Influence of the addition of 6, 7 and 8 wt% silica and 1–3 wt%. aluminum oxide and 1–3 wt%. dibutyl phthalate (plasticizer) on Rockwell hardness, Charpy impact strength and tensile mechanical properties was tested. The best properties were obtained for a composite containing 8 wt% silica, 3 wt% aluminum oxide and 3 wt% dibutyl phthalates. For this composite, the renal pelvicalyceal system was obtained using the FFF method.</p> Krzysztof Balawender Łukasz Przeszłowski Copyright (c) 2024 Polimery https://creativecommons.org/licenses/by-nc-nd/4.0 2024-04-17 2024-04-17 69 4 10.14314/polimery.2024.4.2
