“…Current-carrying friction is a process of coupling the frictional contact of a rough surface with conductive contact, accompanied by arc discharge and other phenomena [2,3]. The service behavior of different current-carrying friction materials is different, and the macroscopic performance is different [4,5]. With developments in science and technology, the service conditions of the current-carrying friction pair continue to expand, for example, the relative sliding speed continues to increase.…”

The copper matrix composites were prepared by spark plasma sintering (SPS). The current-carrying friction and wear tests were carried out on a self-made HST-100 high-speed current-carrying friction and wear tester, and the effect of the graphite content on the current-carrying friction and wear properties of the composite material was studied. The results show that with an increase in graphite content, the average friction coefficient and wear rate of the two materials decreased significantly, the fluctuation amplitude of the friction coefficient was also significantly reduced, and the average friction coefficient of copper-coated graphite composite with graphite content of 10 wt.% was 0.100; when the graphite content was the same and more than 5.0 wt.%, the average friction coefficient and wear rate of copper–graphite composites were slightly higher than copper–copper-coated graphite composites; the current-carrying efficiency and current-carrying stability of the copper matrix composite were obviously higher than that of copper material; there was a mechanical wear area and arc erosion area on the wear surface of the composites, with the increase in graphite content, the adherence and the tear of the mechanical wear area weakened, the rolling, plastic deformation increased, and the surface roughness decreased obviously. The surface roughness of the wear surface of copper–copper-coated graphite composites with graphite content of 10 wt.% was 3.17 μm. The forms of arc erosion included melting and splashing, and were mainly distributed in the friction exit area.

“…The second reason is that the existence of pores in the powder metallurgy with the sintered sample will decrease the conductivity [38]. The Ce and Ag with a good conductivity will be beneficial for the enhanced conductivities of the modified composites [39].…”

This work investigated the influence of reduced graphene oxide (rGO) modified with silver (Ag) and cerium (Ce) on mechanical and electrical properties of copper matrix composites. Powders of Ce doped rGO and Ag doped rGO were synthesized using a hydrothermal reduction and an electroless plating (glucose chemical reduction) method, respectively. Then, copper matrix composites with the doped rGO content of 0.25wt% were synthesized using ball milling and spark plasma sintering (SPS). The dispersion of the modified rGO and its bonding with the copper matrix have been signficantly improved. Hardness values of Ce-rGO/Cu and Ag-rGO/Cu composites were 26.3% and 16.4% higher than those of the sintered copper, and 19.4% and 10% higher than that of unmodified rGO/Cu composite. At the same time, the Ce-rGO/Cu and Ag-rGO/Cu composites maintained good conductivity and

“…To enhance the mechanical and functional properties of composites, carbon-based NMs such as carbon nanotubes (CNTs). − ,,,− graphene nanoplates (GnPs) ,,,,− and their combinations ,, have been widely used in CFRPs. Although the results of these studies serve well for their purpose, most of these processes rely on the chemical functionalization of CNTs and GnPs, which is an effective method, but it adds costs and causes damage to the CNT and GnP structure that deteriorates their intrinsic properties. , To lower the manufacturing costs of hybrid composites, it is ideal to use pristine CNTs and GnP; however, due to their strong Van der Waals attraction, homogeneous dispersion of pristine CNTs and GnPs is very challenging …”

Cellulose nanocrystals (CNCs) enable the effective coating of carbon fibers (CFs) with pristine carbon nanotubes (CNTs) and graphene nanoplatelets (GnPs). Herein, we articulate the mechanisms that form the interface of CNC-bonded CNT and CNC-bonded GnP-CF reinforced polymer (CFRP) composites that are suitable for structural applications. We show that CNCs provide a suitable platform to engineer the interface of hybrid composites. We demonstrate that the hybrid nanomaterials, i.e., CNC and CNT/GnP, alter the chemical composition of the interface and its properties, and despite the similar elemental composition of the CNT and GnP, the mechanical properties of the produced composites differ. Our results show that the presence of CNC–CNT and CNC–GnP creates a 4 μm interfacial region that leads to a 200 and 145% increase in interfacial shear strength and a 46 and 28% enhancement in interlaminar shear strength, respectively. Furthermore, density functional theory calculations show that the binding energy between the CNC–CNT and CF sizing agent is 14% higher than that of CNC–GnP underlining the effect of chemical and physical interactions in the observed difference in mechanical properties. The understanding gained from this study highlights a path forward bottom-up manufacturing of hybrid composites with an engineered microstructure and properties from the molecular level and nanoscale to higher scales.
