Abstract
In this study, carbon nanotubes at 0.05–1 wt-% ratios reinforced pure copper powder. Carbon nanotubes (CNT) were used to reinforce the copper matrix, these materials were synthesized under laboratory conditions. Ultrasonic processes and ball-milling method were used to provide a homogenous dispersion during production of the Cu-CNT composite. The Cu-CNT composite powder was produced as bulk material and then, the thermal conductivity as well as the microhardness of the composite were measured. As a particular result, it turned out that the thermal conductivity and the hardness of the composite increased up to a specific ratio of the CNT reinforcement, while the reinforcement ratio exceeding this critical level provided an adverse effect.
Kurzfassung
In der diesem Beitrag zugrundeliegenden Studie wurde reines Kupferpulver mit 0,05–1 % Kohlenstoff-Nanoröhrchen (CNT) verstärkt. Die Kohlenstoff-Nanoröhrchen wurden verwendet, um die Kupfermatrix zu verstärken, dabei wurden die entsprechenden Materialien unter Laborbedingungen synthetisiert. Es wurden Ultraschallprozesse und das Kugelmahlverfahren angewendet, um eine homogene Dispersion während der Produktion des Cu-CNT Kompositwerkstoffs zu erreichen. Das Cu-CNT Pulver wurde als Grundmaterial hergestellt und anschließend wurde die thermische Leitfähigkeit und Mikrohärte des Kompositwerkstoffs gemessen. Als ein besonderes Ergebnis stellte sich heraus, dass die thermische Leitfähigkeit und die Härte des Materials bis zu einem bestimmten Verhältnis an CNT-Verstärkung ansteigen, wobei ein Überschreiten des Verhältnisses den gegenteiligen Effekt erzeugte.
