各种阐明碳纳米管弹性特性的优秀实验成果层出不穷。这些主要是基于高分辨率透射电子显微镜（HRTEM）和原子力显微镜（AFM）技术来确定单壁纳米管束和多壁纳米管的杨氏模量，这些纳米管是通过多种方法制备的。这些结果证实了碳纳米管具有高强度以及非凡的柔韧性和弹性的理论预测。本文总结了近年来在理论和实验方面最显著的成就，在材料科学的广泛背景下解释了纳米管的特性，并强调了我们研究小组在这一迅速发展的领域的贡献。深入了解碳纳米管的结构顺序与其力学性能之间的关系，对于碳纳米管基复合材料的发展是必要的。迄今为止，我们的研究表明，纳米管的杨氏模量与壁原子结构的无序程度之间存在定性关系。其他令人兴奋的结果表明，复合材料将受益于碳纳米管卓越的机械性能，但在生产合适的工程材料之前，必须克服载荷传递效率的主要突出问题。
A variety of outstanding experimental results on the elucidation of the elastic properties of carbon nanotubes are fast appearing. These are based mainly on the techniques of high-resolution transmission electron microscopy (HRTEM) and atomic force microscopy (AFM) to determine the Young's moduli of single-wall nanotube bundles and multi-walled nanotubes, prepared by a number of methods. These results are confirming the theoretical predictions that carbon nanotubes have high strength plus extraordinary flexibility and resilience. As well as summarising the most notable achievements of theory and experiment in the last few years, this paper explains the properties of nanotubes in the wider context of materials science and highlights the contribution of our research group in this rapidly expanding field. A deeper understanding of the relationship between the structural order of the nanotubes and their mechanical properties will be necessary for the development of carbon-nanotube-based composites. Our research to date illustrates a qualitative relationship between the Young's modulus of a nanotube and the amount of disorder in the atomic structure of the walls. Other exciting results indicate that composites will benefit from the exceptional mechanical properties of carbon nanotubes, but that the major outstanding problem of load transfer efficiency must be overcome before suitable engineering materials can be produced.
