clutch plate, material

One important thing of the clutch plate is the used material of friction material.
There is a total contactarea of about 440 cm².

the material has to be resistant to the large amount of power.
One of the materials used is a kind of organic material:
Metal-fibres woven into "organic" (CF aramid with other materials)
advantages: long life, operating temperature, hard use possible
used for cars up to 400HP

In the friction material there are some grooves. Whats the fuction of them?
They will drain heat caused by friction, but also by a large pressure.
There will be always microscopic moves between f.e. the clutch plate and the flywheel. The friction will lead to very small particles of organic material. These have to been removed, because they act lik sandpaper for the same organic material.
They will also drain little drops of oil if there is a small leak. !!oil in the clutch will destroy the flywheel, clutch plate and pressure groep!!
