Problems solved by technology

The above three types of resins have their own shortcomings. Unmodified phenolic resin has general high temperature resistance and general elasticity. Brake pads made of high temperature resistant modified phenolic resin have poor elasticity and high hardness. Modified phenolic resin with enhanced elasticity has high temperature resistance. poor performance
[0003] Carbon materials can improve the high temperature resistance of brake pads, among which carbon fiber has an excellent reinforcing effect, graphite materials have a lubricating effect, hard carbon materials can enhance the overall wear resistance of friction materials, and can significantly improve the wear resistance of friction materials. High temperature and high speed performance, but often a carbon material used in conjunction with an adhesive will have certain shortcomings

The multielement resin base carbon compound disc-type braking pad also has the function of automatically cleaning the braking disc.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a multi-component resin-based carbon composite disc brake pad and a preparation method thereof. Background technique [0002] Traditional automobile brake pads are made of a single phenolic resin as a binder, which is mixed with reinforcing fibers and friction performance regulators in a certain proportion and then hot-pressed. According to the use of phenolic resin, there are three main categories: unmodified phenolic resin, high temperature resistant modified phenolic resin and elastic modified phenolic resin. The above three types of resins have their own shortcomings. Unmodified phenolic resin has general high temperature resistance and general elasticity. Brake pads made of high temperature resistant modified phenolic resin have poor elasticity and high hardness. Modified phenolic resin with enhanced elasticity has high temperature resistance. Poor performance. [0003]...
