DESIGN OF COMPOSITE FRICTION MATERIALS FOR RAILWAY BRAKES

Friction materials for railway brakes are complex mixtures of fillers and other components in a polymer matrix. As a wide range of polymers and fillers can be used, materials can be designed to meet specific applications. The material, however, not only has to have the specified coefficient of friction ( mu ) and wear properties for the particular application, but it also has to meet a number of other requirements, for example, it must not cause thermal damage of the opposing surface, or wear the latter unduly, or induce brake squeal. It can be more of a problem meeting those requirements than in obtaining the required mu and wear levels. Consequently friction materials, after the initial design stage, are generally subjected to considerable development, and are tested and modified and tested again until the material is satisfactory in all respects.
