What are the advantages of carbon ceramic brake discs?
Carbon ceramic brake disc is a brake disc made of carbon fiber reinforced silicon carbide-based composite material. It has the advantages of low density, high temperature resistance, high friction performance and stability, and has broad application prospects in high-energy braking fields such as automobiles, high-speed trains, and aircraft.
A distinctive feature of the carbon ceramic brake system is that it is made of ceramic composite materials. The carbon ceramic brake pad itself and the friction layers on both sides are made of carbon fiber reinforced silicon carbide material. The main matrix components are silicon carbide (SiC), Industrial silicon (Si) and carbon fiber (C).
Among them, silicon carbide determines the hardness of the composite material. The role of carbon fiber is to improve the mechanical strength of the material and provide the material with the fracture toughness required for technical applications. The characteristics of the ceramic composite material provide guarantee for its resistance to high thermal load and mechanical load. . Carbon fiber reinforced silicon carbide materials perfectly combine the physical properties of carbon fiber reinforced carbon (C/C) and polycrystalline silicon carbide ceramics.
Compared with traditional brake discs, carbon ceramic brake discs not only have excellent high temperature resistance, but also have the advantage of being lighter in weight due to the raw material carbon fiber. For brake discs of the same size, carbon ceramic brake discs are more than half lighter than traditional brake discs.
