【Abstract】 According to recent development of the frictional brake material for automobile and theory of tribology and composite material, the flake reinforced vermiculite friction materials have been made out by varying the recipe and processing A mixture of flake material vermiculite and Kevlar fiber is used as the reinforcing bulk and a modified resin is used as the basic bulk Tests manifest that the properties of mechanics are high, friction factors are suitable and stable, noise is low and especially in high temperature wear is low. It is a new type of excellent automobile friction brake material as a replacement of asbestos friction materials更多还原
