摘　　要：CNTs的高刚度、高强度使得其成为复合材料领域极有前景的纳米增强体之一。然而,单纯依靠实验获得CNTs对复合材料力学性能影响规律的方法是不可行的,需要辅之以合适有效的数值模拟方法去解理和分析CNTs各个因素对于复合材料力学性能的影响机制和规律。本文首先依据实验中真实存在的CNTs形态确定了模型为纳米-介观尺度模型,然后基于建模方式和研究对象的差异综述了三种常见的纳米-介观尺度模型数值模拟方法,最后根据目前的数值模拟结果,从CNTs本征性能,CNTs的含量和分布两大方面综述了CNTs对复合材料力学性能的影响机制,为数值模拟研究提供了可靠支撑,同时也为实验性研究提供了有力的理论依据。此外,由于数值模拟方法和CNTs变量的多样性,CNTs-纤维增强树脂基复合材料的数值模拟仍存在着巨大的研究潜力。As one of the most promising nanofiller,carbon nanotube has attracted more and more attention due to its extraordinary stiffness and strength.While it is not feasible to obtain the effects of carbon nanotubes on the mechanical properties of composites by solely relying on experimental methods,cleaving and analysing the influence of various parameters of carbon nanotubes on the mechanical properties of composites through numerical simulation methods has become a tendency.Based on the morphology of carbon nanotubes,the nano-meso scale model was proposed.Then three numerical simulation methods were classified depending on the differences between the way of modelling and the objects of discussing.In the end,the influencing law of carbon nanotubes on the mechanical properties of composites was reviewed from two aspects(intrinsic properties of carbon nanotubes,content and distribution of carbon nanotubes),which is expected to provide support to the credibility of results from numerical simulation method.In addition,due to the variety of numerical simulation methods and the diversity of carbon nanotube variables,the numerical simulation research of carbon nanotubes reinforced FRP composites still has great potential.
