Abstract

The invention relates to an automobile brake pad adopting carbon fiber reinforced composite material, comprising a brake pad base material and a friction pad, the rear part of the brake pad base material is provided with a heat dissipation and sound-absorbing cavity; the outer periphery of the friction pad on the brake pad base material is provided with There is a hard surround; the hard surround is connected to the central friction plate located in the middle of the brake pad base material through the heat transfer sheet; the hinge joint is installed inside the heat dissipation and sound-absorbing cavity, and the heat-dissipating sound-absorbing shrapnel is arranged between the hinge joints; the heat dissipation The middle part of the sound-absorbing shrapnel is provided with a fixed connection spring, and the fixed connection spring is connected to the back of the base material of the brake pad; in the present invention, the carbon fiber modified resin is mixed with carbon fiber, and then other high-strength, high-hardness, and high-toughness materials are added to improve the In order to improve the rigidity, toughness and thermal conductivity of the brake pad, the present invention subtly divides the whole brake pad into four parts, and the four friction pads all brake the wheels at the same time. Tablet wear resistance and practicality.

Description

technical field [0001] The invention relates to the technical field of automobile brake pad design, in particular to an automobile brake pad using carbon fiber reinforced composite materials. Background technique [0002] Today, with the rapid development of the automobile industry, the safety and environmental protection of vehicles are particularly important, and people's new requirements for automobile brake pads are constantly increasing. Automobile brake pads are subjected to external pressure to generate friction during work, so that the vehicle can achieve the purpose of deceleration. Therefore, the wear resistance and heat resistance of the material of the brake pad are very important. In addition, the friction materials used in the automobile brake pads we use now contain many heavy metal substances, including antimony, chromium, cadmium, copper, barium, copper and other heavy metals. Every time a car brakes, a small amount of heavy metal dust is released and accu...
