TL;DR: In this paper, the authors used Mo2C nanoparticles grown on reduced graphene oxide (Mo2C@RGO) to prepare the 1.5 volumetric ratio of 1.1% Mo2c@rGO/Cu composite, which exhibited a yield strength of 238 MPa, 58% and 127% higher than that of pure Cu and pure Cu, respectively.
Abstract: Mo2C nanoparticles grown on reduced graphene oxide (Mo2C@RGO) were used to prepare the Mo2C@RGO/Cu composite. The Mo2C nanoparticles played a bridging role in not only being firmly attached on RGO but also forming a semi-coherent interface with the Cu matrix, leading to strong interfacial bonding of the composites. The 1 vol% Mo2C@RGO/Cu composite exhibited a yield strength of 238 MPa, 58% and 127% higher than that of 1 vol% RGO/Cu composite and pure Cu, respectively. The strengthening mechanism of Mo2C@RGO/Cu composite relied on the dual role of Mo2C nanoparticles that not only enhanced the load transfer strengthening of RGO but also provided the possible Orowan strengthening themselves. Nevertheless, the Mo2C@RGO/Cu composite showed a drop in coefficient of thermal expansion but a reduced thermal conductivity compared to pure Cu and the RGO/Cu composite. This study provides new insights into the interface structure, strengthening mechanism and thermal behavior of carbide-modified graphene/metal composites.

TL;DR: In this paper, a rational defect engineering strategy was proposed to tailor the interface and mechanical properties of graphene/Cu composites, and the composites with plasma-treated graphene exhibited a higher strength enhancement and better interface stability in response to thermal cycling, which was attributed to the CuxOy-coordinated improved interfacial bonding that provided efficient load transfer and thermal stress relaxation.

TL;DR: In this paper, the breaking strength of tungsten or molybdenum wires, uniaxially aligned in a copper matrix, was found to be a linear function of the wire content.
Abstract: T ensile tests at a variety of temperatures have been carried out on composites consisting of tungsten or molybdenum wires, uniaxially aligned in a copper matrix. Both continuous and discontinuous wires have been used, and both brittle and ductile tungsten wires. It is found that the breaking strength is a linear function of the wire content. A simple theory to explain this is developed and auxiliary experiments to check the theory are described. Some simple predictions about the behaviour of fibre reinforced metals are made from the results.

TL;DR: Carbon nanotubes are unique tubular structures of nanometer diameter and large length/diameter ratio as mentioned in this paper, which can be metallic or semiconducting depending on their structural parameters.
Abstract: Carbon nanotubes are unique tubular structures of nanometer diameter and large length/diameter ratio. The nanotubes may consist of one up to tens and hundreds of concentric shells of carbons with adjacent shells separation of ∼0.34 nm. The carbon network of the shells is closely related to the honeycomb arrangement of the carbon atoms in the graphite sheets. The amazing mechanical and electronic properties of the nanotubes stem in their quasi-one-dimensional (1D) structure and the graphite-like arrangement of the carbon atoms in the shells. Thus, the nanotubes have high Young’s modulus and tensile strength, which makes them preferable for composite materials with improved mechanical properties. The nanotubes can be metallic or semiconducting depending on their structural parameters. This opens the ways for application of the nanotubes as central elements in electronic devices including field-effect transistors (FET), single-electron transistors and rectifying diodes. Possibilities for using of the nanotubes as high-capacity hydrogen storage media were also considered. This report is intended to summarize some of the major achievements in the field of the carbon nanotube research both experimental and theoretical in connection with the possible industrial applications of the nanotubes.
