Also, the spiral micro-carbon fiber is contained, on one hand, a filling and reinforcing role can be played, the inherent vibration rate of the product is improved, and the noise is reduced; on the other hand, the spiral micro-carbon fiber is of a spiral spring type structure, so that the elastic modulus and hardness of the product are reduced, the adhesion among the various components is improved, the strength and toughness of the product are improved, the stability of the friction coefficient of the product is improved, the deterioration of heat resistance is avoided and the aggressiveness to friction duality can be effectively reduced.

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.
