Abstract

In this paper, the effect of copper metal powder and epoxy resin mixture on the fabrication process of the conductive glue system as electrical contact part of the brush to the engine on the naval battleship was studied. The copper metal/epoxy ratio in the glue was adjusted from 40 to 85 wt%, then evaluated by determining structure, conducting, and other mechanical properties. The optimal glue system has a very small electrical resistance of 0.0010 Ω, and a wire pulling force of 486.0 N. Results showed that the copper metal powder/epoxy composite glue system has properties equivalent to the currently used Russian product.
