Problems solved by technology

In the past technology, friction materials generally contain asbestos components to meet the requirements of high temperature resistance. However, during the production and use of friction materials with asbestos components, asbestos powder will be suspended in the air, which will easily cause air pollution and be harmful to the human body. Therefore, countries all over the world have successively developed non-asbestos friction materials

Abstract

The invention discloses a disc-type friction material and also discloses a manufacturing method of the disc-type friction material which has the advantages of capability of avoiding environmental pollution, good heat resistance, stable performance and high friction coefficient. The disc-type friction material contains 25-35 parts of steel fiber, 0.5-1.5 parts of aramid fiber, 24-30 parts of carbon substance, 7-9 parts of adhesive, 25-30 parts of barite powder and 21-22 parts of filler. The manufacturing method adopts dry preforming process and comprises the following steps: (1) mixing: putting partial steel fiber and partial aramid fiber and all the barite into a mixer, stirring, then putting in the rest materials and stirring again; (2) pre-compression molding: putting the mixed materials into a cold pressing mold and conducting pressure forming to obtain a cold billet; (3) hot pressing: putting the cold billet in a mold and pressing; and (4) heat treating: conducting heat treatment in a baking oven and baking for 9-19 hours at temperature raised from room temperature to 200 DEG C.

Description

technical field [0001] The invention relates to a disc friction material and a manufacturing method thereof. Background technique [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. It mainly includes brake linings (brake pads) and clutch surfaces (clutch plates). In the past technology, friction materials generally contain asbestos components to meet the requirements of high temperature resistance. However, during the production and use of friction materials with asbestos components, asbestos powder will be suspended in the air, which will easily cause air pollution and be harmful to the human body. Therefore, countries all over the world have developed non-asbestos friction materials one after another. However, with the rapid development of the automobile industry, automobiles and other means of transportation are developing in the direction of high speed, large size, and heavy l...
