abstract The paper presents the preliminary results of studies on obtaining copper-based composite materials strengthened with carbon nanotubes modified with copper nanoparticles. The nanotubes modification was carried out by chemically attaching copper nanoparticles originating from copper acetate. Electrolytically obtained copper powders were used as the matrix. The materials were consolidated by one-sided pressing followed by sintering. Microscopic examinations both of the powders and of the finished sinters were carried out using an Olympus GX41 optical microscope. Additionally, quantitative analysis of the sinters structure on non-etched microsections was performed. Computer software Image - Pro Plus was used to calculate the nanotubes surface fraction and their average surface area; the studied micro-particles aspect ratio was also determined. It has been shown that the nanotubes in the sinters, depending on the sintering method, differ in size and arrangement in the composite.
