I investigated the fracture mechanism of Carbon nanotube(CNT)/metal interface using first-principles calculation in order to enhance the reliability of CNT/Metal nanocomposites. As the result, the mechanical properties of CNT/metal interface in this study was affected by misfit strain between CNT and metals as well as their bonding.

为了提高碳纳米管/金属纳米复合材料的可靠性，本文采用第一性原理方法研究了碳纳米管/金属界面的断裂机理。结果表明，碳纳米管与金属之间的错配应变以及它们之间的键合影响了本研究中碳纳米管/金属界面的力学性能。
