Ceramic Matrix Composite, CMC, Carbon-Ceramic Brake Discs
Description
Carbon-ceramic brake discs are part of a special class of materials called ceramic matrix composites, often abbreviated with the acronym CMC. These innovative discs were born during the 1970s in the aerospace field. Only in the following decade, the first applications for motorsport arrived. Carbon ceramic brakes (a.k.a. ceramic composite brake discs or CC brakes) are one of the most common types of disc brakes found in high-performance cars like Ferraris.

Advantage
Compared to traditional cast-iron brake discs, CMC ones are lighter in weight by up to 50%. In addition, the ceramic matrix has properties typical of advanced ceramic materials, such as:
high hardness even at high temperatures
greater wear resistance
low deformation at high temperatures
excellent resistance to corrosion
Work Application
All these features make CMC brake discs ideal in:
- limiting the effect of fading, that is the loss of effectiveness of the braking system following long or repeated braking
- increasing the useful life of the discs
Composite materials with ceramic matrix
Ceramic matrix composite materials are a solution to the limit that advanced ceramics present for structural applications. Carbon-ceramic brake discs are made of a ceramic matrix (usually silicon carbide), and of high-strength carbon or silicon carbide fibers.
