To enhance the properties of high-performance and multi-functional nanocomposites, it isimportant to accurately predict the macroscopic mechanical and electrical properties of the nanocomposites based on the information of nano- and micro-scale material structures. In this research, based on the construction of highly accurate sequential multi-scale numerical models for prediction of the mechanical and electrical properties of the nanocomposites, we uncovered the mechanisms of enhancement of matrix's mechanical and electrical properties due to addition of nanofillers. Moreover, experimental measurements of the mechanical and electrical properties of the nanocomposites were carried out for validating the proposed multi-scale numerical models. The design guidelines of the nanocomposites were provided by these multi-scale numerical models, which finally were used to successfully enhance the the mechanical and electrical properties of the nanocomposites.

为了提高高性能、多功能纳米复合材料的性能，基于纳米和微观材料结构信息，准确预测纳米复合材料的宏观力学性能和电学性能是非常重要的。在本研究中，我们通过构建高精度的连续多尺度数值模型来预测纳米复合材料的力学性能和电学性能，揭示了纳米填料的加入提高了复合材料的力学性能和电学性能的机理。此外，还对纳米复合材料的力学和电学性能进行了实验测量，以验证所提出的多尺度数值模型。这些多尺度数值模型为纳米复合材料的设计提供了指导，并成功地应用于提高纳米复合材料的力学性能和电学性能。
