为了系统梳理碳纳米管增强复合材料细观尺度的力学性能研究方法,综述了细观尺度分析方法(Mori-Tanaka方法、胞元模型法和均匀化方法)和有限元模拟法(渐进展开均匀化、Voronoi单元有限元法和细胞力学有限元法),并重点阐述了代表性体积元(representative volume element,RVE)的随机顺序吸附(random sequential adsorption,RSA)与随机序列展开(random sequential expansion,RSE)算法及其改良。结果表明,细观尺度有限元法能有效获取材料的应力-应变场,揭示其宏细观性能关联;引入碳纳米管可显著提升环氧树脂及碳纤维复合材料的界面强度和层间性能,为复合材料的性能优化与工程应用提供了重要的理论依据。

To systematically review the research methods for the mesoscale mechanical properties of carbon nanotube-reinforced composites, this paper reviewed mesoscale analysis methods (Mori-Tanaka method, cell model method, homogenization method) and finite element simulation methods (asymptotic expansion homogenization method, Voronoi cell element method,micromechanics finite element method). The review focused on the random sequential adsorption (RSA) and random sequential expansion (RSE) algorithms for representative volume element (RVE) and their improvements. The results showed that the mesoscale finite element method could effectively obtain the stress-strain field of materials, revealing the correlation between their macro and meso performance. It was demonstrated that the introduction of carbon nanotubes could significantly enhance the interfacial strength and interlaminar properties of epoxy resins and carbon fiber composite,and provides an important theoretical basis for the performance optimization and engineering application of composites.
