The composition of the friction material of ceramic brake pads


With the rapid development of science and technology, brake products have increased requirements for friction materials, and ceramic brake pads have achieved this. Ceramic brake pads provide safety and comfort in harsh environments such as high speed, high temperature and high pressure. Besides its high performance, it also has the advantages of energy saving, environmental protection and cleanliness.

The friction material itself is a friction material. Braking and transmission functions require a high coefficient of friction. Therefore, the friction-increasing filler is the main component of the friction performance modifier, and the friction-increasing effect of different fillers is different. The friction material is made from a mixture of different materials, it is a special material that works in a heat and high pressure environment, so it is required that the filler components used have good heat resistance, that is, thermal stability. Including thermophysical effects and thermochemical effects.

According to the function of the friction modifier in the friction material, it can be divided into "friction increasing filler" and "friction reducing filler". Proper use of fillers determines the characteristics of friction materials and is also very important in the manufacturing process. The following manufacturers of ceramic brake pads will help you understand.

Friction increasing material:

The Mohs hardness of a friction-increasing filler is typically 3-9. The effect of increasing friction of high hardness is obvious. Fillers with a hardness above 5.5 are solid fillers, but their dosage and particle size must be controlled.

Friction reducing material:

Anti-friction fillers, as a rule, are substances with low hardness, minerals with a hardness below 2 on the Mohs scale. Such as: graphite, molybdenum disulfide, talc, mica, etc. It can not only reduce the coefficient of friction, but also reduce the wear of the mating material, thereby increasing the service life of the friction material.
