Abstract

The invention relates to a high-strength automotive braking friction plate made of carbon fiber, ceramics and nano silicate, and a production method thereof. The braking friction plate mainly comprises raw materials such as carbon fiber, nano silicate, pottery clay, graphite, molybdenum disulfide, friction powder, resin, metal powder, nitrile rubber and inorganic adhesive. The production method comprises the following steps: thermally treating, stirring and mixing the raw materials, hot-pressing the raw materials by a single-layer hot press, then grinding the raw materials according to shape requirements of different products, and drilling the grinded raw materials to obtain the friction plate. The friction plate made of the materials can be suitable for various automobiles; and the strength of the product is improved by about one fourth, the high-temperature resistance and the stability are improved by one third, and the noise is reduced by one fourth.

Description

technical field [0001] The invention relates to a brake friction material, in particular to a carbon fiber ceramic nano silicate high-strength automobile brake friction plate and a production method thereof. Background technique [0002] With the rapid development of the automobile industry, automobile users have higher and higher requirements for braking safety performance. The original asbestos material friction plate is used in many developed countries due to the problems of toxicity, poor braking performance, poor heat resistance and weak strength. The country has already banned the use, and my country has begun to ban the use in 2003, and replaced it with new non-asbestos metal or semi-metal friction materials, such as organic fibers, metal fibers, silicon fibers, etc. For example, the Chinese Patent Gazette discloses some invention patents for non-asbestos friction materials, among which the asbestos-free brake friction material for patent application No. 99100005 consi...
