Abstract

The article presents some results in research on the manufacture and evaluation of composite materials based on graphite-carbon oriented applications in the manufacture of seal ring. Composite materials are manufactured using a 3-step process: 1. Hot pressing of the mixture from phenolformadehyde resin and graphite-carbon powder mixture; 2. Sinter at a temperature of about 900 oC for 8 hours to coke the resin; 3. After coking, adsorb the product with epoxy resin at a content of (4-5)%. The material after manufacturing has a density of (1.82 ± 0.04) g/cm3; hardness (105.1 ± 2) HRF; friction coefficient (0.1647 ± 0.008); abrasion (48.2 ± 1.6) µm. The results of analysis and evaluation show that the manufactured material has physical and mechanical properties equivalent to the material sample produced in Russia, and can be used in the manufacture of the seal rings.
