Experimental investigation of friction performance of automotive brake using Alumina and Titanium alloy

Abstract

Brake lining materials generally are asbestos metals and ceramics. Asbestos release the hazardous
gases during application which causes damage to the health. In this study had undertaken Experimental investigation of
Friction performance of automotive brake using different materials namely Alumina and Titanium alloy compare with
grey cast iron (GCI). In current study the wear, temperature rise and disk stopping time were investigated based on
analysis better suitable material for brake lining will be selected. The test rig was used to determine the performance of
the brake pads produced with the optimum manufacturing parameters and optimum composition. The pads were tested
for wear, disk stopping time and temperature rise. The developed pad A (Pad of cast iron with titanium and alumina
alloy) had greater wear resistance than the pad B (grey cast iron) at all speeds and loads. The comparisons for disk
temperature rise and stopping time shows that the developed brake pad has about the same performance as the
commercial (grey cast iron pad). The above results show that judging by the quality indices selected i.e. wear rate,
average stopping time and average temperature pad A is of a greater quality than pad B. Thus it can be applied in cases
where less weight is specifically required for good performance, such as Formula-1 racing cars.
