Embodiment Construction

[0033]A brake pad with coconut fiber as the skeleton uses a three-dimensional braided composite material prepared from coconut fiber as a reinforced skeleton. First, the natural coconut fiber is woven into a three-dimensional integral fabric with the same size as the brake pad, and then the molding process is used to inject resin, filler and Friction performance regulator, etc., and finally solidified by squeeze casting process to form high-performance automobile brake pads. The product can not only meet the performance requirements of automobiles on friction coefficient, wear rate, hardness, impact toughness, etc., but also has the advantages of no noise during braking and no pollution to the environment.

Abstract

A brake pad taking coir fibers as a framework mainly comprises the coir fibers, FKF compound mineral fibers, aramid fibrils, rare earth modified phenolic resin, a titanate coupling agent, nonionic polyacrylamide, carbon monofluoride, flexible coke, molybdenum disulfide, flake aluminium powder, hollow microsphere powder and calcium sulfate whiskers. Firstly, the natural coir fibers are woven into a three-dimensional integral fabric consistent with the brake pad in size, the resin, filler, a friction performance modifier and the like are injected through a moulding technology, and finally the high-performance automobile brake pad is formed through curing by means of a squeeze casting technology. The product not only meets the requirements of automobiles for various properties such as the friction coefficient, abrasion rate, hardness and impact toughness but also has the advantages of having no noise during braking, causing no pollution to the environment and the like.

Description

technical field [0001] The invention relates to the technical field of brake pads for automobile braking, in particular to a brake pad with coconut fiber as a skeleton and a preparation method thereof. Background technique [0002] With the important changes in the production, technology and market conditions of the brake friction material industry at home and abroad, the brake material is facing a severe situation, and its performance requirements are getting higher and higher: it must have a sufficient and stable friction coefficient; The difference between the dynamic and static friction coefficients is small; it must have good thermal conductivity, large heat capacity and certain high-temperature mechanical strength; it must have good wear resistance and anti-adhesion, it is not easy to scratch the counterpart, and there is no noise; low cost, No pollution to the environment, etc. At present, the research and application of foreign friction materials are still comprehen...
