A Study on the Braking Characteristics for Some Non-Asbestos Kevlar Brake Pad Materials

비석면 케블라 마찰재의 제동특성에 관한 연구

An optimal brake pad must have stable friction, low wear and least amount of squeal. In this study, the friction, wear and squeal behavior of some non-asbestos Kevlar materials have been evaluated experimentally. Four specimens with different formulations and a pin-on-disk machine were used for this study. To determine the role of each component in friction and squeal of a brake pad, statistical correlations have been obtained and discussed. The components tested were : Kevlar, Steel Powder, Barium Sulfate and fillers combined by Resin.
