Friction plate structure and manufacturing method thereof

Abstract

The invention provides a friction plate structure and a manufacturing method thereof. The thickness of the friction plate structure ranges from 0.45 mm to 1 mm, and the friction plate structure is formed by laminating a carbon fiber sheet, an adhesive material, a support material, an adhesive material, and another carbon fiber sheet orderly, wherein the carbon fiber cloth is formed by weaving a plurality of fiber bundles in a staggered manner, each fiber bundle is formed by twisting a plurality of short fibers and locally overlapping and interwinding the plurality of short fibers in the axialdirection of the fiber bundle, and the length direction of each short fiber corresponds to the axial direction of the fiber bundles; the bonding material permeates into the fiber bundles of the carbonfiber cloth until the impregnation rate is greater than 80%, and the fiber bundles of the carbon fiber cloth are partially exposed out of the bonding material in a peak area of a wave crest. The radial tensile strength of the friction plate structure ranges from 90 MPa to 177 MPa, the axial tensile strength of the friction plate structure ranges from 60 MPa to 136 MPa, and the dynamic and staticfriction ratio of the friction plate structure ranges from 0.8 to 0.98.

Description

technical field [0001] The invention relates to a friction plate structure, in particular to a friction plate structure containing discontinuous carbon fiber and highly impregnated and self-lubricated by resin and a manufacturing method thereof. Background technique [0002] Friction material is a necessity applied to power machinery. Its principle of action is mainly to rely on the friction relationship between the friction material and the dual mechanical device to produce the effect of power transmission or braking. Most mechanical appliances or equipment are equipped with friction materials, so the quality of the friction materials directly affects the performance of the mechanical appliances or equipment, and even relates to the life safety of operators. [0003] At present, the friction plate materials used in power machinery mainly include asbestos, metal or paper-based materials, all of which have their defects or limitations, such as: [0004] The earliest develope...

AI Technical Summary

Problems solved by technology

[0005] The friction plate made of metal has the problem of metal corrosion, and it is also easy to produce harsh and sharp noises due to excessive wear or unevenness of the surface of the friction plate during use

[0006] The paper-based friction plate has the advantage of relatively low material cost, but its friction performance is relatively limited, and its durability is not good. Its structure cannot bear excessive friction consumption, so it can only be used in mechanical friction with low demand. In the field of machinery, it is not enough for high-end machinery with high friction performance requirements
