Abstract

The invention discloses a friction material and a brake pad comprising the same. The friction material comprises the following materials of a bonding material, a fiber material, a damping material, an antifriction material, a friction-increasing material, a filling material, an acidity-alkaline adjusting material, a metallic material and a heat-resistant reinforcement material. The brake pad is made from the friction material and has the characteristics of stable friction coefficient, good abrasion resistance, small aggressivity to a brake disc, good heat resistance and linearity, lowered noise, reduced metal using amount and easy machining and forming.

Description

technical field [0001] The invention relates to the field of vehicle braking, in particular to a friction material and a brake pad with the friction material. Background technique [0002] Brake pads are also called brake pads. In the braking system of a car, the brake pads are the most critical safety parts. The brake pads play a decisive role in the quality of all braking effects, so good brake pads are the protectors of people and cars. The working principle of the brake is mainly from friction, using the friction between the brake pad and the brake disc (drum) and the tire and the ground to convert the kinetic energy of the vehicle into heat energy after friction, and stop the car. A good and efficient braking system must be able to provide stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities, so as to ensure that the force exerted by the driver from the brake pedal can be fully and effectively transmi...
