| Abstract Scope |
Low-dimensional carbon nanomaterials, including novel 1D carbyne and a 1D-2D hybrid, are materials that possess mechanical properties ideal for strengthening metal matrixes. However, the resulting mechanical properties of a carbon nanomaterial and metal nanocomposite are highly dependent on their interface. Using density functional theory and molecular dynamics, we investigate the interface and mechanical properties of Cu nanocomposites with low-dimensional carbon nanomaterials. We establish that their mechanical properties are influenced by temperature variation and nanomaterial density and dimension (1D or 1D/2D) in the nanocomposite. This is due to the effect of these factors on bond strength and effective load transfer at the Cu-C interface under tensile loading. We conclude that carbyne and a 1D-2D hybrid can strengthen Cu matrix and provide guidance for future development of effective Cu-carbyne and Cu-hybrid nanocomposites. |
