Fractal contact mechanics has been applied to the study of carbon-carbon aircraft brake materials. Prepared aluminum surfaces were also studied. The approach originally taken by Yan and Komvopoulos [J. Appl. Phys. 84, 3617 (1998)] has been corrected and modified to determine the real contact area as a function of applied load for any surfaces in contact. The methods are then applied to determine the real area of contact for the carbon brake materials in their application. A key finding of this approach is that the measured friction coefficient is shown to strongly depend on the contact area.
