Ceramic fibre is made of high quality aluminosilicate fibre processed by short-cut man-made mineral fibre, its characteristics and role in the friction material are as follows: low hardness, virtual set up, can well absorb the friction material due to braking and the noise issued by the friction material.

It has good performance of high temperature resistance, very low thermal conductivity, it is attached to the surface of the friction material can effectively reduce the friction material in other low-temperature materials of the thermal recession and expansion, improve the stability of the friction material in the process of manufacturing and use.
