| Abstract: | The basic technology and properties of the brake blocks made of modified needle-like wollastonite and fibrous sepiolite were
intensively researched. The impact strengthes and fixed velocity friction of the brake blocks prepared by different recipes
were tested. The testing results show that it is feasible for needle-like wollastonite and fibrous sepiolite to take the place
of asbestos as the reinforced materials of friction materials. The braking effect of the brake blocks is the best when the
ratio of the needle-like wollastonite to the fibrous sepiolite was 1∶6.
