The paper presents results of the tribotechnical and acoustic characteristics of copper-based frictional composite materials depending on the composite structure and content of metallic (tin, iron) and carbon (coke, graphite) additives in the composition. Changes in the studied characteristics are most pronounced under dry friction conditions. The introduction of the additives leads to reduced friction components of noise to 56 dB. In the boundary friction mode, the greatest effect of introduced target additives on the acoustic characteristics does not exceed 11 dB relative to the material without additives. For a composite based on 12% tin bronze, an increase in the graphite content from 10 to 30 vol % results in a 5 dB noise reduction.
