“…The dependence of the hardness has a maximum at 0.5 wt. % FS attaining a value of 160 ± 4 HB, which is higher than the majority of the data reported earlier for any Cu-C composites [ 1 , 2 , 3 , 4 , 5 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. A further increase of FS concentration leads to the hardness falling down to 75 HB that may be explained by increase of Cu-boundaries quantity and appearance of soft FS agglomerates due to its inhomogeneous distribution.…”

“…One of the reasons of the ascending interest is the lower cost and the availability of the latter. Fullerenes were recently successfully used in composites on the base of aluminum [ 24 , 25 , 26 ] and magnesium [ 27 ]. However, to date, Cu-based composites with fullerene additions are barely discussed in the literature.…”

Copper-based composite materials strengthened with nanosized fullerene soot particles were produced by mechanical milling and hot pressing technology with a content of carbon up to 5 wt. %. The microstructure of the composite powders and the compacts prepared using them were examined by light microscopy, SEM, EDS, XRD, and XPS; hardness, heat conductivity, and tribological characteristics were measured. The interesting feature of the observed microstructure was a “marble” pattern formed by a white boundary net. The study shows homogeneous distribution of carbon inside the copper grains and its lower concentration in the grain boundaries. The effect was caused by a reaction of carbon with oxygen adsorbed by the copper particles surface. The maximal hardness of the material is 160 HB for the sample with 0.5 wt. % of fullerene soot; this material has the minimal friction coefficient (0.12) and wear in a dry friction condition. Heat conductivity of the material (Cu-0.5 wt. % C) is 288 W/m*K.

“…On the basis of the preparation method of graphene-reinforced copper matrix composites, the interface mechanism between nanocarbon materials and metal matrix has drawn increased interest, which can help elucidate the basic mechanical properties of composites to provide a theoretical basis for the design of graphene-reinforced copper matrix composites. An interface reaction occurs between multi-walled carbon nanotubes (MWCNTs) and aluminum, which can lead to Al4C3 generation [21][22]. According to density functional theory, active adsorption sites exist between Cu and MWCNTs, particularly on top of the carbon atom on the outer wall of MWCNTs.…”

Copper-graphite composite is an ideal friction material due to its good heat resistance, wear resistance and friction coefficient stability. The addition of Ti3SiC2 can improve strength, hardness and wear resistance of coppergraphite alloy material without affecting its self-lubricating properties and electrical conductivity. Two-dimensional graphene has become an attractive composite reinforcement owing to their unique electrical, mechanical and thermal properties. Cu/Ti3SiC2/C/Graphene naocomposite materials reinforced with graphene have been fabricated by vacuum hot-pressing sintering and hot isostatic pressing. Microstructures and mechanical properties of Cu/Ti3SiC2/C/Graphene naocomposite materials with different graphene contents have been systematically investigated. Microstructures of the composites were examined by optical microscopy, X-ray diffraction, back scattered electron imaging, scanning electron microscope with energy dispersive spectrometer and transmission electron microscope. The mechanical properties were determined from Brinell hardness, tensile, compressive and shear tests. Results demonstrated that there was an optimum value of graphene content which has an impact on microstructures and mechanical properties of Cu/Ti3SiC2/C/Graphene naocomposite materials. Based on graphene content on microstructure and mechanical properties of Cu/Ti3SiC2/C/Graphene naocomposite materials, strengthening and fracture mechanisms by graphene reinforcement have been analyzed.

“…They obtained that a tensile strength of the composite was higher than that of the matrix alloys. Shin et al (2015) fabricated a fullerene (C 60 )/Al composites and the damping properties of the composite were higher than that of the pure Al matrix. Moghadam et al (2015) reviewed metal matrix composites containing CNT or CF to improve not only tribological properties but also strengthening.…”

Aluminum (Al) based composites containing vapor-growth carbon fibers (VGCF) and carbon nanotubes (CNT) has been developed by authors for a decade using spark plasma sintering (SPS). It has been clarified that the thermal conductivity of the composite is three times higher than that of a normal Al matrix. The maximum volume fraction of VGCF within the composites to obtain high thermal conductivity was 60%. However, this high volume fraction of VGCF may have a negative effect on the strength of the composite. These composites are intended for use in controlling heat in radiation fins of a heat exchanger or a heat sink. Thus, strength properties and thermal conductivities of the composite at high temperatures should be precisely clarified. In this paper, temperature dependencies of both thermal conductivities and strength properties of the composite are investigated. Pure tensile tests and measurements of thermal conductivity by laser flash methods are conducted at high temperatures. Both the strength properties and the thermal conductivities of the composite decrease with increase in temperature. However, the decreasing behaviors of these properties were different in the Al matrix. The change in the strength of the composite due to temperature is smaller than that of the Al matrix and also smaller than the thermal conductivity of the composites.
