Morphological and structural features affecting the friction properties of carbon materials for brake pads

Six carbon materials, the widespread solid lubricant used in several applications, were selected for this study. The morphological and structural features were investigated with the purpose to understand how materials intrinsic properties affect the friction behaviour, using a pin-on-disc test applied to carbon powders against steel at different values of load and speed. The influence of test variables and material properties was studied using a chemometrical approach.
