Carbon based friction plates of powder metallurgy, and manufacturing technique

Abstract

This invention discloses a carbon-based friction disk for producing brake by powder metallurgy. The carbon-based friction disk is composed of: specifically treated carbon powder 20-40 wt.%, copper 15-30 wt.%, iron 5-15 wt.%, tin 2-5 wt.%, silicon dioxide 3-10 wt.%, manganese 0.5-2 wt.%, and phenolic resin 2-5 wt.%. The carbon-based friction disk has such advantages as high friction strength, uniform properties, simple process and low energy consumption.

Description

technical field [0001] The invention belongs to the friction material of the brake produced by the powder metallurgy method, and is especially suitable for the production of the friction plate of the plane, the automobile, the ship and the mining equipment. Background technique [0002] Early traditional friction materials include asbestos-based friction materials and copper-based friction materials. However, asbestos-based friction materials were eliminated due to the discovery that the powder contained carcinogens; although copper-based friction materials are still in use today, their wide application is affected by the relatively large dynamic and static friction coefficient and high cost. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the problems of the prior art, to provide a carbon-based friction material that strengthens the material matrix, enhances wear resistance, uses cheap raw materials to produce...
