abstract The paper presents the preliminary results of studies on obtaining copper-based composite materials strengthened with silicon carbides. Electrolytically obtained copper powders were used as the matrix. The sinters were characterized by different SiC contents (0, 5, 10, 15 wt.%). The materials were consolidated by one-sided pressing followed by sintering (T = 800°C, t = 1 h). One-sided pressing was carried out at the pre-set pressing pressure of 60 kN and at the rate of 200 N/s. The research was performed on powders, mouldings and sinters. Investigations of the composites comprised: microscopic examinations (SEM), chemical composition analysis (SEM), XRD measurements, the density of the composites was determined, and a quantitative evaluation of the porosity of the composites was carried out.
