs incorporate a three-dimensional structure, created from carbon fiber felt or woven materials, which serves as a reinforcing skeleton. The matrix consists of both carbon (C) and silicon carbide (SiC), resulting in a dual-matrix composite. This unique combination of materials leverages the advantages of both carbon and silicon carbide, making it an ideal choice for high-performance braking systems.

C/C-SiC brake discs are characterized by high toughness and low density. The carbon-based matrix provides excellent resilience, reducing the risk of brittle failure under extreme stress. Their lightweight composition contributes to improved vehicle performance and fuel efficiency. These brake discs also exhibit outstanding thermal stability and heat resistance, maintaining their structural integrity at temperatures of at least 1650°C without degradation. This capability ensures reliable braking even under the most demanding conditions. Additionally, their superior wear resistance and high hardness significantly extend their service life compared to conventional brake materials, while the presence of SiC enhances surface hardness, minimizing brake wear and improving overall durability.

This C/C-SiC brake discs do not only performs well under high temperature conditions, but also solves the problem of low friction coefficient of carbon-carbon brake pads under low temperature and wet conditions, making carbon-ceramic brake pads not only applicable in the high-temperature racing field, but also in civilian applications.

The composite structure of C/C-SiC brake discs offers excellent resistance to thermal shocks, preventing cracks and fractures that can occur with rapid temperature fluctuations during braking. Furthermore, the inclusion of SiC increases oxidation resistance, ensuring long-term performance and reliability in high-temperature environments. The production of these brake discs involves a two-step process: first, a carbon-carbon (C/C) composite is fabricated using carbon fiber reinforcements within a carbon matrix. The second stage involves liquid silicon infiltration (LSI) or reactive melt infiltration (RMI) to introduce SiC into the matrix, further enhancing the mechanical and thermal properties of the material.

C/C-SiC brake discs are widely used in industries where braking performance is critical, particularly in high-speed, high-load, and high-temperature situations. They are employed in advanced fighter jets, high-speed trains, and motorsports. In aerospace applications, these discs deliver unparalleled heat resistance and durability, ensuring optimal performance for military and aviation needs. High-speed trains rely on these discs for efficient and safe braking under extreme operational conditions, while motorsports and supercars benefit from their lightweight structure and superior braking capabilities.

With their unique material composition and enhanced mechanical properties, C/C-SiC brake discs set the benchmark for next-generation braking technology. Their adoption in cutting-edge aerospace, automotive, and rail applications underscores their exceptional performance in extreme environments. As industries continue to push the boundaries of speed and efficiency, C/C-SiC brake discs remain a crucial component in meeting the highest standards of braking safety and reliability.
