摘要

复合材料液体成型技术是一种高效、低成本且环保的复合材料制件成型工艺。针对复合材料液体成型工艺树脂浸渍过程进行研究，采用有限元方法建立了多尺度树脂流动数值模拟模型，在微观和介观尺度对关键参数渗透率进行预报并与经典公式和文献中结果进行对比，在宏观尺度上将数值模拟结果与试验结果进行对比。在微观、介观及宏观各尺度下的对比验证，均取得了比较可靠准确的模拟结果，表明了研究方法的有效性和工程适用性。

Abstract

Liquid composites molding is a high efficient

low cost and environment friendly process to manufacture composite part. In this paper

multi-scale resin flow numerical simulation model is established and the resin impregnation process of composite liquid molding process is studied by FEM method. The key parameter of permeability is predicted at the micro and meso scales and it is validated by the classical formula and the results in the literature. The results by numerical simulation are compared with the experimental ones. The results show that the approach and model established are of high fidelity with engineering applicability at the micro

meso and macro scales.
