The paper presents the results of research on the preparation of composites based on copper matrix reinforced with silicon carbide (SiC) contents of 0, 5, 10 and 15 wt%. Materials were compacted by one-sided pressing, followed by sintering at a temperature of 800°C for one hour. One-sided pressing was used, with pre-set pressure of 60 kN and the rate of 200 N/s. The examinations of the composites included macroscopic and microscopic examinations (LM, SEM), XRD measurements, determination of density, hardness measurements, and a compression test. Microscopic examinations were performed using light microscopy (LM, 2D and 3D images), and scanning electron microscopy (SEM). XRD measurements were aimed to evaluate phase composition. The composites were measured using a Seifert 3003T/T X-ray diffractometer with radiation generated by a tube with a cobalt anode(λCo= 0.17902 nm). X-ray examinations were performed, with the measurements based on the symmetric Bragg-Brentano geometry. The computer software and the DHN PDS crystallographic database were used for phase identification. Hardness measurements were made using the Brinell method. The test results showed that the optimal content of silicon carbide in Cu / SiC composites is 10%.
