Friction plates need to have good mechanical strength and physical properties
Before the friction plate is assembled and used, it needs to be drilled, riveted, assembled and other mechanical processing to make the brake pad assembly or clutch assembly.
During the friction work process, the friction material not only has to withstand high temperatures, but also withstands large pressure and shear forces. Therefore, friction materials are required to have sufficient mechanical strength to ensure that they will not be damaged or broken during processing or use.
For example: riveted friction discs: require certain impact strength, riveting stress, compressive strength, etc.
Bonded friction disc: The disc disc must have sufficient normal temperature bonding strength and high temperature (300°C) bonding strength to ensure that the friction material and the steel backing are firmly bonded and can withstand the high shear force of the disc disc during the braking process. , without causing mutual separation, causing serious consequences of braking failure.
The clutch friction plate is required to have sufficient impact strength, static bending strength, maximum strain value and rotational damage strength, in order to ensure that the clutch plate is not damaged during transportation and riveting processing, and to ensure that the clutch plate operates under high-speed rotating working conditions. No cracking occurred.
