Composite materials based on a carbon fiber and a carbon matrix (C/C composites) are widely used in brake systems and other friction units with high loads and temperatures on the friction surface. The variety of structure and properties of the components of carbon composites causes different wear mechanisms during friction of these materials. These materials demonstrate numerous mechanisms of surface destruction during wear, often even for the same sample, due to the significant heterogeneity of the composite structure. The determination of these mechanisms and their parameters is an important part of the study of carbon composites. For these purposes, combination of scanning probe microscopy (SPM) and scanning electron microscopy (SEM) can be used.
