Embodiment 1

[0026] 1. To improve the structural design of the prefabricated body, the present invention adopts a new carbon fiber prefabricated body with a "sandwich" structure. The "sandwich" C / C composite consists of a friction functional layer and a structural functional layer. The structural functional layer is a three-dimensional acupuncture structure, the structural functional layer is located in the middle of the material, and the frictional functional layer is located on the periphery of the material, and the two are connected as a whole through the relay acupuncture method. Among them, the structural functional layer is a typical three-dimensional needle-punched structure, which is the same as the structure of the three-dimensional needle-punched C fiber preform, and the frictional functional layer is a pure tire mesh structure, such as figure 1 Layers of "sandwich" structure shown.

Abstract

The invention aims at solving the problems that existing brake pad materials are unstable in frication performance, high in hardness, high in oscillation frequency, poor in automatic performance, uneven in frication and the like, and provides a novel modified prefabricated body carbon ceramic brake pad material and a manufacturingmethod thereof. The manufacturingmethod of the novel modified prefabricated body carbon ceramic brake pad material includes the steps ofusing a novel carbon fiber prefabricated body of a sandwich structure, preparing and processing fibers of a needled structure, manufacturing C / C porous bodies by adopting a slurry infiltration process, and introducing SiC-based, Si-based and B-based compounds into the carbon / ceramic porous prefabricated bodies;the puzzle that theresidual amount of Si is uncontrollable is effectively solved. According to the sandwich-shaped C / SiC brake material, stability of dry state frication performance is improved, the static friction coefficient is improved, and friction performance under a wet state condition does not attenuate.

Description

technical field [0001] The invention relates to a novel modified prefabricated carbon ceramic brake pad material and a manufacturing method thereof, belonging to the field of manufacturing auto parts. Background technique [0002] Brake pads are automatic parts that must be equipped with automobiles, trains, motorcycles, etc., and their performance directly affects the safety of vehicles and equipment. Brake materials with high wear resistance are the basis for safety guarantees such as vehicles. [0003] The original brake pad material was made of asbestos fiber material filled with phenolic resin. During its use, the high temperature produces thermal decay, which makes it lose its function. [0004] Organic binder brake pad materials are organic binder-based materials, containing about 30% to 50% of ferrous metals (steel fibers, reduced iron powder, foamed iron powder). This material has good heat resistance, high absorbed power per unit area, and high thermal conductiv...
