Problems solved by technology

However, if the amount of metal fiber added is too small, the thermal conductivity effect is not ideal
Too much metal fiber is added, the friction coefficient decreases, and the metal fiber and the metal friction pair rub against each other during the friction process, resulting in sharp noise and at the same time causing wear and tear damage to the metal friction pair

Abstract

The invention discloses a plasma oxidized metal aluminum fiber reinforced friction material and a preparation method thereof. The material comprises a friction material and plasma oxidized metal aluminum fibers, wherein 300g of the plasma oxidized metal aluminum fibers are added into each cubic decimeter of the friction material.

Description

technical field [0001] The invention belongs to the field of preparation of friction materials, in particular to a plasma oxidation metal aluminum fiber reinforced friction material and a preparation method thereof. Background technique [0002] The friction material is a polymer-based composite material with a high coefficient of friction and a low wear rate. In order to ensure good wear resistance, inorganic particles with good wear resistance are usually added to the polymer binder to ensure that the friction material has good wear resistance. However, the heat generated by the friction material during the friction process will cause the friction material to soften, the friction coefficient will become smaller, and the wear rate will increase, thereby forming heat attenuation and reducing the service life. For this reason, metal fibers with high thermal conductivity are added to the friction material to increase the thermal conductivity of the friction material, ensure g...
