Composition of Friction Material - Reinforcing Fiber
The fiber reinforced material constitutes the base material of the friction material, which endows the friction product with sufficient mechanical strength, so that it can bear the load force of the grinding and riveting process of the friction plate during the production process and the friction caused by braking and transmission during use. Impact, shear, pressure.
my country's relevant standards and automobile manufacturers put forward corresponding mechanical strength requirements for the friction plate according to the actual working conditions of the friction plate. Such as: impact strength, flexural strength, compressive strength, shear strength, etc. In order to meet these strong performance requirements, it is necessary to select suitable fiber varieties to increase and meet the strength performance.
Friction material requirements for its fiber components:
1. The enhancement effect is good.
2. Good heat resistance. Fusing, carbonization and thermal decomposition will not occur at the friction working temperature.
3. Has a basic coefficient of friction.
4. The hardness should not be too high, so as not to produce brake noise and damage the brake disc or drum.
5. Good process operability.
