Problems solved by technology
However, most of the semi-metallic and asbestos-free brake pads cannot fully adapt to complex and harsh braking conditions and higher environmental protection requirements, especially in high-speed, heavy-duty and other braking conditions.
Semi-metallic brake pads have high braking noise, are easy to damage the counterpart, are easy to rust, and are easy to cause friction performance degradation; non-asbestos brake pads will release harmful gases after high-temperature friction and are prone to thermal decay, causing brake failure and causing major safety hazards. Accidents, causing huge economic losses to people
The existing friction materials for brake pads have gradually realized the effect of excellent performance of some brake pads through the change and addition of various components, but at the same time, there are inevitably one or more poor performances, which affect people's User experience and safety performance

Description
technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a friction material for a brake pad and a manufacturing method thereof. Background technique [0002] Friction materials are composed of polymer binders, reinforcing fibers, friction modifiers and other ingredients. They are products made through a series of production and processing. They are widely used in automobiles, trains, airplanes, petroleum, etc. Drilling rigs and other construction machinery and equipment. [0003] Traditional automobile brake pads usually use asbestos friction materials, semi-metal friction materials or asbestos-free organic friction materials. Asbestos brake pads have been replaced by semi-metallic and asbestos-free organic friction materials due to their unstable high-temperature friction performance, high braking noise, short service life and strong carcinogenicity. However, most semi-metallic and asbestos-free brake pads cannot fully adapt...
