Abstract
Epoxy resin (EP) plays an important role in the field of friction, but its poor thermal conductivity limits its mature development in industry. To solve this problem, open cell copper foam (Cuf) and carboxylated carbon nanotubes (C-CNTs) were incorporated into the epoxy group as co-intensifiers to improve its thermal conductivity and frictional properties. The results demonstrate that increasing the pore density of Cuf/EP composite copper foam leads to a 33.6 % reduction in wear rate and 23.2 times increase in thermal conductivity when reaching 130 Pores Per Inch (PPI). Furthermore, increasing the content of C-CNTs in Cuf®(C-CNTs/EP) composites resulted in decreased friction coefficient and wear rate; at 0.75 wt% C-CNTs content, the friction coefficient decreased by 9.5 % and the wear rate decreased by 40.6 % compared to that of the (130PPICuf)/EP composites while also achieving a 54.8 % increase in thermal conductivity.
