Abstract A modified interphase model was developed to improve the physical error of the conventional interphase model. To examine the superiority of the new model, a multiscale analysis was performed to investigate the effect of the agglomeration of silicon carbide (SiC) nanoparticles on the mechanical properties of epoxy-based nanocomposites with a continuum damage model. Both interphase models could be effectively employed to describe the negative effect of nanoparticle clustering on the nanocomposite stiffness. Meanwhile, only the modified model was able to provide results corresponding to experimental observations in the case of nanocomposite strength. It was concluded that the strength and damage parameters of the interphase zone should be different from those of the neat polymer for the realistic design of polymer nanocomposites with clusters.

使用改进的界面模型对纳米 SiC/环氧树脂纳米复合材料的机械行为进行多尺度建模：纳米粒子簇的影响

摘要 为了改善传统相间模型的物理误差，提出了一种改进的相间模型。为了检验新模型的优越性，进行了多尺度分析，以使用连续损伤模型研究碳化硅 (SiC) 纳米颗粒的团聚对环氧基纳米复合材料机械性能的影响。两种界面模型都可以有效地用于描述纳米颗粒聚集对纳米复合材料刚度的负面影响。同时，在纳米复合材料强度的情况下，只有修改后的模型才能提供与实验观察相对应的结果。
