Description

technical field [0001] The invention relates to a composite friction material, in particular to a composite friction material based on controllable scale and dimension of carbon components and a preparation method thereof. Background technique [0002] The friction clutch uses the friction between the friction pairs to realize the engagement, separation or asynchronous operation of the mechanical mechanism or the active part of the machine and the driven part; the friction brake uses the friction between the friction pairs to realize the deceleration and speed limit of the mechanical mechanism or the machine or stop. The friction pair is composed of a friction plate and a dual plate, and the performance of the friction pair mainly depends on the friction and wear performance of the friction plate. With the development of mechanical devices to high load, high operating speed and high power, higher performance requirements are also put forward for friction devices, such as en...
