The brake division
belongs to the "systems and advanced materials"
departement. Two types of friction materials have
been elaborated there :
- the sinter metal material
- the carbone/carbone composite
The carbone/carbone composite materials are essentialy
used for planes applications. They permit to absorb
the energy by an urgent braking (an Airbus which
is flying at 320Km/h has to stop in 1200 m) and
work at more than 1600°C. Carbone Lorraine is
the main suplier for the Airbus A321 range.

| In car racing, Carbone
Lorraine offers a carbone/carbone range for brakes
and clutches equipement. The disc and the pads are
made of carbone/carbone. This material is also used
in F1 (clutches and brakes). In this case, it associates
lightness and a high brake capacity. |
 |
The sinter metal
materials have a larger range of applications:
- the brakes of the TGV, the high speed locomotives
and freight waggon are made of sinter metal products,
because of heavy masses to brake or very high speeds
(a TGV speeding at 320 Km/h must stop in 3000 m). |
 |
| Carbone Lorraine
is also active in aeronautic, with the Airbus A300,
A310, Mirage F1 and Sikorsky and Tiger helicopters.
Sinter metal materials brakes also military vehicules
like the AMX30 and AMX10 tanks. |
 |
| Because of high
braking energies, the industrial brakes for windmills,
or mines conveyors needed sinter metal products. |
 |
| More recently, Carbone
Lorraine developped a range of pads for racing cars
(rally, tracks...). The product equips official
teams in world rally championship (WRC). |
 |
| The last big product
family of Carbone Lorraine concerns the motorcycles
brake pads. The material gives: longevity, power,
feeling, moderability and perfect use under rain.
Each application is adapted to the product. |
