Ceramic brake pad and manufacturing technology thereof

Abstract

The invention relates to the technical field of automobile brake pads, in particular to an all-ceramic brake pad and a manufacturing process thereof. The beneficial effects of the ceramic brake pad and the manufacturing process thereof of the present invention are: the aramid fiber and Kevlar fiber used are a non-asbestos brake pad, which is not harmful to human health, does not drop ash, and is an environment-friendly product; Small specific gravity, no rust, stable friction coefficient, small thermal recession, no damage to the dual disc; suitable for various harsh conditions, no smoke, no sparks, safe braking; low noise, which can greatly reduce braking noise and reduce urban noise pollution; It has the characteristics of ceramics, stable braking, comfortable braking, high operating temperature; one-time molding, high production efficiency, high yield, and stable product quality.

Description

technical field [0001] The invention relates to the technical field of automobile brake pads, in particular to an all-ceramic brake pad and a manufacturing process thereof. Background technique [0002] Traditionally used automobile brake pads include asbestos-based, semi-metallic and low-metal brake pads. These types of brake pads have certain defects in application: asbestos-based brake pads have serious heat loss and are not suitable for high-speed braking, and asbestos is A carcinogen, which has been banned from use at present; semi-metallic brake pads are mainly composed of steel fibers as the skeleton material, phenolic resin as the binder, iron powder as the wear-resistant agent, and various functional fillers are added to compound it, and its specific gravity is large. , high brittleness, high friction temperature, high low-frequency noise, large dual wear and severe high-temperature recession, which can easily cause high-temperature brake failure and seriously affec...
