Problems solved by technology

On the other hand, at present, most of the friction materials for automobiles at home and abroad use phenolic resin as a binder. During continuous braking and high-speed emergency braking, the surface temperature of the friction material rises sharply, and the friction coefficient drops sharply, causing thermal recession.
In severe cases, it will cause brake failure and cause an accident

Description

technical field [0001] The invention relates to a friction material, in particular to a resin-based friction material with low noise and heat decay resistance. Background technique [0002] The rapid development of the automobile industry, on the one hand, strengthens the connection between automobiles and people's lives, and brings great convenience to people's daily life, but while enjoying the modern civilization brought by automobiles, it also unconditionally bears the hazards, especially noise pollution. With the increasingly serious noise pollution and the continuous enhancement of people's awareness of environmental protection, it is particularly important to control noise pollution. On the other hand, at present, most of the friction materials for automobiles at home and abroad use phenolic resin as a binder. During continuous braking and high-speed emergency braking, the surface temperature of the friction material rises sharply, and the friction coefficient drops ...
