碳纳米管增强复合材料细观尺度有限元力学性能研究综述OA

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.
