本文继第一部分的实验研究之后，重点对液体复合成型（LCM）过程中准球形纳米颗粒（NPs）的流动和过滤行为进行了建模和模拟。研究了NPs的双峰分散尺寸特征和预制体多孔结构的双尺度特征对悬浮液粘度、预制体渗透性和浸渍行为的影响。建模和仿真不仅有助于预测np改性基体体系的浸渍行为，还有助于反向研究可能导致滤饼过滤的临界粒径。
This paper focuses on the modeling and simulation of the flow and filtration behavior of quasi-spherical nanoparticles (NPs) during liquid composite molding (LCM), as a succession to the experimental studies in Part I. The influence of the bimodal dispersion size characteristic of NPs and the dual-scale characteristic of the preform porous structure on the viscosity of the suspension, the permeability of the preform, and the impregnation behavior is investigated. The modeling and simulation helps not only to predict the impregnation behavior of the NP-modified matrix systems, but also to inversely study the critical particle size that may lead to cake filtration.
