Automotive clutch disc to function is not available on video!

Clutch album is a kind of friction as the main function of composites, and structural requirements. Is mainly used in the manufacture of friction materials for automotive brakes and clutches. The friction material used
Asbestos friction material, along with the increasingly high requirements on environmental protection and safety, emerging half-metal friction materials, fiber composite friction materials, ceramic fiber friction material. Mainly used in the manufacture of brake friction material in automobiles and drive train parts, requires a sufficiently high and stable coefficient of friction and excellent wear resistance.
