Overview
Carbon materials have high strengthand stiffness potential as well ashigh thermal and chemical stability
in inert environments. Thesematerials must, however, beprotected with coatings and/or
surface sealants when used in anoxidizing environment.

State of the art
Carbon-carbon (CC) materials are ageneric class of composites similar
to the graphite/epoxy family ofpolymer matrix composites.
These materials can be made in awide variety of forms, from one-dimensional to n-dimensional, using
unidirectional tows, tapes, or wovencloth. Because of their multiformit

The development of CC materialsbegan in 1958 and was nurtured
under the US Air Force space planeprogram, Dyna-Soar and NASA'sApollo projects. It was not until theSpace Shuttle Program that CC
material systems were intensivelyresearched.
The criteria that led to the selection

1) maintenance of reproduciblestrength levels at 1650C (3002F)
2) sufficient stiffness to resist flightloads and large thermal gradients
3) low coefficient of thermal expansion
to minimize induced thermalstresses
4) oxidation resistance sufficient to
limit strength reduction

Mercedes-Benz CL55 AMGF1
The Mercedes-Benz CL 55 AMG F1Limited Edition is the world's firstroadgoing automobile equipped with an
ultra-high-performance ceramic brakingsystem. The engineers atDaimlerChrysler AG and Mercedes-AMG
GmbH developed internally ventilatedbrake discs made from fiber-reinforcedceramics for this unique high-performance coupe. The use of ceramic
brakes in the CL was part of a pilot
