Abstract

The invention provides an electrochemically modified carbon cloth reinforced friction material and a preparation method thereof. The method uses carbon fiber cloth and modified phenolic resin as raw materials, treats the carbon cloth under electrochemical conditions, selects a composite nickel source as the electrolyte, and adopts Carbon fibers are treated by anodic oxidation and cathodic deposition of metallic nickel. Then spray the modified phenolic resin solution on the treated carbon cloth, take it out and dry it naturally, and use a vulcanizing machine to form it by hot pressing. In the present invention, the carbon cloth is anodized and cathodically Deposition treatment increases the oxygen-containing functional groups on the surface of carbon cloth and uniformly deposits metallic nickel. It has the advantages of simple equipment and high efficiency. Metallic nickel has high hardness, wear resistance and catalytic activity, which greatly improves the bonding strength between carbon cloth and resin. , thereby improving the uniformity of the network polymer formed by the linear polymer through crosslinking during the vulcanization process, so that it has better tribological properties.

Description

[0001] 【Technical field】

[0002] The invention belongs to the field of friction materials, in particular to an electrochemically modified carbon cloth reinforced friction material and a preparation method thereof.

[0003] 【Background technique】

[0004] Composite materials refer to materials that use one material as a matrix and another material as a reinforcement. Carbon fiber has the advantages of high specific strength, high specific modulus, high temperature resistance, corrosion resistance, and wear resistance. Carbon fiber cloth has good strength in both transverse and longitudinal directions, high load-bearing pressure and excellent tribological properties. In composite materials Medium is a reinforcement material with excellent performance. Carbon cloth reinforced resin composites are mainly used in automotive automatic transmissions, differentials, synchronizers, torque managers and other wet clutches.
