COMPOSITION FOR MAKING ELECTRICAL PRODUCTS Russian patent published in 2024 - IPC H01R43/12 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to graphite-plastic powder compositions used for compaction of such articles as brushes of electric machines. Composition for making electrical articles contains high-disperse bronze “ПБВД-1” powder, carbon filler in the form of artificial graphite, a binder in the form of pulverized bakelite, and it also contains carbon fibre “Углен-9РБ”. Said components are taken at the following ratio, wt.%: pulverized bakelite – 19–20; high-disperse bronze powder “ПБВД-1” – 20–28; carbon fibre “Углен-9РБ” – 7–10; artificial graphite – balance.

EFFECT: invention increases strength and reduces electrical resistance of articles obtained from the composition.
