What is friction material?
Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. It mainly includes brake linings (brake pads) and clutch facings (clutch plates).
The friction material belongs to the polymer ternary composite material, which consists of three parts:
1. Use polymer compounds as binders;
2. Use inorganic or organic fibers as reinforcing components;
3. Use fillers as friction modifiers or compounding agents.
According to the function, it can be divided into two categories of transmission and braking friction materials. For example, the clutch plate of the transmission function transmits the power generated by the engine to the driving wheel through the bonding and separation of the clutch friction surface in the clutch assembly, so that the vehicle starts to walk. Brake pads for braking (divided into disc type and drum type brake pads), are used to stick the brake pads to the brake disc (drum) through the vehicle braking mechanism to slow down or stop the moving vehicle.
