Abstract

The invention provides an ultrathin friction plate and a preparation method thereof. The ultrathin friction plate comprises a surface friction layer and a reinforced core plate covered with the surface friction layer, and the reinforced core plate comprises a carbon fiber center layer. The compressive strength and the surface friction coefficient of the ultrathin friction plate are both far betterthan those of an existing friction plate, thus, the thickness can be decreased to achieve the same technical parameter, and accordingly, the ultrathin friction plate is applied to an electromagneticbrake smaller in size. Moreover, due to the inherent fact that the density of carbon fiber cloth and the density of a phenolic resin based friction material are close, the ultrathin friction plate hasthe advantages of being low in gravity center eccentric degree and high in integrated degree.

Description

technical field [0001] The invention relates to the field of friction materials, in particular to an ultra-thin friction sheet and a preparation method thereof. Background technique [0002] The ultra-thin brake friction plates currently used in the market are reinforced with a stainless steel core plate inside the friction plates in order to meet the demand for strength. When this structure is pressed, it is impossible to ensure that the stainless steel core plate is in the center of the friction plate. At the same time, because the density of stainless steel is much higher than the density of the friction plate formula, it will cause the friction plate to be left and right due to the center of gravity not being centered during high-speed rotation. Oscillation will cause noise and increase the wear of the friction lining. Contents of the invention [0003] The invention provides an ultra-thin friction sheet and a preparation method thereof, aiming at solving the above-me...
