What types of brake pads are there?
With the improvement of people's living standards, friction materials for friction plates have been closely connected with everyone. In people's daily life, we can see the convenience brought by various friction materials for friction plates, which can be roughly divided into the following categories.
1. Rubber-based friction material: the main formula of this kind of friction material friction plate is rubber, cork and fiber, which does not contain asbestos, which can not only play a good friction coefficient, but also achieve wear resistance, no noise and environmental protection. It is a material commonly used in motorcycle clutches.
2. Paper-based friction material: This kind of friction material friction plate is mainly made of imported carbon fiber, aramid fiber and imported resin. It can be used for racing cars and large-displacement motorcycles, especially its friction coefficient is very stable. High-temperature friction coefficient decay is very small, ablation resistance, and thermal recovery performance is good (after the high-temperature clutch slips, the friction coefficient quickly returns to the original state after the clutch cools down).
3. Resin-based friction material: This kind of friction material friction plate is mainly made of reinforced fiber, friction powder and resin. It has the characteristics of high hardness, wear resistance, and high temperature resistance of 350 degrees. It is mainly used in various machinery On the clutch and motor reducer, its various performances are comparable to those imported from Taiwan.
4. Carbon fiber friction material: This kind of friction material friction plate is mainly made of carbon fiber, imported rubber and imported cork as the main raw materials, processed by high-quality technology, with high temperature resistance of 350 degrees, wear resistance of 25000 kilometers, no noise, no It has the characteristics of slipping and ablation resistance, and is a high-quality product among friction materials.
5. Semi-metallic friction material: This kind of friction material friction plate is mainly made of rubber, friction powder, fiber and metal fiber. The product has the characteristics of wear resistance, super hardness and high friction coefficient. It is used in mechanical clutches and The best partner on the motor braking system.
Requirements for the fiber components used in brake friction lining friction materials:
1. The enhancement effect is good.
2. Good heat resistance, no fusing, carbonization and thermal decomposition will occur under the friction working temperature.
3. Has a basic coefficient of friction.
4. The hardness should not be too high, so as not to generate braking noise and damage the brake disc or drum, and the process has good operability.
5. Filler The filler in the friction material component is mainly composed of friction performance modifier and compounding agent.
