Abstract

Wear
mechanism of newly developed asbestos-free frictional materials (i.e. brake
pads material) was investigated by physical-mechanical experiments. The
suitability of the developed these new 
composite materials were investigaed by firiction testes at the different
temperatures. Thermal
investigation was performed by a differential scanning calorimetry (DSC) and
thermogravimetric analysis (TGA). Stability
and mechanical properties at different temperatures of the brake pad materials were
comparatively evaluated. Testing results showed that under the given
conditions, new developed frictional material has the advantages of the good
tribological properties over the widely used commercial asbestos enhanced
material as a FK-24A (Retinax, mark B). The research of the thermal and wear
behaviour of materials indicates that brake pair has better frictional
characteristics and wear resistance performance at high temperature. With
use of new friction brake pads materials will be improved the safety of braking
processes, and the quality in drilling will be increased. There is also an
environmental and economic advantages in using the new asbestos-free materials
in the break pads.
