A unified framework is developed first time to determine 3-D permeabilities of fibre preforms for advanced fibre composites using homogenisation theories based on micro-, meso- and macro-structures of fibre preforms. Mechanistic models based on experimental studies, theoretical analyses and computational modelling are established to quantify permeabilities in different scales. It offers a unique technique to determine 3-D permeabilities for manufacturing advanced composite structures using various novel technologies based on resin impregnation or infusion, such as VARTM and RI. The outcomes of the project will fill the gap in the essential knowledge for cost-effective manufacturing of advanced composite structures in practical applications.

基于纤维预制体的微观、细观和宏观结构的均匀化理论，首次建立了确定先进纤维复合材料纤维预制体三维渗透率的统一框架。在实验研究、理论分析和计算模型的基础上，建立了不同尺度下的渗透率定量的力学模型。它提供了一种独特的技术来确定3D渗透率，用于制造先进的复合材料结构，使用各种基于树脂浸渍或浸渍的新技术，如VARTM和RI。该项目的成果将填补在实际应用中成本效益高的先进复合材料结构制造的基本知识的空白。
