Low-copper organic ceramic brake

Abstract

The invention discloses a low-copper organic ceramic brake comprising adhesives, a reinforcing material, friction performance modifier and filler. Polyacrylonitrile fibers having the advantages of high melting point, high modulus and stability in compression performance and potassium titanate lamella having the advantages of high stability in chemical resistance, high functional stability, good flexibility and the like are used for ingredients of friction materials, and the potassium titanate lamella is added, so that high-temperature friction performance is guaranteed, high-temperature wear of products is lower, no damage is caused to a friction pair, brake noise is reduced, high-temperature cracks are avoided, environmental pollution is reduced and the like.

Description

technical field [0001] The invention relates to a brake pad in the field of automobile industry, in particular to a low-copper organic ceramic brake pad. Background technique [0002] Brake pads, which are key parts of automobiles, are currently being developed from single materials to composite materials, and their quality directly affects the reliability of machines and the safety of operators. The speed, load and safety requirements of machinery are getting higher and higher. High-speed trains, heavy-duty trucks, cars, racing cars, motorcycles and other heavy-duty, high-speed driving, and frequent braking civilian vehicles all respond quickly and have high friction factors. However, there is an urgent demand for high-performance friction materials that are stable, have good thermal decay resistance, low density, long service life, strong environmental adaptability, and no pollution to the environment. Organic ceramic-based friction materials have emerged as the times requir...
