Structural components of friction materials
Reinforced fibres
Fibre reinforced material constitutes the base material of friction material, which gives the friction products enough mechanical strength to withstand the load force of grinding and riveting processing during the production process of friction pads, as well as the impact force, shear force and pressure generated by the braking and transmission during the use process.
China's standards and automobile manufacturers according to the actual use of the friction plate working conditions, the friction plate put forward the corresponding mechanical strength requirements. Such as: impact strength, bending strength, compressive strength, shear strength. In order to meet these strong performance requirements, the need to choose the appropriate fibre varieties to increase and meet the strength properties.
Friction material on its use of fibre component requirements:
(1) Good enhancement effect.
(2) good heat resistance. In the friction working temperature does not melt, carbonisation and thermal decomposition.
(3) Basic coefficient of friction.
(4) The hardness should not be too high to avoid brake noise and damage to the brake disc or drum.
(5) Good process operability.
