Abstract

The invention relates to the technical field of friction materials, in particular to a carbon-based ceramic brake block and a preparing method of the carbon-based ceramic brake block. Through the proper proportioning and combination of raw materials such as carbon fiber, ceramic fiber, aramid fiber, phenolic resin, mineral fiber, blanc fixe, modified silicon carbide, friction modifying agents, inorganic lubricating agents, organic friction powder, tougheners and improving agents are properly mixed and combined, so that the raw material formula of the carbon-based ceramic brake block is reasonable, in addition, through the steps of raw material mixing, molding pressing forming, heat treatment and grinding in the preparing process, the manufacturing technical flow process of the carbon-based ceramic brake block is shorter, the production period is short, the production cost is low, and the obvious economic benefits are realized; in addition, the friction coefficient and the abrasion degree of the prepared carbon-based ceramic brake block are better through being compared with the brake block produced by manufacturers of products produced according to the GB5763-2008 standard and the domestic automobile brake technology.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to a carbon-based ceramic brake pad and a preparation method thereof. Background technique [0002] Friction material is a metal or non-metallic composite material mainly used to manufacture various brake and transmission parts with wear resistance and high temperature resistance. Such as automobile brake pads, also known as brake pads. According to different purposes, it can be divided into service brake and parking brake. At present, the research on automobile brake pads has been relatively abundant, and its literature volume is relatively large. The main research tends to be wear-resistant, excellent friction performance, high temperature resistance, and not easy to slip, that is, to improve the braking effect and reduce the safety factor. [0003] However, for the research on brake pads at home and abroad, although there are a large number of technical documents an...
