Аннотация: The work is devoted to a composite material consisting of carbon fibres in a carbon pitch-basedmatrix. Due to its high wear and heat resistance, this material iswidelyused in aviationbrakesystems. Two samples with different impregnation of fibres were studied. It isshown that theirtribological propertiesaredifferent. Acomplex method of microscopy (optical, scanning electron,and scanning probe microscopies) was used to study thefrictionsurface andinner structureof the samples. In the sample with the best properties, the fibres havearegular ribbed side surface, fibrebundles arelocated parallel to the friction surface, matrix around the fibres hasadenserstructure. It is also shown that in this sample wearratesof the fibres and the matrix arethe same. Thus, a small change in theproduction process leads to a noticeable change in the structure, whichdetermines the operational properties.
