Problems solved by technology

For a long time, automobile brake pads mostly use semi-metallic brake pads. Semi-metallic brake pads contain a large amount of heavy metal substances, which will release harmful substances to the environment during the braking process. This is contrary to my country's ideal of green environmental protection; The braking performance of the disc is unstable, the material hardness is high, the thermal conductivity is low, the friction coefficient is unstable, and the excessive braking noise generated during the braking process greatly reduces the comfort

technical field [0001] The invention relates to a bionic double-layer structure ceramic brake pad and a preparation method thereof, belonging to the field of auto parts. Background technique [0002] With the rapid development of new energy vehicles, automobiles are developing in the direction of green manufacturing, energy reduction and emission reduction, and more and more stringent requirements are placed on automobile braking systems. Brake pads, as one of the most critical parts of the braking system, mainly use the friction base material to produce a friction effect by bearing the braking force to achieve the purpose of decelerating the vehicle. For a long time, automobile brake pads mostly use semi-metallic brake pads. Semi-metallic brake pads contain a large amount of heavy metal substances, which will release harmful substances to the environment during the braking process. The braking performance of the disc is unstable, the material has high hardness, low thermal...
