Abstract

The invention belongs to the technical field of friction sheets, and relates to a high-performance ceramic friction sheet and a production process thereof. The high-performance ceramic friction sheet consists of the following substances in parts by weight of: 60 to 68 parts of copper, 10 to 15 parts of ferrum, 2 to 5 parts of tin, 5 to 10 parts of silica, 3 to 8 parts of molybdenum disulfide, 5 to 10 parts of calcium aluminate, 5 to 13 parts of graphite and 0.5 to 1.5 parts of kerosene. The production process of the friction sheet comprises the following steps of: mixing materials; pressing and forming; and sintering and detecting under a dry working environment. The high-performance ceramic friction sheet has the beneficial effects of high friction performance, high compression strength and low abrasion rate; and when the high-performance ceramic friction sheet is used, the number of produced gas and the number of produced powder are small, the environment pollution is low, and the high-performance ceramic friction sheet brakes steadily, softly, safely and reliably.

Description

technical field [0001] The invention belongs to the technical field of friction plates, in particular to a high-performance ceramic friction plate and its production process. Background technique [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmit kinetic energy. Any mechanical equipment and various moving vehicles must have braking or transmission devices. Friction material is a critical component on this braking or transmission. Its main function is to absorb or transmit power through friction. For example, the clutch plate transmits power, and the brake plate absorbs kinetic energy. They enable mechanical equipment and various motor vehicles to work safely and reliably. So the friction material is a widely used and crucial material. [0003] Especially in recent years, with the rapid development of the automobile industry, people have higher and higher requirements for braking performance...
